“Train harder than last time and I’ll rest when I’m dead!” So, if you are an athlete you have to train to improve and the more quality training you do that you can recover from the better. People often think this means more is always more. The key points here are quality and recoverable. It is quality over quantity first. What does the research show us on this? Does strength training fatigue impair motor learning? This really looks at whether training too hard too often and not being recovered causes our training quality to suffer or not.
