I rotate the hypertrophy 2 and strength v2.3 over amd over as those are the only templates i possess at the moment. Given that i just repeat them would it be appropriate to keep the highest prescibed gpp dose throughout both templates or is it better to reduce the volume as stated in the program and ramp it back up again? Also, would it be appropriate to add a set or two to all of the other work as well e.g. main amd supplemental lifts? Thanks!
Yes, you can keep the higher dose GPP.
I can’t give a strong recommendation for your second question based on this information alone, unfortunately, but I wouldn’t just add sets for the sake of it unless there was a good reason to do so.
