Our focus

Your Fitness. Your Nutrition. In Our Judgement-Free Atmosphere.

Constantly varied functional movements performed at a high intensity. It’s a core strength and conditioning program that’s easily modified for your individual fitness level.


Incredible fitness, done at your own speed, while having an incredible amount of fun. No yelling, no screaming, just motivation. Come ready to flip tires, swing a kettlebell, throw a ball against a wall or even drag a tire! Every day is different!

Sweat Box

This is fast becoming a favorite class! It’s a combo of TRX, Bosu training, low weight/high reps and HIIT workouts. You’ll never know what to expect. Every move is easily modified for your fitness level.


It’s never too late to start again! If you’re age 50 or older, and ready to reboot your fitness level, this is the perfect class. Small class size, lots of one on one attention and care!

Open GYM

We realize “life gets in the way” sometimes. We happily offer open gym times. Please check our schedule!
