Best Workout Ever! It’s smart, intense and results oriented. Very challenging, but so worth it! You won’t regret it. Staff is great with newbies and fitness people alike. This is not your usual pilates class so BE PREPARED.

These machines are custom made and will ROCK you down.


I have been more than pleased with these classes and have finally found a workout that is changing my body in ways I have always wanted.

I encourage anyone and everyone to simply check it out. You will not only notice a difference in your body, but you will walk away feeling stronger and happier about your body. Too many people complain that they can’t change something, but with this class, you can change your entire shape. I am absolutely addicted, so I hope to see you there!



Motivational Cancellation Policy

An 8-hour cancellation notice is required to avoid being charged for the class, no exceptions. Members who miss a class or late cancel will lose that session. This includes making class time changes. If you cannot make class please go to your profile, ‘my info’ ‘my schedule’ and click ‘cancel.’ Any questions about our policy or waitlist please see our Policies Page.

Classes with fewer than 3 people might be cancelled, and instructors are subject to change at the last minute. You will be notified via email if class is cancelled.
