Funnily enough, I was watching a training video this weekend of the guy who runs my martial arts association, Peter Consterdine; and was amazed by how developed his calves were.
As he explained in the dvd he placed a lot of importance on ankle strength/integrity for competitive martial artists, and thus worked his calves a whole lot. This included lots of weighted work, along with straddle jumps, lots of skipping and various work on one's toes.
In the spirit of this, I am trying to up my calf work even more; just to see how it works out.
Again, I am coming from about the worst calf development/genetics/whatever, so it should be interesting to see the results.
