Our story


How we got our start
I needed a lot of physical therapy, the process left me with tired and overworked muscles. Frustrated with the compression of smooth rollers, I developed a better product that would penetrate deep into the soft tissue, and help to flush lactic acid while blasting away painful muscle adhesions.
What makes our product unique
Our products are engineered from the ground up. We invest heavily in R&D to rethink the size, materials, construction and densities of everything we make. We partner with industry leaders to develop 4K eBook content as companion guides into the proper use and techniques for each product.
Why we love what we do
Our customer feedback is what makes my day. We get a lot of emails from customers that describe the challenges their bodies are facing, and how we have improved their lives and their outlooks. It feels great to know that you had a positive impact on someone, it never gets old.

Customers are mixed about the chalk distribution. Some mention that it is OK,dispensing a small amount of chalk and doesn't create a mess.

useful for what you pay for
Okay i was a bit scared at first but i did be careful with what i used during and after or even before i out it on because if you had lotion or hand sanitizer it would give you the brutal blisters and we all know they’re e ugly and painful. but i rinse my hands before use and after of course. i then afterwards like after washing my hands with soap i then use my hand sanitizer and i’m fine. another good thing is it doesn’t stain your clothes if you just wipe your hands on your pants, after a wash it removes without any smell. (i’ve heard things it leaves your clothes stained or smelly) BUT I APPROVE IT DOESNT !

5.0 out of 5 stars Great chalk, great price
Reviewed in the United States on November 30, 2022
No issues at all with this chalk. I use it for climbing several times a week.

Pro tip: Don't waste money on a chalk ball. Go to the shoe store and grab one of those little nylon disposable socks that ladies use to try on shoes. Fill it with chalk and tie it off. Works great!
