My friends and I decided to form a boxing club, and I plan to take it seriously. I'm a pretty skinny kid (130 lbs), and I'm gonna be taking on 150-lb guys. It's pretty much impossible to beat them strength-wise, so I wanna work on my speed (dodging, ducking, dashing) and build up my strength to a point where I can manage to knock them down if I have an opening. So I basically wanna focus on attaining unparalled speed in the ring and just some exercises to build strength (upperbody and arm). Think anyone can help me out? Thanks a lot.
