increasing weights

jonchao72 SG

when i increase the weight of my dumbell when doing for example, bicep curls, should i decrease the number of sets i do, decrease reps or both?

like i got comfortable with 10 sets of 10 reps with a 12.5 kilo one...

a few days later, i did 8 sets of 8 reps with a 15 kilo but my muscles didnt feel any strain on the next day..

so how?

Maybe can try increasing the weight further while keeping to 6~8 reps? Make sure form is correct though.

I haven't been doing bicep curls for a while... did only chin ups for biceps... or just hanging at the chinup bar with my arms at right angles to strain the biceps.
