We've all been there: You've trained for a few years and know how to get stronger. You set your sights on a new PR and carefully plan your training. You get tired, sore and stiff but never miss a session. You follow your own (and everyone else's) good advice and take a week off. When max day finally arrives you turn your music up loud, load the bar and attack...only to get stapled by the same weight you tried weeks before.
