At an advanced Level 4 coaches course hosted at his gym, QCK in Regina, Marcel Dubois explains a machine he uses to condition the entire body at one time.
It’s good.
A suspended athlete must show body flexion / extension. This movement pattern (sometimes called the “curvilinear action”) is used over and over again in gymnastics and tumbling.
Marcel designed his machine after those he saw in the former Soviet Union in the late 1980s.
At the end of the video, the same action is demonstrated without the machine, requiring a lot more spotting by the coach. The demonstrator had never used the machine before filming.
