GET STRONGER.
LIVE LONGER.

This place is awesome. So much care, effort, and knowledge goes into each week’s cycle of workouts. I started working out with Matt years ago. I’m so glad he finally has his own space. It’s been at least 6 years since I’ve had the energy to get back into it but man I’m so glad I took that step. The format is simple and engaging which for someone with a limited attention span who gets bored with repetition has been great. Every day there’s a new set of exercises. Matt and his staff take care to make sure that each movement is explained, modeled, and monitored. I’ve been working out for about 10 weeks now 4x a week and I am stronger and thinner. As someone who plays sports I am noticeably jumping higher too. Best part- my back doesn’t hurt any more. I recommend this place to anyone who wants to take their fitness journey to the next level. Cannot recommend it enough. Update- it’s been a full year now and my arms are toned and stomach flatter. When I first started I could barely bench a 45lb bar- now I can fully bench 10reps of 65-80lbs. Pants that I haven’t worn in 6 years now fit again.

I trained with Matt for several years before moving to the East Coast seven years ago. While recently visiting California, I had the opportunity to participate in the Friday conditioning class, and it did not disappoint. ​Matt is still incredibly engaged with the class, expertly motivating the group while providing the individual attention each participant needs. The best part is that the strong family atmosphere I have always appreciated and enjoyed is still present—a direct result of the positive culture Matt has prioritized building over the years. ​So, if you're looking for a top-notch strength and conditioning program that produces results and fosters a community where members truly encourage and motivate each other, I highly encourage you to check it out!

This place is amazing! I booked a session using Class Pass. I was totally hooked. Matt is an excellent trainer and made me feel comfortable. I was looking to do resistance training and as a woman in her late 50’s I was a bit nervous. I was contemplating hiring a personal trainer but it was cost prohibitive. Cozmosize Fitness offed semi private training that was exactly the right fit for my fitness goals and my budget. The workouts are challenging but you get through them with everyone cheering you. I love the positive energy and I would encourage anyone to give this place a try

My two daughters and I have been training with Matthew, and we couldn’t be happier. He makes fitness fun, especially for the girls. They’re always excited to go workout! He is very organized and his plans are clear to follow. His positive energy is amazing and sets the tone for the entire group! It’s such a motivating environment to be a part of. Everyone is very supportive and encouraging. It is a very friendly space. I know I’m in the right place and I’m very excited to see more and more progress week after week.

Cozmosize Fitness has truly flourished since moving to their new location on Railroad Avenue. The spacious facility has transformed into the perfect environment to get stronger, better, and leaner while working toward your fitness goals. I was first introduced to Matthew Cather by my 17-year-old son 11 years ago, and at the time, I thought it was the toughest workout I had ever attempted. I started training with Matthew twice a week, and now I train five times a week--growing not just physically stronger but also mentally resilient. As a 52-year-old, I firmly believe that the key to longevity is a combination of weight training, strength, mobility, and conditioning--all of which are seamlessly incorporated into our program at Cozmosize. The dedication, expertise, and sense of community here make every session both challenging and rewarding. I feel truly blessed to be part of the Cozmo family, and I highly recommend this gym to anyone looking to elevate their fitness journey!
