Foundation Training Back Extension
This back extension exercise is different than some of the other back extension exercises, like supermans, you seen performed in the gym.
Notice that the hips and thighs stay on the floor and the muscles of the inner thighs are contracted to anchor the pelvis and the face is pulled away from the floor. Decompression breathing is used to create the extension in the back, strengthening the muscles along the spine while creating much less compression than a more traditional back extension.
Look for upcoming Foundation Training workshops in early 2020 to learn how to do this exercise and other Foundation Training exercises.
