Good Post, Vince. I wish you well.
As far as hard training goes, I tried it. I f**ked up my knee, and pulled my hammies 4 times (right once, left 3 times). I realized that I don't need to kill myself for martial arts. It's all in the technique.
For the breaking question, like I said above, it's all in the technique. If you work on a punch, for example. Make sure you punch correctly (first two knuckles, ect). You don't need to punch something 100 times to do that. Work on it slow motion and work on form. Then use a punching bag to see if you are doing it right. If your hand hurts, you did it wrong
When you punch the bag, look at your hand. If the last two knuckles are slightly red instead of the first two, you did it wrong. This goes with any technique. There's different ways to know if you are doing a technique right.
When you break, think "through the board," too. If you stop at the board, you won't break it. Watch your hand mentally go through the board before you break. It helped me when I first started breaking
And don't forget to hit with the first two knuckles or it will hurt
I never did that "hit gravel" or kick the tree crap, and I am a breaking fool
And I still have the "girly figure" to boot
I heard that I kick like a horse, too (power that is) :shrug:
