Old Norse Athletics/CrossFit Dyr has recently moved into a new larger space. In addition to CrossFit, they now also have tons of brand new weight equipment, free weights, cardio equipment, and an infrared sauna. The workouts are great! All of the staff are very knowledgeable in fitness and nutrition. I love the way all of the workouts are scaled to your individual fitness level.

CrossFit was the workout I was looking for but didn’t know it. My daughter talked me into it, and now I love it! It’s always different and challenging. I love the coaches at Dyr CrossFit, they do a great job of pushing us, but also making sure we are practicing good form and staying safe.

Update: I’m about a year into my CrossFit journey and still loving it! I am still a work in progress, but definitely stronger. Highly recommend! 💪🏼 Less

Great coaches!! Challenging workouts that are adjusted to meet your needs/skill level. Lots of class time options to choose from. Welcoming community..newly expanded gym offering 24 hour access. Owners and coaches are vested in meeting your goals. After a year I would not go anywhere else!

Very helpful staff, I was new to CrossFit when I joined this place and the staff is always giving great pointers on how to do the lifts/exercises properly. Great, difficult workouts plus they have tons of workouts a day, so it's very easy to work it into your schedule.

If I could give more stars, I would! The new space is amazing with lots of equipment. The 24/7 access is terrific, group classes are challenging and coaches are amazing and inspiring. Everyone is so friendly and it's a wonderful community!!

My first CrossFit gym. Couldn't ask for better coaches! Everyone is very friendly and supportive. *Update January 2025 - Been a member for over a year now and the gym has grown (bigger space, new equipment, sauna, etc...). The owners and coaches keep things interesting with goals and activities. I highly recommend dropping in and trying a class. If you stick with it, you will be hooked.

Best CrossFit in the area! James and Sherry (owners) are friendly and very knowledgeable! All the coaches are very good as well, always happy for any class! The gym is very spacious with and it has CF and a regular gym to meet any needs. One thing I love is that their bathroom is extremely clean!

CrossFit Dyr/ONA is a gem of functional fitness in the Mystic area. The coaching keeps athletes honest with proper form on lifts while encouraging scaling if needed.

Great facility with great equipment and open gym set-up to boot. They were very accommodating with memberships and allowing me to join for a short time while on a contract in the area!

Great facility with a great community. Highly recommend for anyone looking for a CrossFit gym or just a very nice, clean, modern workout facility.

Great gym. Supportive community.

Very welcoming gym community while I was living in the area for a few months!

Love how big the gym was and 10 minutes down the street from me. I was visiting from new orleans. Coach sherry / Shannon was wonderful for the 9am class! Made me feel very welcome and helped push me for my work outs!

CrossFit Dyr has been a great experience! Everyone is very helpful and knowledgeable. I have no previous experience with cross fit and was a bit worried and self conscious, it is totally a judgment free zone!

Great environment! New to CrossFit so it was a little intimidating but was immediately welcomed into the group with lots of pointers and support from coaches.

An amazing experience. I enjoyed working with the instructors as well as other members. They were able to create a diet plan as well as a workout regiment that helped me accomplish my goals. I would highly recommend this gym.

Great experience only wish I was at different place in life now to continue as I am relocating to a different state. Highly recommend this CrossTrain if anyone is looking to improve themselves.

Great place to workout. Coaches and members are also great and definitely makes the difference. No egos, everyone encouraging each other.

In town for the weekend. Coach was very welcoming. Had a great time.

Love my Local Crossfit!!♡♡♡

Awesome place to work out. Very knowledgable staff and great attention to detail.

James and Sherry are excellent coaches and owners! I dropped in a for a few classes while visiting friends in town. Clean space, plenty of class times to choose from, new equipment, and friendly coaching staff.

Great workouts and space!

Coach James was awesome making the drop in process easy. The gym was organized and spacious. Good experience overall.

Dropped in to a Friday morning class with Sheri and the gym is very large and spacious. Sheri did a great job explaining the workouts and giving options for scaling. Warm up was coach led and her cues were great as she made sure to help every person in class. Atmosphere was fun and the workout was great. Definitely would drop in again.

I lived in Groton just for the summer and was warmly welcomed by all the coaches and members at Dýr. The new gym is large, fully stocked with all necessary equipment, and the programming is strong (and cardio heavy). Sherri is not only a coach but can be a resource for nutritional needs, and Shannon is a rockstar coach who motivated early morning workouts. If you’re new to CrossFit or a seasoned ... More

Sherri & James were very welcoming ! they are super knowledgable to the sport and have great programming. I love it there!

It is a very good place, since it has everything you need

Great gym, lots of class times to come. I’m enjoying the 6 week summer challenge. It has gotten my fitness and nutrition back on track.

These guys are absolutely amazing. I came in at the beginning of the summer out of shape and only one month in I'm feeling amazing. I'm doing a nutrition program set by them and it's going great so far. Everyone is so nice and helpful. No one has an ego.

CrossFit Dyr is great.Super welcoming and friendly. The coaches will scale down and modify so you are successful. The have plans to expand in the fall to have more traditional gym amenities also. The 6-week challenge they offer is a great introduction to Dyr.

My boyfriend, Nick, and I had an amazing experience at Dyr. We attended an incredible 8:30am Saturday class. I appreciated the helpful demonstration and modeling from Sheri. The gym is beautiful, clean, and huge. Staff is warm and welcoming. Members were friendly too!

After not being active for over 6 years I knew I wanted to better myself, but I also knew I didn’t have the motivation to go to a regular gym and make it happen all alone. That’s why I decided to try CrossFit and I definitely don’t regret it. The coaches are great and it’s a very welcoming environment. I’d recommend this gym to anyone of any fitness level!

Today I had the pleasure of visiting the facility and was nicely greeted by Sheri and several members of the class I had showed up for.

Great energy and very nice people which was pleasant to wake up to. Class was well programmed with a nice warmup transitioning smoothly into the strength portion of the WOD which consisted of power cleans. Sheri did a great job of explaining the progressions. And then onto the WOD which was jump rope (double unders) and v ups. Overall I had a great total body workout, just what I needed to get my weekend off to a great start and I look forward to coming back whenever I’m in the area! Less

A great environment to begin your workout journey. A friendly and knowledgable staff is there to challenge you. Every rep counts because you count them. A hidden gem in Groton/Mystic. Well worth it. You owe to yourself a quality workout with no distractions. You need to start somewhere and CrossFit Dyr is highly recommended for all levels.

I have never exercised like this before. Face to face accountability and encouragement. Challenging, fluctuating exercises that don’t get boring.

Best gym in area. Really liked the exercises the coaches had picked out for me. Prices are extremely fair and gym is conveniently located near highway and RT. 184.

Great drop-in box in the Mystic area. Great WOD, helpful trainer and great atmosphere.

Very welcoming environment and an excellent workout!

Everyone in this gym has been welcoming since day 1! The coaches are so knowledgeable and guide you every step of the way

I dropped in from NJ and the first thing I noticed was how nice the facility was, tons of room and equipment all well maintained! The best part of CrossFit Dyr though are People who train and coach there. Such awesome people, such wonderful experience

Great atmosphere, very welcoming within 3 weeks already feel and a huge improvement after being out of the gym for 5 years dealing with an auto immune disease

If you’re looking for a friendly and supportive community— you’ve found your place!

This was my first experience with crossfit and it so far has been a great time. The coaches are knowledgeable and very friendly.

I was nervous to try CrossFit, but it has been such a fun experience. I lift heavier than I ever have because I feel comfortable with a coach always watching your form and available as a spotter. The group classes have kept me motivated and excited for more progress across multiple skills.

An awesome environment of people with a common goal - to get you a good workout! The community here is so welcoming, kind and very positive. My favorite CrossFit gym I have worked out at to date.

The coaches are spectacular and very attentive. Each movement is coached and thoroughly practiced. CrossFit Dŷr has that workout community I’ve been looking for.

Great gym, friendly staff

Positive atmosphere, good programming and coaching. 10/10 would recommend.

Overall good experience. Great amount space to allow freedom to do classes or use as open gym.

Great place to workout, coaches are very knowledgeable and very friendly. Love the community feeling in this gym!! Highly recommend.

The best place! Everyone is like family and is so encouraging

Great gym with even better coaches! Such a great community that encourages everyone to improve. I recommend Dyr for someone of all levels. Ask for James, he’s the best!

Everybody treats you like family here! Best crossfit gym ever!

I found the strength I was looking for when I joined this gym. The coaches and the owners push you to become the best version of yourself. I am happy to be part of this CrossFit community knowing that they have my back and they want to see me lifting more weight than I think I can lift, because they know I can.

I love the classes they offer! I am developing strength that i never thought would be possible at my age! I’ve had back surgery and love how they work with me on form. They also show me how to modify movements so i can get the most out of my workout without hurting myself!

This place has helped me exceed my fitness goals! Great staff and a great environment to become a stronger and overall better person!

Awesome place to work out,such a great vibe!!

Great environment for beginners or people who have been doing CrossFit for a long time. They definitely make CrossFit less intimidating than other gyms, they are into adaptability especially for injuries or beginners, or if your like me and are both. Really positive attitude from most of the coaches.

Coming to CrossFit Dyr was my best decision of the year. Excellent workouts, great atmosphere, and helpful coaches are the perfect mix for improving health and fitness. I recommend Dyr to everyone I know, it’s truly that good!

The team at Dyr have really pushed me towards reaching my fitness goals. The family atmosphere is unlike any gym anywhere and makes some of the most grueling workouts enjoyable.

I participated in a 6 week body transformation and couldn’t be more happy with my results! Owners and coaches are great!

Great gym

Great workout every time. Best crew to train with. CrossFit Dyr for life!

My second home❤️. Such a great community. I can’t explain how much I’ve improved in CrossFit over the past year. Dyr has helped me reach my fitness goals and given me so much more than expected.

I lost 16 lbs so far , the 1 on 1 attention provided is amazing. They make sure you are doing each and every movement correctly, coaches work with you and it makes you feel more motivated especially on those days when you do not want to work out .

Great owners, coaches, and members - Very welcoming and accommodating for anyone who joins

I joined Crossfit Dyr for the 6 week body transformation program and lost 20 lbs and gained muscle by following their healthy diet guide and attending 3 classes a week. I love the varied workouts that never get boring and work different muscles. The coaches help you lift safely and effeciently as well as encourage you to reach your potential.

I love CrossFit Dyr because the workouts push me harder than I would or could on my own. I always think I can’t make it through but I do and I always leave feeling better about myself and what I accomplished. The Staff is awesome and the music rocks!

As a coach for the gym, starting as a member, I can't say enough about the ownership and their drive to always provide the best possible experience for every level of individual looking to get in shape... I would love to see you there to experience our great atmosphere for some hard work and noticeable improvement in strength, stamina, and functionality!

Super friendly and welcoming Gym! The coaches are excellent at adjusting all work outs to every level and it's a great place to get healthy and make friends!

Phenomenal gym. Awesome folks. Can’t recommend it enough.

I had a great experience with Crossfit Dyr! The instructors were all super welcoming, informative and put a premium on safety. I would recommend this location. to anyone looking for a great workout community!

Great spot for a drop in! Love the space and coaches!

Definitely one of the best CF gyms I been to, since starting my CF journey over two years ago. What you don’t realize is that not every gym performs a lift and does decently long and tough WOD.

Overall a fun and exciting way to train your body into shape! Trainers: all trainers are fun and never over aggressive (this comes from someone who's been around quite a few gyms) This matters when you are trying to stay motivated and that's strictly coming from experience. Training routines: it's really cool cause you have three options no matter the level you are in level one being a routine anyone can do. Level 2 being more challenging but still something most people can do and level 3 being this more challenging route for the more experienced. Everyone workouts at the same time so it's a great time and there is no real pressure unlike other places I've been to. Less

Great gym! Friendly team and fellow cross fitters. Dropped in frequently over a few months and loved it. Wish I was in mystic more often to enjoy Dyr

My favorite place to workout 💪

CrossFit dyr is awesome, learned a ton and was pushed to do better with every workout.

My go to place

Great gym awesome coaches

When I moved to Groton the CrossFit Dyr community took me in and made me feel welcome. I’m glad for spending this year here and getting to workout with an amazing group of people and coaches! I enjoyed the workouts (even the one with wall balls lol) and it s was definitely the best part of my day. I’ll come back to visit and drop in for sure! Ps: best CrossFit gym in the area!!

This gym and program is great. I wasn't seeing the results I wanted from the purple budget gym because I needed a plan and coaching. I'm getting it at Dyr. Everyone gets personalized attention regardless of skill level. It's not easy, but when you leave, you feel great about what you were able to accomplish. I highly recommend Dyr.

I’m from the UK and dropped in to this Crossfit gym a couple times while visiting Mystic. Absolutely loved it. Such welcoming and friendly people and great coaching too. So glad I found this place!

Sheri & James are amazing people and coaches. The other coaches they have added are very knowledgeable and friendly. Everyone is always willing to help you improve and become the best version of yourself. This is the Best CrossFit around! I consider family!

I have been attending for almost a year and I can't even begin to describe how much this place has changed my life for the better. Great, friendly staff and amazing community.

worst experience with any CF gym in the country. Worst experience with any local business in this area.

Nice gym, great people - an excellent place to drop in. Thanks!

So happy to have found a gym that cares about their members! I’ve been going to CrossFit Dyr since Aug 2019 as a personal training client. Back then it was hard for me to find enough motivation to go to the gym because I absolutely hated working out. I was someone who was intimidated by CrossFit because it looked beyond overwhelming and difficult. Even though I felt the way I did, I still decided to make the switch from personal training to CrossFit in July 2022. Switching over was honestly the best decision I’ve made for my mental & physical health. The owners Sheri & James, along with the other coaches always make me feel so welcomed every-time I go. After 6 mos of doing CrossFit classes, not only am I stronger and more confident, but I am no longer that girl who dreads going to the gym. Thanks CrossFit Dyr for being like a 2nd family to me!

Thank you so much for working with me last month. I am looking for a crossfit gym in my area. I really enjoyed yours!

Love the community here!

I love getting all the help I need with getting myself back in shape again after a long period of inactivity and letting myself go.

Great facility, plenty of room, fun workouts and a warm community!!! Highly recommend 💪🏻💪🏻💪🏻

Friendly and professional trainers, great workout

Great experience!

Awesome gym! I love the vibe....always feel welcome.

The coaches are amazing, the atmosphere is wonderful, it's a great place to workout and become a better person wether you want to be stronger, faster, more flexible it doesn't matter if you're an athlete or not, CrossFit Dyr is for everyone!

My wife and I only started going a couple of months ago, but we love this place! Since moving to the area a year and a half ago, we have attempted to work out at home. We bought some equipment and figured we would save money and time in the long run. My wife stayed pretty dedicated. I got comfortable on the couch and started eating snacks.

My wife and I only started going a couple of months ago, but we love this place! Since moving to the area a year and a half ago, we have attempted to work out at home. We bought some equipment and figured we would save money and time in the long run. My wife stayed pretty dedicated. I got comfortable on the couch and started eating snacks. In short order I was back to “the worst shape of my life”. My wife and I had been members at another CrossFit gym in CT and found that the community was a huge part of the reason we showed up every day. We have been missing that. So I decided to reach out to a handful of local places and see if we could drop in and check out the box. After the first session at CrossFit Dyr, we were hooked. Sign us up for life! There are plenty of classes throughout the day, the members are all friendly- even when we go at 5:30 am, and the coaches have been amazing. They know when to push you and when to pat you on the back. I’m probably the worst “athlete” in the gym and they already have me doing things I haven’t done in over a decade. If you’re looking for a gym/ box that really feels like they want the best for you, give CrossFit Dyr a try. I can’t wait to see what they help me accomplish next Less

Whenever I make it to Mystic I come here at least once. Great programming, attentive coaches and friendly members. Clean facility and fully equipped with Rogue equipment. Can’t recommend highly enough!

Coaches are very friendly and knowledgeable. James and Sheri helped me feel welcome since day one and it is a great community to be involved in. As a new member to CrossFit, Shannon helped me learn all of the exercises and encouraged me through the workouts. Gym is very clean and the equipment is in great shape. Highly recommend this gym!

I dropped in to CrossFit Dyr while on business travel. They responded quickly to my request to drop in. Both of the owners greeted me. The box is just the right size with all the right stuff. The workout I attended was a good one - challenging and fun. Highly recommend you check them out if you’re in the area.

My wife and I only started going three weeks ago, but we love this place! Since moving to the area a year and a half ago, we have attempted to work out at home.

Great Gym and Friendly staff had Plenty of weights and space on the rig for me to complete my workouts. James was easy to schedule with and it was nice to have the gym more or less to myself. I will definitely be coming back here when I am in area to drop in again.

It’s a nice gym and the coaches are nice and very welcoming. Definitely going to go back when I return to Mystic.

Dyr is an inclusive gym that fits with my life’s crazy schedule. I was looking for a change from the monotony of a big box gym and found the workouts to be super fun, always challenging and effective.

Great coaches, good workouts with lots of variety. Definitely recommend for an encouraging community with solid options for scaled workouts. Recommended for one on one PT, for a lot of strength building.

Great space. Great vibe. Great workout.

Absolutely monster workout that put my strength training to absolute shame. Not for the weak, but if you’re weak, they will treat you like you’re strong. Fighting for my life right now, but thankfully did not die!!

Great experience, coaches are pretty knowledgable and easy going

I must say, I hate taking my rest days because I have so much fun working out now. This gym and the warm community it has fostered throughout the years have helped me rebuild my relationship with exercising (and now nutrition)!

Having been to a couple boxes in the past for work, I can honestly say I’ve found an incredibly dedicated group of people that push me better than ever. The WODs are varied enough for all skill levels and the Open Gym time is a great opportunity to build on other skills and techniques. Sign up - you won’t regret it! Less

Sheri is a terrific guide and coach! A lot of energy here!

Beginner to CrossFit and I was super nervous and intimidated to join, but needed more of a push in my life. The owners and members were so welcoming and go out of their way to help me along this journey. Couldn’t be more thankful I found a great gym on the first try!!!

I’ve known Sheri for quite sometime, as she was my trainer prior to joining this CrossFit gym, at another gym facility a few years ago. She has always pushed me, and motivated me. This gym is amazing. Everyone is so welcoming, and they provide great instruction. I’ve been going for almost 2 months now, Monday thru Friday.

I’ve known Sheri for quite sometime, as she was my trainer prior to joining this CrossFit gym, at another gym facility a few years ago. She has always pushed me, and motivated me. This gym is amazing. Everyone is so welcoming, and they provide great instruction. I’ve been going for almost 2 months now, Monday thru Friday. The app they use is very easy to reserve classes, shows the workout of the day, shows who is attending, and you can put your personal bests in. James and Sheri are always so supportive and provide individual attention to all who attend class. If I look a bit confused or doing something wrong, they are right there to help me correct it. Besides the owners, the trainers who work there do the same. In all honestly, the entire CrossFit Dyr family (staff and members) does the same. I have never felt more welcomed and more supported at any other gym facility. The registration was very easy, straightforward, and detailed; explaining what was included. I feel incredibly lucky to have found a fitness community, filled with all levels of athletes, that encourage each other to do their best! Less

After losing a gym I loved dearly CrossFit Dyr came into my life and I couldn’t recommend them enough. The workouts kick my butt in the best possible way and the community was warm and welcoming. Happy to have found my new fit fam here at Dyr.

I love the workouts & the community that I am a part of by being here, the workouts are intense but they are rewarding nonetheless. I look forward to coming here every day I can

Good weight, get strong

Every time I have a class, I always leave with a sense of accomplishment. Sheri (trainer) motivates you to finish the workout and makes sure the weight is appropriate ability or skill level. 10/10 always have a good time working out

Love coming to this gym! Was in a workout slump & decided to start working out here... the atmosphere and motivation is unbeatable! Love the owners & coaches.. very knowledgeable & personable. I have never been to a gym with such a great community. 10/10 would recommend if you want to get in shape and make some friends!

Best workout of my life! The coaches are the best and so nice and helpful. Crossfit sounds intimidating but it's just a great workout that can be adjusted to any skill level.

Crossfit Dyr is a great local gym and I am glad I found it! Sheri, James, and the other coaches are very knowledgeable in Crossfit, power lifting, general fitness, and overall health. Thier programming is unique and cannot be found straight off the internet, including cardio days, Hero WOD days, and strength combinations I have not seen before. Everyone has a great, positive attitude in the gym and I always feel welcome. They maintain a close neighborhood gym feel, but still have more than enough specialty equipment. They are also handling COVID-19 changes well, incorporating home workouts, Zoom sessions, and socially distanced motivation. I highly recommend checking them out! Less

The atmosphere is unbeatable. The coaches are encouraging, supportive, and very knowledgeable. I cannot say enough GREAT things.

Sheri and James are awesome coaches. They do a great job motivating you as well as developing diverse and challenging workouts for all skill levels. The gym equipment is top notch too, all new rogue equipment.

Amazing coaching from all of the coaches. Always a fun atmosphere. Any level of athleticism can join, they are good at structuring the workout to whatever you can/cannot do. Such a high level or energy during the workouts to keep you going during the toughest workouts!!

Been there over a year and never felt so strong or confident in my whole life. Great support, encouragement, fun and can proudly call all of them my friends.

Try it once and you’ll be hooked! All the coaches are knowledgeable and super friendly!!

This place is amazing! Huge clean gym with brand new Rogue gear... the owners and coaches are top-notch... I love the comradeship here... with athletes of all skill levels...

CrossFit dyr was the best decision I made while traveling in the area. I felt very welcomed when walking through the door. If you’re looking to join because you live in the area or traveling, try them out I doubt you’ll disappointed!

Up and coming gym with an unbeatable price and even better coaches. Worth every drop.

Very clean and well staffed

I went last night to check out Crossfit Dyr. the coaches were attentative providing slight tweeks to form during the WOD. The equipment is top notch in that it is Rogue. They have spared no expense on the equipment for a brand new box.

The building itself is so beautiful and everything is brand new, there are also supplements and snacks you can buy to help you reach your goals. I have been going for a few weeks now and every time I go it’s a great/challenging experience. If you are interested in learning new workouts and challenging yourself this is the place to be. Less

The Grand Opening of CrossFit DYR was amazing. A great big Congratulations to the owners/coaches. They are energetic, enthusiastic, attentive, and know their stuff. The grand opening was a tribute to them for all their hard work in putting this wonderful gym together. What a great event...they had a local radio station airing live, they provided free chair massages, the chamber of commerce gave them a plaque and hosted a ribbon cutting ceremony. The warm up before the work out of the day was a free yoga session of stretching, etc. to get us started....how cool was that! I am new to crossfit and the days workout was a team pairing. I was with an individual who has never done this before and the coaches made certain that anyone on the floor who was new got individual attention before (setting them up and showing them the routine) and throughout the workout to ensure they were ok, doing everything properly (to their personal ability) while encouraging and supporting everyone (some 20+ people). It was Amazing and I was very impressed. There was even a celebration after the workout with free pizzas and beverages. I highly recommend you get to this facility and make DYR crossfit a part of your lifestyle. You won't regret it. And your first workout is free! Less
