? on a new workout routine...

ummmmmm...what is a good workout plan to gain MASS!?!?

Now I am on a 3 day on, 1 day off routine
day 1
back and chest
day 2
bi's and tri's (occasional forearms)
day 3
shoulders and legs(calves as well)
day 4 REST

then repeat

It doesn't look bad, but I only do one bodypart per day so it gets all my attention and it allows me to be more intense. I say that because say if I do chest and back on the same day I might not be able to do enough for back because I am tired from chest. This is what I do:
day1-back and bi's
day2-chest
day3-shoulders
day4-tri's and bi's (bi's depending on how I feel)
day 5-legs
day6+7-rest
This allows me to put my full attention into each bodypart and allows me to prioritize my weak parts.

Chest and back in the same day?? How the hell do you do that?? After deads and Tbar rows, and some lat exer., I'm ready for my protein shake.

Working chest indirectly involves triceps...and working back indirectly trains your biceps....AND forearms. You need a few days to rest those muscles to have effective recoop. time.
Then shoulders the day after?? That's triceps three days in a row. :no:

This is what mine looks like.

Day 1: Back, Abs
Day 2: Chest, Tris
Day 3: Bi's, traps
Day 4: Legs,abs
Day 5 off
Day 6: Shoulders, calves
Day 7 off

You see, every muscle has proper rest before it is worked again.I'm always fresh and always ready to go.

BTW...I recently JUST changed to this split...bout two-three weeks ago, and i'M LOVING IT.

thanks...i might follow these =)

chest bi's
legs
rest
shoulders tris
back-traps
rest

i do abs every second work out
this way you get tris and bis worked twice in the week because back and bi
and tri and chest so its split up nicely
