Revolutionary Lagree Fitness® Method
on state of the art Megaformers®.

Achieve increased and lasting strength.

Push past your imagined limits.

Connect your body, mind, and spirit.


I’ve tried all the copycat methods. Don’t waste your time. Lagree or die!

It’s the best thing you can do for your body.

“I really love the workout. In less than an hour you feel like you do everything your body needs.

Sofia Vergara

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

Bryan A.

“I’ve only been to CORE40 a few times and I’m already hooked.

Sophie C.

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

Ariana P.

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

James G.

Within ONE MINUTE of using the Megaformer I was breathing heavily. Within FIVE MINUTES I was shaking...

Emily V.

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,

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
