Ryry - according to the scenario you present, Collins went his entire career without lifting, then started to fade in his 30s after what was already a long career for a sprinter. Then he started lifting weights, and was able to get back to his prime, and even better than ever. So, like, does he regret not lifting earlier now? In that scenario, it seems like a colossal mistake on his part, because it must be gaining him full tenths of a second over what he would otherwise be running now.
As I keep saying, I don't find it totally implausible, but I just am a little skeptical that somebody after 15 or more years as a pro athlete suddenly discovers the virtues of hard work. Collins' career trajectory reminds me a little bit of a different type of athlete - Roger Clemens. I pasted Clemens' career won-loss record below. It's like, he has a normal, really good career, starts to go into inevitable decline after a decade or so (he had an unremarkable 40-39 record from 1993 to 1996), then at age 33 or so, has a remarkable revival and pitches great for almost another decade.
How did Clemens explain his revival? this is from

:
“Grueling workouts,” we were told, a canard that Clemens repeated last night to explain his remarkable turnaround, as if all that kept Sandy Koufax from 25 years of dominance were a few more pushups.
