Tjv1156, I just finished that exact regimen at Sloan in Commack with Dr Barsky.
I went into the weights very vigorously but found , as you did, that my old strength just wasn’t there.
I dropped 10 lbs from the barbell, 5 lbs from the dumbells and was able to do the same amount of reps.
Same with the treadmill and other aerobics. If you can’t do what you once did, don’t force it! Drop a level or two, or shorten your duration or distance.
The idea is to be able to exercise somewhat vigorously during your ADT treatment. You don’t want to get discouraged to the point where you just give up and do nothing.
Hang in there, it sucks but goes quicker than you think. I’m 2 full months off of Orgovyx and feeling stronger and more energized by the day.
