In a different life, Rollins would've been a cyclist

Hank lifts weights. Here's why:

"The Iron never lies to you. You can walk outside and listen to all kinds of talk, get told that you're a god or a total bastard. The Iron will always kick you the real deal. The Iron is the great reference point, the all-knowing perspective giver. Always there like a beacon in the pitch black. I have found the Iron to be my greatest friend. It never freaks out on me, never runs. Friends may come and go. But two hundred pounds is always two hundred pounds." 

I used to lift a lot of weight. Well, I used to lift weights a lot. But I think cycling is just as demanding. Substitute "the Road" or "the Wheel" or "the Pack" or "the Climb" for Henry's  "the Iron." You'll understand why.
