Our Promise

There’s no other studio that delivers a low-impact and high intensity workout the way we do. From our studio aesthetics, our curated music, and our top-notch team of caring coaches, our promise is to deliver an epic experience every time, with no detail left to chance. We believe it’s not just about what we do, but about how we deliver results that truly makes us the most effective workout.

We pride ourselves on being innovative, and that includes the equipment. Our Megaformers® were created as an extension of your body, so the carriage is smooth and light, like driving a luxury car.

Along with the equipment, we add a unique mindfulness element into our classes, because we believe the mind is inextricably connected to the body. Our instructors are trained in meditation to really tap into your mental strength throughout class, because we believe that a Strong body + a Strong mind = an Epic life.



Elevate the intensity of your Megaformer® workout to a whole new level with the latest Lagree Fitness® Ramped technology. CORE40’s studios are the only studios in the Bay Area to offer this incredible innovation. Available at select studios.


Hardcore. Effective. Efficient. Safe. What’s not to love? Our signature class, using the revolutionary Lagree Fitness® Method, was developed to give you the best possible workout in the shortest amount of time. Use slow movements (to target slow twitch muscle fibers, scientifically proven to burn more fat), resistance training (to build muscle strength), continuous tension (via spring resistance) and constant engagement of your core (on a moving platform) to push your muscles to maximum exertion and keep your heart rate elevated throughout. Stretch your limits as you burn 500-800 calories per class.


Power. Intensity. Cardio. A trifecta of awesomeness. CORECYCLE is core-focused endurance training at its finest. In 40 minutes you will leave sweaty, out of breath and inspired. Power through climbs and sprints to pulse-pounding music as you use your CORE to help you reach the finish line.

To Our Beloved Community,

We are beyond grateful for your love and support during this unprecedented world health crisis. The outpour of your thoughtful messages for CORE40 are truly astounding, and we are incredibly thankful to play a part in your journey. 

Given San Francisco’s recent announcement, we are not yet able to reopen with the 10% occupancy guideline. Unfortunately, at 10% capacity, we cannot afford to pay our business operating expenses. Upon further review of the situation, and as it progresses, we will provide another update as soon as possible.

Even though we are not able to reopen yet, we are excited and hopeful that things are moving forward in San Francisco, so we can reopen very soon.

We are committed to doing everything we can as an organization to continue supporting our community with virtual content during the shutdown, and we need your help to ensure we can reopen our doors for you when the time comes.

Due to many of your ample requests to support CORE40, and in light of the shelter-in-place extension, we are moving our live streams to our class schedule, which will need a “virtual class” purchase of $20 for registration in each live-stream.

You can expect Lagree-inspired at-home workouts led by our awesome team of CORE40 SuperTrainers. All the information you need regarding future live streams can be found here:

For those of you who are not in a position to support at this time, you can still view our past streams on the CORE40 IGTVYouTube, and Facebook pages.

And remember, together we rise. 

With love,

Team CORE40
