Have you ever had one of those days at the gym where you just couldn't perform and there is no reason as to why? I can't work out what happened with my strength training today. Usually I clean and press 76kg for 7 reps. Today I couldn't even do one. After much frustration I managed to clear 4 reps but not even press the 4th rep. I felt fine today, I just can't work out what happened. Has this happened to anyone else?
