What parts do you work out together?

So it all came back to me while I was at the gym today and I want to go back to working like this I think but I want to make sure I have the right combinations:
chest & tri-ceps
back & bi-ceps
legs & butt

stomach & cardio each time

Does that sound right? If it is, do you do 3 exercises for each body part?

Re: What parts do you work out together?

i do the splits that you mentioned, except for abs. i only do abs three times a week and never consecutive days. i was told that since they are muscles too, they need time to recover just like the others.

Re: What parts do you work out together?

Its good to mix up the body parts after a few wekks/months

Right now im doing:
leg, chest, tri
back, shoulders, bi

and like the above poster said, alternate abs
