Pops, you are feeling all those aches and pains because your are ancient and haven't trained much for years. Take my advice and forget weights and machines. Take the dog for a walk and after do some very light exercises with some latex rubber tubing. You should also lose some weight. You must be around 30 or 40 lbs overweight.
Although this advice you offered was not to me, I am only two years behind Vince, so it caught my attention.
While I don't mind being the age I am, your calling Vince "Pops" seems a bit rude unless you and he are close friends. Guys at the gym where I work out, don't call me Pops, they call me by my name, showing me the same respect they would anyone else.
Your advice is good advice for anyone who is not particularly fit or doesn't have a history which includes weight training. There is nothing wrong with walking the dog per se. However, if a fellow has weight trained most his life, why should he not do it until he dies? Sure, anyone who has taken a holiday from the gym should ease back into it. And perhaps the older one is the more careful they should be about this. But your suggestions come off as if one shouldn't train with weights at all after certain age and that is just wrong. There are fellows at my gym who still lift and they are close to eighty years old. Some of them look a heck of a lot better then some younger guys do.
Vince no doubt knows what his body can and cannot do. Sure, he is pushing himself just like most anyone does. If people stopped training just because they felt a little sore, no one would train more than one time in their life.
As for Vince's weight, he looks a bit chubby in those photos. However, I doubt you have the ability to determine just how much weight he should or shouldn't lose just by looking at a couple of photographs. So your suggestion that he lose 30 to 40 lbs. uncalled for.
I assume you are a younger person. It is somewhat amusing when younger folks act as if they know it all....especially to us older folks. Just remember, with any luck at all, you too will be sixty-nine someday. Perhaps all you'll be able to do is walk the dog and play around with rubber bands. That is entirely up to you.
