i personally dont like training two muscle groups at one time. if im doin chest and tric then i'll finish one before i start the other. i would complete my chest work out then move on to tric.

im gonna give u my routine and u can compare it to urs and make changes as u like

mon - chest + tric
tue - legs + abs
wed - off
thu - back + traps
fri - shoulders + bic
sat - off
sun - off

i dont know about u but i dont like working out during the weekend, i like to have the weekend off.

i do skull crusher, arm extention, and dumbell kick backs for triceps, works real good. i also start wit an long cardio warm up, such as runnin or playin soccer.
