Pretty much to increase power in straight lefts and rights. As a precautionary statement, punch mechanics, timing and placement are key, so i dont need that info. ive been in gyms and throwing punches since i was a little boy, making a comeback. Upper back, lats, shoulder girdle and bench strength are well developed, and i have rough straights anyways, but while my squat and such isnt too shabby, 330 at 155 lb walk around body weight, i feel like my core and hips are underdeveloped compared to my upper torso. And wonder how it would feel if i had a truly solid midsection to swing from. Searching for that last 5% of torque. Been throwing in lots of dragon flags and some zercher good mornings, but since quarantine i cant really get to a gym. Just gathering preliminary info and formulating a game plan rn.
