Trained biceps n back yesterday.. for biceps with little rest I could barely lift the same weight I lifted during my first set (15kg) during my second, had to drop the weight to 10kg straight away. By the 4th set I was struggling to lift 5kg..
I then struggled through some hammer curls... do I do one set of normal curls, 1 set of hammer and alternate between them, or do all of the one specific exercise at once?
Btw not sure how heavy other people can lift but I've only started a couple of months ago
