Jack training - corrected:

Back foot closer to the rear hip. Proper rotation of the rear leg and shoulder, no shift to the left hip. Full bodyweight on the right hand.

The day they called his right hand "Dempsey" :-D

Could you please post a video of how to throw a proper left hook using the old school stance?

[@OBCWarDogs]

@@miguelyarturo For sure.

[@rodya_malverde]

There's an example if you look up Luis' old tile exercise video.

Please make a jab tutorial. I don’t care much for other punches. Well, not as much.
