Hypothetically, can a 41 year old QB do anything to meaningfully improve arm strength in the offseason? If strength is declining, could you combat that by doubling down on strength building workouts? Or is the arm like a tire, where the tread gets worn down and it’s done.

I mean, you have all of these baseball players who became home run kings when they were well into their thirties. Of course, they used steroids, but theoretically one could accomplish naturally what one could accomplish with steroids, given enough time and the right training regimen. Right?

And, hypothetically, you don’t need the 41-year-old QB to launch it 50 yards downfield 12 times a game. You just need enough steam to keep defenses honest.
