Firstly...you really arent going to do half as well on 3 meals a day as you would 5 or 6. Just buy yourself a whey shake and a shaker and make a couple a day. It's really NOT a hassle. Dont be so lazy now.

Also, your routine could do with a lot of work.

Firstly, give legs its own day. It's the biggest muscle group. So on a leg day you could for instance do: squats, lunges, hamstring curls and then do some core work after (i.e. hyperextensions or sit ups).

I see youre doing chest on sunday, then triceps on monday. That wont work as chest exercises work the triceps so they'll be dead the next day. The same applies to biceps and back. Back exercises hit the biceps HARD so doing biceps 2 days before doesnt make much sense.

If you really do insist on this 4-day seperate body-part split, then do back & biceps, shoulders & forearms, your leg day, then chest and tris.
Personally, I prefer the lower/upper body splits and I know a lot of strength coaches do too. But whatever works for you.

Also, make sure to keep to compound exercises mostly. I.e. Squats, bench press, deadlift, chin ups, rows, lunges etc
Do whatever isolation exercises you feel necessary after the compounds.

I've got an exceptional program from a GREAT performance coach, but i cant post the url on here, so if you want it, private me (if that's even possible on these forums)
