Hello, It is simple to grow 2-4 inches in vertical leap in just two weeks by using the correct training system & have a good nutrition plan. My friend gained 9 inches within 12 weeks and now he can 360 dunk with two hands.
I don't know if I understood you? 80 hours of wear on the bands? That's not very much? I'm thinking of purchasing them but now concerned about how many times I will have to replace parts.
