I was referred to Mike (Genetics Gym) by another fitness instructor who had been a client of Mike's. That fact alone is a good indicator of Mike's skill; he trains other trainers. His training is personalized to each individual client. This is NOT a one-size-fits-all training program, like CrossFit or Orange Theory. My training with Mike has been exactly what I had hoped for; a custom program based on an initial evaluation of my capabilities and focusing on MY goals. Mike does a great job, you won't be disappointed.

I started training with Mike four months ago after getting a stern talking-to from my doctor about needing to make some serious lifestyle changes. She encouraged me to start strength training. Sounds simple enough—until you go down the fitness rabbit hole on the internet trying to figure out where to start. That’s where Mike and Genetics Gym come in.When you start working with Mike, the first few weeks of workouts are designed to assess your current fitness level, flush out any mobility issues, and include conversations about your long-term fitness goals. After the assessment period, Mike uses the results to design a personalized program to help you achieve those goals.The best part of the program for me is that Mike provides the where, when, and what, and all I have to think about is tying my shoes, showing up for an hour, and pushing the weights around. This is really what you’re paying for. It’s not a traditional gym membership—it’s a full-service fitness program. Workouts are scheduled and tracked through an app and are varied enough that they don’t get boring.With all the workouts being scheduled, I’m generally there with the same five or six people every morning, so it’s never very crowded. Mike floats from person to person, helping set up equipment, providing a spot, explaining a new lift or movement, correcting form, and answering questions. I’m usually in and out in just under an hour. Everyone at the gym is friendly and welcoming, with a wide range of ages and fitness levels, and it’s not intimidating at all. We’re all there for the same reason. I'm glad I took the leap and join Genetics Gym.

I initially found Mike at Genetics Gym from another workout instructor when I wanted to switch things up with my normal high intensity workouts into more lifting. That was over a year ago and I’ve been really happy with the switch! Genetics Gym has a very welcoming atmosphere and Mike gives great individualized workouts. I was also in the middle of fertility treatments, then pregnancy, and Mike made all the accommodations for what I was needing in workouts for each phase in my fertility journey! I’m now postpartum and I can’t wait to get back in the gym! Would highly, highly recommend Mike!

I stumbled upon Genetics Gym by Google searching “strength training gyms in St. Louis.” After perusing the website and meeting Mike, I knew there was something special here. I continue to be impressed with the customized programming based on my goals (even remote programming while OOT), but more than anything how welcome I feel at my new gym. Mike is very knowledgeable, delivers great cues, and always has a pulse with what each client has going on for their particular session. I’m excited to be a part of this community and get out of my workout rut. 5 stars for sure!

I’ve been working with Mike at Opex Gym in Maplewood for a month now. I’ve worked with other trainers in the past and Mike far exceeds my past experiences. Other trainers were knowledgeable and showed me many, many exercises to do in the gym. But I always walked away knowing lots of things I COULD do, but not having a definitive plan to work out at the gym on my own. Mike is much more focused. I learn something from him every time I train with him, and the focused approach gives me a baseline I can work from when I’m traveling and working out on my own. Another really great point is the knowledge and expertise Mike applies to each individual client. He customizes the experience based on each person’s abilities and he can “read” each person’s body to design the perfect workout. I’m a 65 y/o female, and have found myself thinking, “There’s no way I’ll be able to do that exercise.” But each time I express my doubt, Mike reassures that he thinks I can, based on what he sees in how I move. He encourages me to challenge myself and I can definitely feel myself getting stronger and more fit. There is plenty of great equipment at the gym. And the gym is clean and a pleasant place to work out. I highly recommend this gym for anyone serious about improving your health and getting more fit.

Mike has provided a safe, comfortable space that I actively look forward to working out in. He is very patient with my slow morning brain and extremely thorough with a training program that addresses my specific needs. I have already recommended him to a few friends! I really could not have asked for a more supportive, thoughtful gym.

Been working with Mike for a couple.of years now. As a 55+ year old I am very happy with his programming accommodating my age. The gym is clean and has all the equipment I need.

The gym is a great community. Mike listens and programs workouts to achieve personal goals. The gym is never crowded, it is always clean and everyone is very friendly. Mike has improved my form, built strength in muscles I didn’t know I had and is someone I look forward to working with for many years to come. If you want a personal trainer feel without personal trainer cost, this is the gym for you.
