You need no manual adjustment or training devices, the human body is the most advanced technology. The SAFE® FLOOR concept is as innovative as it is inclusive: slow dynamic micro-movements practiced in spiral; they literally transform muscle fibers that tend to ossify.

In other words, one class suffices to feel an intramuscular hydration.
