Just out of curiosity, what do you think is more favorable?
Scenario a. Spending one day in the beginning of the week blasting shoulders, then spending one day at the end of the week blasting chest.
Scenario b. Doing half chest / half shoulders one day in the beginning of the week, and doing the second half chest / shoulders one day at the end of the week.
Assume that TOTAL weekly volume for both chest and shoulders is the same in both a and b scenarios. If you do that the question becomes about frequency.
Is doing all the work in one day then resting for 6 days better than doing half the work every 3 or 4 days?
Looking forward to your responses.
