While most of the exercises in the Hamstring Series focus on, well, the hamstrings, some exercises also let you get in a core workout. Keeping your pelvis floating off the bench while doing these small bicycles is a total body exercise that emphasizes core strength.
Most of the exercises in the Hamstring Series are done while you'd laying on your back. But like on The Ladder, there are a few exercises when you're side lying. This allows you to move in multiple planes of motion at once.
Isolation exercises, doing a single joint motion in a single range of motion isn't the GYROTONIC® Training way of things. Every exercise is multiplanar, multiple muscle & joint groups and you always have to be aware of your entire organism. Total body, total breath, total mind. And yes, the breath is in the middle. The breath is binding agent between the body and the mind.
