what are pilates 100?

Answer 1

Pilates

Developed by Joseph Pilates in the 1920's, this method of body conditioning
strengthens and tones muscles, improves posture, provides flexibility and
balance, unites body and mind, and creates a more streamlined shape.
It is a tried-and-true formula for improving endurance and stamina.
It is for these reasons that ballet dancers seek out this machine-less
method of building & maintaining a dancer's body.
One of the core moves of Pilates is '100's which challenges your abs and back in a whole new way as you take your legs to a 45-degree angle while pressing your hands up and down.
