Lately my performance decreased because I can do less reps with same weight. I also sleep bad – wake up to early or can not fall a sleep even thought I sleep bad previous night. For some time I was losing weight because I ate to little (not on purpose I thought it was enough).
Currently I train 3 times a week (ABABAB). 4 exercises, 4 sets of 10 reps + 10 minutes of cycling (quite taxing).
My question is what should I do in such case? Take a week off? Do half number of sets?
