Well that is not true ,it was bad for what you were trying to showcase , i gave you solid advice the SAME post ...here was your basic response "Your opinion is sh*t, and your analytic skills are garbage, and you sound like a low quality human being who in general isn't good at life. You legit could be Charlie Z." Not that i care ,i know you didnt concave any bag , i wonder why a FIFTY pound weight is on TOP of a HB when that would do absolutely nothing ????? I wonder why you said the bag wasnt hung high( it clearly is because its a few feet off the ground and you can see how high the ceiling is, you then claimed higher bags are harder to move which is another off center remark ,because the more weight on the bottom with less chain is what will give the bag more resistance ...either way im out ...let steel help you ,im done here im not even getting into your physical appearance because it would have to do with putting on lean muscle ,thus i would have to give advice in things you believe not to be important....lol But here my last post for steelshoulder to break this down for you i certainly am not taking time out for you ,ironically steel the guy who agreed with everything i said ....im not going out of my way this is it and shouldn't even post it ! Power comes from your core and the shoulder. Legs aren't a necessity to hitting hard.the twisting motion from mid body is what generates the power .For shoulders just do alot HB work and punch high level and do in between periods with a speed bag hung high where you are reaching up to burn the shoulder , if possible. Dont overwork shoulders they will grow with bag work anyway. Do lat excercises because its a huge muscle that helps drive the punch and reinforces it. Forearm and wrist ,this will help absorb impact and make you hit harder( I get my power from my Forearms...G. Foreman), you can only hit as hard as you hand can support which is supported by the wrist/forearm. bicep curls /resistance training bicep routines will help hook punches. All in all when throwing a punch everything has to work together and that's shoulders/lats/bicep and thats alighned with the core twisting of the hook and proper leg stance that will get you the most power,and you always punch through the target when throwing maximum power because in real life you are trying to break bones or knockout someone. look at video footage of who you think is a power hitter you resemble and overall you tube vids from beginners hitting to coaches to fighters,you learn more visually then reading a book, unless you have the power concept down already.
