If you're not in on the latest celebrity workout craze — spinning at SoulCycle — then you're missing out. Jake Gyllenhaal gets his sweat on at an NYC studio, while Katie Holmes, Lena Dunham, and other stars have been known to hop on a bike for a candlelit class or two. Now you can give the gift of fitness (at home!) with the SoulCycle bike ($2,200).
