I am currently going through ADT and I do a combo of resistance and aerobic training. The only side effect to date has been hot flashes from time to time, nothing else to report. I lift M W and F accompanied by aerobics, and then do aerobics T T S and take Sundays off. You may experience weakness and occasional tiredness which a nap will help. Best of luck. I have dropped my PSA from 108 to .1 in six weeks. Also, watched my diet, eating fruits, vegetables, and fish, excluding processed foods, seed oils, sugar, and dairy products. Best of luck! BTW I am 76.
