One of the key changes in sports over the last few decades has been the advances in strength and conditioning. The Iowa Wrestling Blog gave us some insight into how the Hawkeyes are getting the job done with Travis Rutt as their strength coach.
Wrestling is very unique in that the goal is not put on a lot of weight, but to get stronger.
As someone that has studied the science of strength and conditioning, I can say Rutt is right on with the goals of strength training for wrestling to be gaining strength without the mass. It is different than most other sports.
