Tony Gentilcore is a co-founder of Cressey Sports Performance and trainer at his current gym, CORE. He talks with us about training at 80%, motivating clients and holding back when you're pushing too hard on your lifts. We also talk rehab as he's coming back from achilles heel repair surgery. Build a wider base in order to improve your 1RM. Don't test your strength, build it. Working hard doesn't always mean making the exercise harder.
