not quite. When lifting weights you have constant resistance throughout the movement. When hiitting a bag unless your pushing that bag after you hit it the weight wont matter at all, since we retract our punches after we throw them. The force that your going to apply to the bag has already been created before you make contact, and since you dont make further efforts to move the bag after that then theres no gains from using a heavier bag.
So your trying to say a guy hitting a 50lbs bag will have the same punching power as a guy punching a 150lbs bag? That'll be your little secret :thumbsup
yes, the force is created before you connect, but how can you ignore that simple equation? Ok, instead of moving the bag, let's say when you hit an 80lb. with a left hook, it takes the force and wobbles back and forth for pretty long.....if you hit a 100 lb. bag and it wobbles back and forth the same way for the same amount of time, that is increased punch power. Just go to a sporting goods store and hit an empty standing bag and watch it fall over.....and then (hypothetically) buy it and fill it up. if you can eventually knock it over with it full of sand, your power has increased through hitting it.
both of you have valid points, i think there is no point of continuing this argument, there is no right or wrong answer to this.
of course if you can move an 80lb bag by hitting it and then move a 100lb bag the same distance you have increased punching power. what im saying is that its not the heavier bag that makes you more powerful. otherwise everyone would be buying 1000lb bags to get as strong as possible.
