opinion on chest twice a week split
My chest is by far my lagging body part and want to try twice a week to see if that helps progress it along. I'm not 100% sure on how the split should look without overtraining shoulders and tri's but here is what I had in mind:

Day 1: Chest
Day 2: Back
Day 3: Shoulders/Abs
Day 4: Off
Day 5: Chest
Day 6: Arms/ Abs
Day 7: Off

I know I dont have legs in there but I am currently working on an advanced 5 day Marine Corps running program so they are being hit.
