Simone makes a good point. Doing many exercises quickly turns them from being a strength move into a cardio move.
Doing them slowly is actually harder, as the muscles are working to maintain you in the knees-bent position.
Doing them quickly is easier on the muscles, but the rapid up-and-down works the heart more and turns it into a cardio move.
The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself. Therefore all progress depends on the unreasonable man.
