Well. If you like a torso limb split its fine. Personally (dont get offended) i find them retarted. You CANT take your biceps TOTALLY out of a back movement. Same with triceps and chest. So you will halfway work bis and tris on day 1 with chest and back. Then immediately hit them the next day on their own exercises. Then hit them the next day when u go back to chest and back. Too much. I personally would suggest (idk how many days per week u wanna lift but we'll assume 4) chest/back, legs, bis/tris, shoulders. You well ever so slightly hit tris a little on shoulders day. But not near as much as on chest. But either way, unless youre VERY large and built already (i mean like 230 and LEAN) , you dont need an arm day or necessarily work opposing muscle groups. Much better suited killing each group one day a week with compound stuff. Real high volume. Pretty heavy on most. Would be very beneficial.
