routine questions

[obadaveil82]

Just started going back to the gym and I wanted to ask if my routine is effective.

I'm planning on going 6 days a week splitting my upper body workouts to chest, abs, tris (push workouts) and back, shoulders biceps (pull workouts). I'm recovering from a knee injury so no leg workouts but I'm cycling and doing the treadmill to keep my legs active.

as far as routines go i'm doing 3 days of each muscle group alternating days. day one I'll do 3 sets of 12 reps. day 2 4 sets of 12 reps, and day 3 5 sets of 12 reps. I plan to increase the weight each week by 5 pounds.

the idea is to increase volume of reps before increasing weight. I read somewhere about this and thought it could be interesting to try. please let me know if you think a straight week of the same sets and reps would be better.

thanks!
