I was wondering if anyone has any great ways for increasing their vertical? I am a long 6'4 170lb and I can just hardly touch a 10ft rim. At the gym I do calf raisers with the leg press and also do leg press, but its kind of limited because my left knee is still kind of hurt from a wierd injury last year. There is no pain, just akwardness with it. What other exercises and things can you do to increase vertical other than calf raisers, leg press, and squats? Do you think its possible I could be dunking by summer? Thank you for any advice you have!
