My coach told me today that the supercat machine is one of the best, if not the best, thing you can use to increase your vertical leap. He said that the man who invented it, did it for his son when he was in 9th grade. The boy worked diligently with it, and by his senior year, he had gone from his 9th grade 19 inch vertical to a 48 inch one!
Is this machine really that great?
