Sento! You totally get me!
If your opponent stumbles, and leans in off-balance with his chin stuck out you have a brief instant to connect before he recovers/moves. You don't throw a straight right or a hook, you throw one of those kinda looping shots from waist height. You don't have time to move your feet, adjust your hips, then throw the punch. You just kinda "hop" into place, turn your hips, and throw all at once. You have to get your feet and body into position, as your fist is moving, but BEFORE you connect.
You land that powerful shot "through correct musculoskeletal alignment, sequencing of movement at the different joints of the body, and correct signaling of the agonistic muscles and relaxation of the correct antagonistic muscles."
Like Airtruth says, the wind-up has to be incredibly fast. To be really fast, the "wind-up" has to be short.
Watch some tape of young Tyson. He swings hard, but its more than that. He is always generating maximum power PRECISELY as he lands, not right before or right after, and guys heads bounce off his fist like kicking a basketball. Tyson said in his book he worked out in prison, but he really "lost his timing." He specifically called it timing, not power.
There is a similar "instant" in olympic weightlifting. After you "pull" the bar is weightless as it "flies" up. During this brief time, you go from driving everything up, to dropping your body underneath the bar. You reverse the way your body moves. Your "wind up" has to be really fast and short.
Now, as a lifter, its too late for me to go throw 10,000 one inch punches to develop this kind of coordination.
For you fighters, it would be silly to waste your gym time doing 10,000 power snatches.
It would even be silly for me to do the 10,000 power snatches. Only a short portion of that lift really creates the feeling we're after.
There must be some drills or exercises or lifts that maximize "white matter stimulation," which would lead me to be more powerful and explosive all around. I'd be better at ALL punches without practicing every specific punch, or a better lifter without practicing every specific lift.
Are you guys familiar with that move Eastern Fighters use where they kinda bounce around on their toes while pumping a barbell back and forth in front of themselves at shoulder level? Maximum bounce at the bottom, with barbell close paired with maximum tension at the top and the barbell at arms length. I saw Fedor and his brother doing it a few times, and they hit pretty hard.
I hope you guys don;t mind me, as a non-fighter, cluttering this place up.
