What are good things to make your punches stronger?
 

ive read that punching the heavy bag helps but how fast? Ive read that if your stomache gets stronger your puncs get stronger...that are som good work out methods to get your punches much stronger? Do push upshel?

What Martial Arts do you do?? I'd recommend weight gloves, they work well.

right now I only do crappy shotokan...but im about to go to a schooland try and take up kickboxing/wrestling...i just want some tips to start out with b4 i start kickboxing

Like SuzukS said, weight gloves work well. Power punching involves your whole body. Try to avoid arm-punching (punching using only your arms) which is taught in some traditional martial arts schools. As you work the bag focus on putting all your body's momentum into your punches. The force behind your punch starts at your toes and ends at your knuckles.

if you don't mind pain, i recommend putting nuwspapers on a brick wall and punching it straight for 2 hours. Thats the way Shaolin do it

Good technique = power and speed, work your jabs and crosses untill your moving fluid and fast. Then you will get power.

I agree power has nothing to do with it. I know people who are twice as strong as me but I can hit ten times harder than they can because I have ben practiceing kempo and kickboxing for 6 or 7 years now. put your hip into it turnover your punches. use your whole body in your power punches not just your arm. nothing beats years of practice.

dont do that!
I know a guy that got in to that hands of stone stuff where he would hit bricks and rocks. He said his hands were littely that stone. he said It killed the nerves in his hands and his hands were so stiff and rugged that he couldn't even make a sandwich for himself. It took a while but he finaly got his hands working again. So they are good for hiting but that is all they good for.

hit frozen/raw meat like rocky. You will become tough and bloody

Practice, with time it will come, just make sure you do it right
