Being 30+ switch to every 4,5,6 days in that rotation.
Usually
-back/chest-----Monday(1st) then Fri-(4th) then Wed(9th) then Tues(15th)
-Shoulders/arms-Tues(2nd) then Sat(5th) then Thur(10th) then Wed(16th)
Legs After Shoulders/arms SUNDAY(6th) and Thirs(17th)
Yoou need more recovery time as you get older!
If I was 20-25 would go every 4-5 days but workout would consist of 2 warm u sets of 20 then 15 and work the next 2-3 sets at 70%,80%,90% max!!
Roids speeds recovery time optimizing protein assimilation.
