So, I've been unable to lift for a month due to speculative tendinitis and 2 nasty weeks of school work. Prior to that I was lifting 3x a week and had just made a push for my workout set from 290-300 5x5 on bench when I started having issues. Today is my first available day back, and I already can tell that I'm weaker. Should I start aim for 80% of where I was and slowly build? Or just try to do what I can? for my whole workout?
