CORE40 Full Body with Marisa

CORE40 Full Body with Eric
Left my legs shaking - such a great workout!
CORE40 Full Body with Elena
My preference is to have instructors who have a challenging class but not borderline impossible to do with perfect form. I'm not motivated by inability to complete the exercise and was a little surprised by the difficulty level given there were newbies. (have been doing core40 on and off for 4 yrs)

About this studio

In just 40 minutes, you will experience the most revolutionary core-focused, full body workout in the fitness industry – one that not only works over 600 muscles per session, but in many cases works several hundred per exercise! In each group session, you will be trained by a CORE40 SuperTrainer, who is masterful at combining the benefits of Pilates and weight training (strength), yoga (flexibility & mindfulness), and cardio (interval training) with less time, more intensity, and no impact on your joints.

How to prepare

WHAT TO BRING/EXPECT... • A towel, if desired (CORE40 is an ecoconscious organization and does not offer towel service due to the water waste it creates). • A water bottle, which you can fill using our filtered water system. • Please wear anything you might feel comfortable doing yoga or running in. • The CORE40 workout is done wearing grip socks (recommended) or barefoot. We have grip socks for sale at the studio. • Expect a high intensity workout! • Refer to our online FAQs for more helpful info
