Since I cant work my upper body from my shoulder injury, and I've neglected my legs most of the time, ive trained them maybe once a week, an I've been wanting my 6, I figured now would be a good time to concentrate on abs and legs, and get into the habit of training them for when i go back to the gym. What my idea is , is to focus on my legs once or twice a week, and my abs about three times a week. But my questions are:
1: If I'm trying to get my 6 showin, should I continue to eat my 6-7 meals a day? I know it raises your metabolism if you eat more, but the extra calories might not help too much if im not using them, i eat about 5-7 times a day.
2: I plan on doing cardio about 3 times a week, should I be doing more?
Please help me out with this, I'd rather work on something , then nothing

. Im 5'7 170 pounds, put on 40 pounds of bulk over summer.
