Yes, I have read the other kick balance thread but I've tried the wall side kick, repeating slowly many many times, and the other drills but my balance issues don't arrive until I'm recovering from a hard kick, not initiating it.
I'm about 5'9" and 150 lbs,around 4% body fat. I've been in various sports such as football and track, so I'm pretty confident in my overall muscle strength despite my light weight. Especially my legs, I ran sprints in track so I know they are fairly strong and quick. I'm also confident in the strength of my abs, back, and obliques.
I have a background in tae kwon do, karate and muay thai, but I never took classes for more than a couple months at a time. Whenever I'm repeating a muay thai round kick or a TKD back kick, I never land gracefully. I'm always taking a step to the side to re-balance myself. Even if I exaggerate lowering my center of gravity, as soon as I put power into a kick it's like the recoil of my own move throws me off balance. I do emphasize hitting completely through a target, but I still believe I should be able to control my own body posture throughout the move.
I have noticed that on the bottom of my feet, my weight distribution rockets to the side during a kick, and that is the direction my body moves towards. But I'm always keeping my heels off the floor and bouncing on the balls of my feet.
Here's an example of what happens, I'm standing in a typical TKD stance with my left foot forward. I twist my hips and initiate the back kick, and as soon as I "snap" the kick and tuck it back down, my new front foot(right) has to step off my center line towards the right. So how would I train to have a swift, graceful balance that lands on my center line after a kick without sacrificing power?
