4 Day Split

I am currently training 5 days a week but I'm struggling to recover.

Split look like

Push, Legs, Rest, Pull, Push, Rest, Pull

All programming is similar to AJs (top set back off approach)

I prefer my splits to run over a 7 day cycle so I have set days of the week for set sessiom (for example Monday is always Push) this is the only way I can program due to work commits so an 8 day Split would not work for me.

I'm thinking of going down to 4 days per week

Would Push, legs, Rest, Pull, Rest, upper, Rest be a good idea for 4 days per week?
