muscle groups-1 or 2 times a week?

[mole351]

i've heard many people say you should only train each muscle group 1 time/week, and i've heard others say you can do it multiple times. what do you guys say? i guess it may depend on how may different exercises and how many sets are done with each muscle? here's my workout:

mon: chest: bench (4 sets), incline bench (3 sets), flyes (3 sets)
back: pullups, one-arm rows (4 sets), rev. pull downs (3
sets), cable rows (3 sets)

tues. cardio

wed: legs: squats (5 sets), leg extension (4 sets), Seated
leg curl (4 sets), lying leg curl (4 sets), calf raises (4 sets),
abs (multiple exercises)

thurs: cardio

fri: shoulders: overhead dumbell press (4 sets) front raises
(3 sets), side raises (3 sets)
tris: dumbell lying ext. (5 sets), close grip bench (3 sets),
tricep pushdown (3 sets)
bis: dumbell curls (5 sets), hammer curls (3 sets), preacher
curls (3 sets)

sat: cardio

sun: off

so what do you think? once or twice a week? also, please feel free to critique the workout (i.e.-should i add more exercises?) thanks!

its ok. However, Ive always disagreed with chest and back on the same day because they are big bodyparts to cover.

I would try: Monday Chest and tris
WEdnesday back and bis
Friday legs and shouldrez
