Errata: Upon review, it looks like my Iggy Pop celebrity sighting was false. He was in town and I thought it reasonable to believe that he would have a gym membership that would allow him to workout in most cities that he would visit on the road, but this apparently isn’t the case. From a Blender interview:
Q: What’s your workout regimen?
A: I do about 40 minutes a day of qi gong, the fundamental exercises of tai chi. It looks like nothing, but if you learn from somebody who knows the shit, it’s really hard. Or I’ll swim about 200 yards in a pool, just to get a little bulk. I’m about 140 pounds, but I was a big boy when I graduated high school — 160 pounds. Singers look funny at 160, unless you’re in Lynyrd Skynyrd.
He confirms the qi gong, sex, and swimming regimen in this radio interview with Terry Gross.
