Should I lower my volume to do more frequency

[chudgreycell]

I’ve been running ppl for a while doing 3 sets per movement but I’m switching to anterior posterior. Would it be beneficial to lower my volume to just 2 sets per exercise since I would have less time for recovery.
And how many days is most optimal before a rest day

Do 10-15 sets per muscle group weekly
