I've been training for 5 months now. And started an actual workout plan 2 months ago. I'm doing 5x5 ICF but I keep adding in extra reps in between sets and some extra sets aswell. Should I do this? Or just stick to the workout plan? Every time I don't add in an extra set I feel as though I'll get fat because I've burned less calories. I'm supposed to do 29 sets, but I do 39 sets instead per workout.
