Its all about technique, you cna have a porshe... but if you can't drive for shit you may aswell have a larder...

My mate can bench well into the 300s I can barely becnh in the 200s. I punch probably 5-10 harder than he can and thats with the 2 stone weight advantage...

Fitness and strength are important, but technique comes first.

Your leg muscles are more important in punching than your arms are.
