“Sacrifice pays off!” – Arturo, 1331 + visits at CORE40

CORE40 super client Arturo Levin

After 6 years of regular attendance at CORE40, Arturo has more energy, less stress, and has seen big improvements in his overall physical performance.

When did you first discover CORE40 and decide to give the Lagree Fitness® method workout a try?

“I started in February 2010.

How did you feel after your first CORE40 class? 

“Awful! I thought I was in decent shape and that 40 minutes was not going to be enough. My first class was with Kim, who was a very toughdemanding instructor. After 10 minutes, I sat at the end of the “bed” thinking “What is this??What am I doing here?”‘

How often do you workout at CORE40? 

“5 times a week.

What are the health benefits you feel from doing the Lagree Fitness® workout consistently over the years? 

“I find several, not necessarily in this order:

It keeps me in shape.

It helps me to control my weight.

It boosts my energy.

It keeps me healthy and helps me combat diseases.

It relieves stress.

It improves my mood (goes together with item 5).

It improves my brain power.

And the #1 reason I do it…

It helps improve my sexual performance (at 60 years old, I need this one)

And related to all of the above, it makes me feel better about myself, because it increases my self esteem!”

Here’s to a thousand more visits, Arturo! 


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
