Default Re: Why is Air Alert bad for you? GOOD READ

i started doing air alert 2 but stopped because i heard that it might screw up your muscles. i am only 13 so don't want to do weights. my vertical is really poor so i was wondering, if air alert is bad, then are their other jump programs that don't require weights
