Hi i was wondering if any of you have insight on how to improve my vert jump and how to help develop my arm muscles.
Im 14 turning 15 in a couple of months and im 5"11. my vert jump atm is approx 21 inches. I also want to improve my arm muscles because i can never get the power to hit hard enough in volleyball, i struggle to do more than 2 chinups and i only weigh about 60kg.
Any information on this would be greatly appreciated. |
