I had a chance to hear Mike Robertson speak a few times about training. I try to make it a point to make it to every Indy Performance Seminar. Mikes gym IFAST was named a top ten gym in the US by Mens health. Mike just put up a chance to watch his single leg training presentation on his blog for free! I drove down to Indy and payed money to watch. So while it's up on his sight for free, I suggest you go over and give it a watch. Mike is one of the top Strength Coaches in the US. Not only have I talked with him, one of my best friends trained under him while he competed. So I've got the inside and outside scoop so to speak. He'g good. Learn from him. Here is Mikes blog and the link you can watch the free video.
