I`m here to motivate you Vince! One question my friend, why are you only training arms?
Well, I won't take credit but he has been boasting for sometime now, years actually, about his DOMS theory. I've always called him out that he has no proof. Not on him or anybody us. Though he doesn't want to admit it, as he feels age is no barrier, I believe it is a very daunting task to try to undergo a full body Casey Viator type transformation. I'm a lot younger than he is but I'm still old. And though I've been training consistently doing something like legs, squatting with weights on you shoulders and doing it like you mean it, really takes it toll. I can only imagine what it would be like for someone idle for many years. So I suggested to just take a single muscle group, one not so systemically taxing, like arms, and see where it takes you.
My belief and hope is that when you see progress you will expand to other muscle groups. The worse that can happen is that he will not achieve his circa 1970s condition but maybe it will get him back in the weight room. It's win/win for him.
Team Basile!
