Bill Neider was one of the best physical specimens in throwing in all time. He basically taught a generation to always focus on "the perfect throw" and tried to make everything he did make the shot go farther.
It is a great lift, but whether or not you (the general "you") need to do it depends on what you are trying to do. You will be humbled quickly by it. If you can get to snappy reps with 200, you are one of a kind.
