I'm in a 3 week 10x3 routine where I increase reps by 1 each week. Every 4th week, I increase the weight slightly and drop back to 10x3. So far, I've been able to keep this pace for 9 weeks with one exception this last go-round. Week 1 of bicep curl was no problem, Week 2 was tough, and Week 3 I could not lift the weight past halfway after set 5.
Should I continue and make a slight increase in weight and start back at 3 reps. Or should I continue 5 reps until I can perform all 10 sets?
