This is my plan:
Mon: chest, back, triceps
This is okay if you follow a type of low volume training like DC, but its fairly complex, so you need to research it. Until then, if you're doing conventional lifts, back and chest together will not work well. With conventional lifting routines, after I'm done with back, all I want to do is hook up an IV and go to sleep, forget about doing chest.
Tues: Biceps, forearms, abs
You shouldn't be doing bis the day after back. Also, you're wasting a lifting day by just doing bis and forearms. You'll never grow doing this.
Wed: Off
Thursday: legs
Friday: Calves, abs
Same deal as your bicep day. Do calves with legs, don't waste a rest day with calves alone.
Sat: Off
Sun: Off
