Yesterday i did 4 sets of 10 reps of normal curles, and then another 4×10 hammer curles, and ended it with like 10 Dumbbell Concentration Curls.
By the end i felt like my bicep was at it's limit and i thought i reached "failure" so i stopped and continued my day but now(the next day) i feel fine, my biceps work just fine beside a faint "ache or fatigue" in my left biceps, had i took a 1 hour break i think i could've done like an extra 3×10 or 2×10, did i do it right or should i push my biceps harder? I tried to do some curles and i can do them fine, obviously i don't think i can get do4×10 today too but i can do like 2×10
