Training, diet, lifestyle, it’s all a damn mystery. Every decade a new commonly-accepted wisdom comes out. The only thing I’m fairly certain of is that you need water and sleep, and even that seems to be optional for the tougher specimens of our species (aka collegiate wrestlers).
Anyway, I read an interview recently with someone big (I think Fabio Gurgel) where he said that strength and conditioning is never better than mat time (drilling, positional sparring, competition training). However, he continued to make the argument that you still should do strength and conditioning to prevent burning out mentally.
I like that philosophy. Strength and conditioning is the thing you do to spice up your relationship with jiu jitsu. At the end of the day, technique will conquer all, and you won’t learn technique running on a treadmill. But we are not robots, and can’t do the hard boring thing every time. We need to do the fun things as well.
Epilogue: Have you ever written something full of contradictions, and at the end you are not sure you agree with any of it? Well that’s what this blog post is for me. But I think the internal conflict I have on the subject represents something: the fact that it’s not easy to design the perfect training regimen under the constraints of real life and real mind.
