In all this talk about traditional TKD I started looking at how I came up training. We used to work the heavy beg for hands but especially for our sidekicks and back kicks. A friend of mine on FB had a great photo of the bag going horizontal. A great measure of power. In class I also like having a holder use the larger square pad and the attacker hitting it real time hard. I think this last drill really teaches effective striking. I think the heavy bag also lets them know quickly if its right, wrong or has any or a lot of power. Anyone else still work the bag? Dave O.
