Busted Coverage has this photo, taken earlier in the week, of a cycling run-in with a certain former baseball player and huge man. Bonds is apparently spending part of his summer biking in the Rockies, and he looks...different.
For reference, the guy in green is 6-5, 185. Bonds appears to have lost some of the muscle from his playing days (though he's still all muscle), either through a new cycling exercise regime, a reduced diet, or some other lifestyle change. Of some sort.
Or maybe it's just the spandex.
