I train on a wall bag,pads,spar,heavy bag,do straight blast with dunbells in my hands and weight train to aid and improve my punch power. what more can i do to increase my punch power? I also concerntrate on tecnique.

Work on the specific tecniqe and flexibility in your hips. Let them initiate the punch. Let the move begin in the hips and then upwards your body. See your shoulders and hands as only the deliver of the power made in your hips. So begin the movement in the hips letting it go up in your relaxed shoulders and hands. Only in the sec. on impact tense up in your hands and shoulder. And of course let the punch hit inches behind your target.

all so i would serguest
chi gun as well, improves your breathing from the dow che en
and tiger push ups. you can finde out how do them in most kung fu books or wing chun/ jeet kune do.
