I said I thought I could still build muscle at my age and completely natural and without any supplements whatever. I am into the experiment now and completed my 4th arm workout today. Training only arms at the moment. Biceps and triceps supersets. Ending in 6 sets with the maximum resistance. Progressing rapidly which is almost scary! Mostly regaining some of my former size. I am confident I can get bigger arms than I have previouly had. Should be an interesting experiment. I will show you guys because I need a strong incentive to keep this training going. So far there is no hint of any diminished response to hypertrophy training. This is what I predicted for myself. I can't say it would be the same for everyone else. I won't even consider using any drugs or supplements. This is a purely natural experiment to show what is possible as one gets older.
