I'm 25, actually. too old to be so unskilled in the art of boxing. I don't mean to be a troll in the sense that I want to be a serious figher, I have taken advice from a lot of people here seriously, and as to the other a lot of what I say is true, about how far/fast I can run, my lifts (which are kind of laughable besides the deadlit) the maul and sledge work, the conditioning, and occasionally when I do transfer my body's size and seed well, in a well linked punch, hit the bag so hard and heavy it makes a thunderous clap even when I hit it near the bottom. Some left hooks, brutal.
I do plan to get into a gym and train, so I can consistently link my best shots. One example is that I miss the "power line" that Dempsey so stresses, sometimes, arm is too low in relation to my back and shoulders. Thus losing a lot of the coordination of a punch, losing the snap my powerful back muscles can help produce.
some of what I say is true, some of it is over-estimation. I pounded at the heavy-bag until I had developed fairly okay abs and back musculature, the reason being I am hitting with force. I have a muscled up back, because when I hit properly it feels like god touching your back. for every action there is an opposite reaction, if that reaction is enough to put on pounds of muscle, chances are I am hitting hard.
I know of no way to "direct" this energy away from my body, in the same way I don't know how to hit something with a sledge hammer and avoid the sledge hammer taking a massive absorption of shock. I had a fairly muscled up physique from boxing a lone. back muscles that look like a boxer's back muscles. from punching stuff. So I am linking some good shots, some-how.
To be honest I have also snapped a knuckle in half, the second knuckle. through a large glove and boxing wraps through hitting with a fully connected left hook on the bag. I realize the primary reason it broke was that I landed on that knuckle, and not the knuckle next to the pinky, I realize you want to distribute force over those three knuckles and not onto 1 knuckle, never the less, were I to connect with extreme speed, fast/hard enough to snap a knuckle clean in half. Aha, I will be cracking someone's face bone, esp without a glove. (also my knuckle healed fine. it doesn't hurt to smash stuff with. it healed larger and denser a little flatter. (some-what lucky on that account) I couldn't upper-cut without pain for awhile. I did anyway though. healed well. again, this was a well structured left hook. close to the body, elbow would have hit if the fist would have missed type deal, good line-up, my wrist didn't give or buckle, etc. just a heavy-handed shot that I didn't distribute over 3 knuckles.
WwWhen I get a new heavy-bag I will put up some good videos of the punching bag swaying around, and when I hit it, a some-what thunderous clap being produced each time. I'm not great with my jabs, but I do hit pretty hard with some uppercuts and hooks. straight right as well sometimes.
