To the lifters here ...

Curious - tell me what muscle group split your regimen consists of. I'm pondering my options:

1- Chest n back, shoulders n arms, legs n abs (3 days)
2- Chest n biceps n rear delts, back n triceps n front delts, legs n abs (3 days)
3- Upper body, legs n abs (2 days)

I like short cycles (2 to 3 days at most) so that the gap between doing chest (for instance) and the next time doing chest is 2 to 3 days at most. Long gaps hurt my gains ... it's like my chest forgets how to lift what I lifted the previous time.
