Chris Korfist Quotes

“Every piece of equipment is a tool. It’s how you use the tool, and what you get out of that tool is what’s really important.”

“When your body’s organized in a safe way, you can put more power out.”

“Pure power development, I don’t think there’s much better than a safety bar squat.”

“Most of our brain goes toward our hands and feet. And what we’ve done in the weight room is we’ve got a one inch bar that we grab all the time, and that’s what we get strong at. But when we sprint, there’s different hand positions.”

“That turnover is really what starts to separate the elite from the really good.”

“I don’t give running cues. My running cue is push as hard as you can off your back leg when you start and then race.”

“I don’t want to override what their brain knows subconsciously more about their body than I know.”

“I think, first of all, an understanding with your athletes as to why we’re doing the workout. Because I think if you can explain to them why we’re doing something, there’s going to be more of a buy-in.”
