The 5-day rotating split... Feedback?

[TheRuffian]

For me I have always found 5-day splits to work best for me. For some reason spending an entire session crushing a single muscle group nets my best results. Traditionally my routine looks like this:

M: Legs
T: Chest
W: Back
T: Shoulders
F: Arms
S/S: Off

But this week I thought back to something I read about before on another board like a year ago which was a variation on the 5-day split. Well, actually it was a 4-day split with the first day repeated on the fifth, then rotated the following week. So something like this:

== WEEK 1 ==
M: Legs
T: Chest / Triceps
W: Back / Biceps
T: Shoulders
F: Legs
S/S: Off

== WEEK 2 ==
M: Chest / Triceps
T: Back / Biceps
W: Shoulders
T: Legs
F: Chest / Triceps
S/S: Off

== WEEK 3 ==
M: Back / Biceps
T: Shoulders
W: Legs
T: Chest / Triceps
F: Back / Biceps
S/S: Off

Etc... Etc...

I don't remember what this is called, or if it even has a particular name, but it looks like something I might give a try when I start my next cycle. The reason I like it is because you get to hit a group twice per week, but not on a regular occurrence, at least not a weekly occurrence. However, on the downside I don't really like how the days are always switching up... but then again that could be a bonus.

What do you think of this? Ever tried it or something similar?

Cheers!

It's a good split but try bi's on your chest day and move legs between chest and back

I've never tried it but i dont see anything wrong with it.

Assuming you are rested enough, a second day will not hurt you
