The Experience, In Their Words.

It was so slow and humbling in the best ways possible. I swear I felt muscles I never knew existed! Will for sure be back and couldn’t recommend more.

Roos

The studio is wonderful and you get to do your workout with remarkable trainers! The routine itself can be challenging, but manageable. After a few times you can already feel your body transforming. I love it!

Chris

Outstanding Lagree instructors who make every class enjoyable and motivating. Clear guidance, great energy, and a wonderful atmosphere.

Sarah

I’ve been going to CORE40 for 6 years now and the instructors are the best, very focused. They make sure we’re all engaged and doing the right exercises, while encouraging us to push our boundaries and compete with no one but ourselves!

Brian

Each trainer has their own style and all are very helpful to strengthen your body!

Other workouts blur together, but CORE40 classes are so memorable because of how you’re challenged in each and every exercise. It’s what keeps me coming back!
