How many days rest do you take?

[was140]

I currently WO Mon-Thurs. Off Fri-Sun. due to work.

I currently do
Mon chest/tris
tues legs/shoulders
wed back/bis
Thurs chest/tris again, doing different lifts than Monday. I do aprox 4 excercises per group 12,12,10

Is that enough time between Mon-Thursday to recover or should I

Mon chest
Tues Legs/shoulders
Wed Tris
Thurs back/bis

Doing the same amount of reps but adding a couple more lifts more like
Mon do 6-7 for chest or would that be overtraining?

2 days: Wednesday and Saturday.

If you're progressing, than your routine is sufficient. If not, then rest may be an issue, but don't forget to rule out other things. It's just as easy to undertrain, as to overtrain.

I do a full body workout, with around 48 hours rest between each one, so my off days vary each week...

I just started working out again and am doing Mon through Fri with Sat and Sun off.

2 days off a week (one of these days is light cardio) I don't have a fixed week so those days off could be any day of the week. I always take a day off after legs however.
