hey guys I have got myself an uppercut punch bag. I want to increase my speed and my combination range. I can ofcourse do a simple 1-2 combo. can somebody give me tips on how to get better at what I want.
Get a trainer. Work on your stance, guard, posture & balance. Work on your jab -- the most important punch in boxing. Work on throwing short punches, like your arms are just an extension of your body.
