Xtreme Fitness is such a wonderful addition to the Harvard community. They provide a very welcoming environment for all levels of fitness; beginners, local sports teams, those who have been working out for many years and also those looking to stay sharp later in life. The space is always improving, expanding and offering new options. Jill and Gerardo continue to create a fun environment for people to better their lives with fitness, nutrition and friendship. Classes are offered for both early risers and those who prefer later afternoons. They accommodate the needs of their patrons and truly care about each person who walks through the door. Expansive healthy food and drink offerings at the cafe just add to the overall experience. The tea drinks, protein shakes, protein cold brews and baked goods are all top-notch and reasonably priced.

I have been a member with XFN for almost 2 years now. I started with Zumba and then joined full time. It was one of the best decisions I’ve ever made. This place is not just a gym it’s a family a great community to be apart of. Jill and Gerardo have made it such a safe and non judgmental place. Working out alone for me was hard and being able to have the guidance and verity of workouts has been great! If you are debating on joining don’t just do it!!

I’ve been coming to Xtreme Fitness since high school and through my college years, and they have truly been wonderful. The staff is always friendly, welcoming, and willing to help. They offer a great variety of equipment and classes, so there’s always something new to keep me motivated.What I appreciate most is how much they support the community, it really feels like more than just a gym. I’m grateful for a place that cares about its members and the town it serves. Highly recommend!
