What is overall power? Have a look at the attached pic of Ronald Rauhe. His legs look pretty pathetic (mine are stronger and I bet yours too) but his track record in sprint kayaking is more than impressive.
Crossfit haters call this multitude 'randomness'. I'm not yet a Crossfit hater (but I might become one ) Nevertheless I think it makes more sense to set up a sport specific weight training program.
Yes, it will make you a better Crossfit athlete. So if you want to take part in the Crossfit games it is the program of choice. But it does not automatically make you a better sprint kayaker, cyclist or runner.
Seriously Coach? Endurance training is that easy? and what's a very high level? (anaerobic threshold, VOmax,...???)
Obviously something is missing in this sentence.
and not the beitallandjackofalltrades Crossfit program!!!
Besides the fact that we are drifting away from the original question of the OP. He was worried about his increase of muscle mass. And there was this dude, what's his name...., yep, Greg Glassman (founder of Crossfit), who proclaimed a hierarchy of training for mass from greater to lesser efficacy:
1. Bodybuilding on steroids
2. CrossFitting on steroids
3. CrossFitting without steroids
4. Bodybuilding without steroids
And you Coach recommend this training that will make him grow even more than bodybuilding training and that though the Op wants to stay small.
Or does your experience tell you that Crossfit doesn't lead to growth of muscle?
So don't be personally offended (or be if you prefer it that way) but I simply can't hear anymore that Crossfit is the 'end all be all' solution and especially not from a coach (because you should know better)
