[Riot Act]

I usually just lift 3-4 days a week with each day split into Chest/Biceps, Back/Triceps and Leg/Shuolders.

However, right now I'm going through a really rough time personally and I'm otherwise getting too swamped to fit in a proper lift each workout without it feeling rushed.

So, what I'm wondering is if I can change my split so that I work out more days a week but only hit one body part each day. For example:

Monday - Chest
Tuesday - Biceps
Wednesday - Rest
Thursday - Back
Friday - Triceps
Saturday - Rest
Sunday - Shoulders/Legs

Or perhaps I could lift 5 days straight and have the weekend off? I've actually seen guys use this routine but I always assumed it was incorrect or at the very least a bit counter-productive. For example:

Monday - Chest
Tuesday - Biceps
Wednesday - Back
Thursday - Triceps
Friday - Shoulders/Legs
Saturday - Rest
Sunday - Rest


Thanks for any help/advice.
