The essence of the Exercircles stations is using hydraulic pistons to provide resistance to a motion. When you move a piston up as in a Bicept Curl
and let go, nothing drops as you would experience with weights. When you push the piston down you exercise the
tricept. The up and down motion works both muscle groups of the upper arm.
Each exercise is designed to work
the opposing muscles in a muscle group.
This is both an efficient
and effective form of exercise.
The level of exertion is controlled in two ways.
One is by changing the setting on the resistance knobs and the second is to try to go faster.
