[SuperMate]

per muscle group

i know how many REPS in an exercise, but how many sets should i be doin

today was bacc/bi days and i did 18 sets in all

3 chinups
3 barbell rows
3 barbell shrugs
3 dumbell curls (pyramids)
3 dumbell shrugs (pyramids)
3 "twenty-ones" barbell curls

on shoulder day id do about 12 sets

on pec day id do like 8, same for triceps

what i also want to know iss how many sets for the abs ( i do 8 in all, 4 in a lower ab exercise and 4 in an upper ab exercise, not sure if 8 sets is enough)

Do as many as you can before you get tired...Your body will tell you.

I never stop a workout till my body tells me to.

most consider 20+ sets as overtraining, but everybody is different. it also depends how many days a week you workout. if you workout 3 days a week, you might be able to get away with 20sets+ for each gym session, but if you workout bodyparts seperatly then 20 sets should not be exceeded on a regular basis.
