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. 415 776 2673

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 wastage 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 class! • Refer to our online FAQs for more helpful info

CORE40 Ramped with Joyce
Great, challenging class! It would be great to have hands-on adjustments so that I can improve my form on the exercises.
CORE40 Ramped with Leticia
This class was uninspiring, the instructor never smiled, seemed to be upset the whole time. Music selection was off putting, we were forced to listen to elevator music for the duration of our workout. There was ZERO enthusiasm in her voice, it was like she was a shell of a human being. Horrible experience and another reason why I won’t be coming back until they get better instructors. Core40 used to be the soul cycle/Barry’s of Pilates. Now it’s just a mess. Do better. Not worth the price.
