How can I learn to punch harder? I am already pretty fit but feel that I am lacking in technique.

What sort of training have you already done?

I have not trained with any fighting techniques but I have weight trained. Can you provide me with some basic punching technique advice?

Punching techniques are just like with weight lifting or any other skill.  If you work on it and practice, you can improve a lot over time.  In fact, it’s better to start by getting some coaching in the form.  You could find a local MMA gym, or look for some boxing or kickboxing classes near you.

There are two main questions I think you have.  The first is how to punch harder, but the second is whether your training regimen is a good fit for self-defense.  Are you looking for either or both?
