People say air alert hurts your knees.
I am going into my sophomore season in football playing 4th string receiver behind 3 seniors.
I want to get my vertical jump up by next year so when i play, i would be able to jump higher than 22 inches. (current vertical)
Also i want to get faster. I know you have to sprint to get fast but i want to have an organized workout for speed.!!!!!!!!!!!!!!!
Yes ,do leg press but instead of pressing, let the weight come down slowly then explode (This simulates jumping) this strengthens the muscles used to jump
