Sofia Vergara

“The workouts kick my butt in the best possible way.”

“I love that it’s only 40 minutes but packed with intensity. The cadence and pacing of this class is just PERFECT.”

“I LOVE CORE40 – it’s changed my life and how I work out.

EXPECT TO SWEAT. Expect to tire out your muscles in the most efficient way possible. Expect to do slow, controlled movements which is not all about physical ability, but mental capability as well.

Janice C.

As a professional ballet dancer, I have found this to be the best workout out there. If you want a hard (and I mean really hard 40 minute) workout this is the place to go.

Kirsten A.

Amazing total body workout. My body has changed so much with this workout, and my balance is even better. I have long lean muscles, and I feel so much stronger.

To Our Beloved Community,

Impact is one of our core values, and even in the face of uncertainty, we believe there’s always room to positively influence our community. We’ve been offering virtual classes since we temporarily closed our studios’ doors, and we are blown away by the incredible outpour of encouragement in your comments, emails, and messages. We’re committed to delivering at-home workouts and wellness tools during this temporary shutdown.

For those of you who would like to contribute to the ongoing creation of our digital wellness offerings, please feel free to do so, here. If not, that’s ok too. We’re honored to play a part in your journey, and we’re here to help you shine. 

While we can’t host you for class at the studios right now, we’re offering new video streaming classes on our social media pages to help you move at home!
