Coach Staley Please

Coach,
Can you give an idea of where to begin with volume. For example, I’d considered using 2PR Zones of 15 minutes and focusing as such for upper body specialization:

Two 15 min PR Zones:
PR 1: Military presses w/ chins or pulldowns

Two 10 min PR Zones
PR 2: Biceps and Triceps.

I’d do these on Tuesday and Saturday, while using Thursday as a maintenance for legs and chest which grow easily for me. This would afford the opportunity to hit an EDT upper body cyle twice per week.

thanks,
DH
