This is what some refer to as a “finisher” that I like to throw on to the end of upper body workouts from time to time. Other people may refer to it as a Mechanical Advantage Set. Watch as I start from the hardest position, toes on the ball, and take that just short of failure. From there, I walk myself back a bit further, ball around the knees, and take that to failure. And then from there, I walk to the last position, ball around shin level, and take that to failure. Give it a shot.
