Doctors and fitness experts agree that squats are one of the
most important exercises you can do, using 65% of the muscles
in your entire body per rep. It is also well known that individuals
tend to have trouble balancing themselves while performing the
squat exercise. Numerous stationary squat exercise devices have
been designed to assist in balance by constraining the motion
of the user. These devices usually have a bar that travels along
two parallell tracks to assist the user.
