We’re back with MASScast episode 2 and we’re joined by Dr. Mike Zourdos to discuss several things which can impact your strength performance right now. In this episode we discuss the effect of mental stress on lifting performance, the effect of social media use on lifting performance, and post-activation potentiation, which is a tool where you can potentiate your back off sets’ performance with a heavy top set. What constitutes mental stress? How do you minimise the negative effects of mental stress when it can’t be avoided? What type of social media usage might be a bad idea before training? How can you set up your top sets in such a way to improve your volume performance in back off sets the most? Join us as we answer all these questions!
