I went home that night and did some research.
Turns out my friend wasn't telling me anything fringe. Grip strength peaks in most men around their late thirties.
After that, without deliberate resistance training, it declines every single year.
Studies out of the NIH have linked grip strength directly to long-term function, independence, and overall health as men age.
Not just opening jars.
Everything.
The ability to carry your own groceries at 70. To work on your own car at 75.
To pick up your grandchildren without hesitating. To shake someone's hand and feel solid doing it.
It all starts in the hands.
And the research was clear on one thing: the men who maintained their grip strength as they aged weren't doing anything complicated.
They weren't in the gym for hours. They weren't following elaborate programs.
They were applying resistance to their hands consistently. And they were increasing that resistance over time.
That was it.
The problem was finding the right tool.
Most grippers on the market are fixed resistance. You buy one at a set tension and that's what you get forever.
Either it's too easy and you plateau immediately, or it's too hard and you risk hurting yourself trying to force it.
I ordered three different ones. Two snapped within a month. One was so stiff I couldn't close it fully without my wrist screaming.
I was about to give up entirely when my physical therapist friend mentioned something called an adjustable progressive gripper.
Specifically, he mentioned PowerGrip.
"It's what I recommend to the tradesmen and veterans I work with," he said.
"Men who need their hands to actually work.
Not guys chasing a forearm pump at the gym."
That was enough for me. I ordered one.
