I’ve begun doing very strict reps for more bodybuilding focus (previously did more strength 3-5 reps) but one thing I notice is I have difficulty keeping even reps across sets particularly with smaller lifts (curls, etc). For example, I pick a weight and go for something like 8 reps. After this first set I usually barely feel a burn and I’m like ‘darn, I picked way to light a weight, I could easily keep going’. But then I do my second set and I’m like ‘holy shit, I’m burning like crazy by the end’ and struggle a bit on the last rep. Then on the third rep I start to fail to make all 8 reps and get less and less each time.
So I’m unclear what to do in this case. Was my weight too high cause the first set was a breeze or too low because I couldn’t finish out the last sets? Does this indicate this exercise could use a different rep scheme or that I should be changing weights across sets (ie drop sets)? Should my goal be to pick a weight that makes me burn/struggle at the end of the first set?
