Downsize Fitness is an integrated wellness program for healthy weight loss.

Much more than a gym, Downsize Fitness is an all-encompassing health and wellness organization founded on the desire to improve the lifestyle of the individual. The methodology is rooted in a threefold approach:

  1. Physical fitness with customized, personal training modified to your fitness level
  2. Sensible nutrition that actually works
  3. Weight loss counseling to fostering a supportive environment

95% of our staff have weight loss transformations themselves.

Our gym is a community of people who have a significant amount of weight to lose and who are committed to doing so for the long haul.


Downsize is not a quick fix. We do not see it as such, and we coach our members to do the same.


We're highly empathetic to our members. Since we’ve been there before, and since we are still on that journey, we make amazing mentors who should be easy to talk to and learn from.

"We want to abolish the idea that there is only one kind of healthy."

Each individual’s success and growth takes shape through personalized routines.


Whether a member is new to exercising, has physical limitations, or is a veteran Downsize member, the program is customized so that each individual experiences positive progress as they work towards a healthier lifestyle.


We make it a priority to simplify weight loss, and practice a “one goal per member” philosophy.

Unlike any other gym, our members are our soul.

"I LOVE this gym! Finding Downsize Fitness was one of the best things that has ever happened to me. The staff and facilities are top notch, and the members are super nice and fun to be around. Everyone is very supportive of each other, and the environment is one of positivity and motivation. The staff and members alike look for you to be there and help you in your journey. It is definitely a place of love and support for overweight people to get healthy. They offer nutrition classes, group training, body composition measurements and much much more. The classes are dynamic and fun. I can not say enough great things about this gym, its staff, and the members."
