On the lighter side of fitness, Tom Cruise is reportedly doing a "grueling" 90-minute Pilates workout daily. Gossip writers are speculating that Cruise is doing the workout to keep wife Katie Holmes happy, though an unnamed source claims that the actor has been doing Pilates for years.

We do not profess to know why Tom is doing Pilates, but we laud him for it anyway. It is a great workout and as anyone who has seen Madonna can tell you, Pilates can keep an aging body looking good.
