Spinning Teachers
13) WHO: Andrea Lawent

TITLE: Sergeant Spin
WHAT: The queen of the 40-minute stationary bike ride, Lawent plays hard rock music like Rage Against the Machine, Metallica and the Sex Pistols (a member of which is a regular at her classes) while she cruises the room and yells out commands.
CELEBRITY CLIENTELE: Christina Applegate, Jake Gyllenhaal, Jamie Kennedy, Anthony Kiedis, Melissa Joan Hart, Jodi Lyn O'Keefe, Melissa Rivers
CELEBRITY ENDORSEMENT: Applegate's been a Lawent devotee for so long that when she attends, she "leads" the class from a bike in the center of the room.
SECRET WEAPON: Lawent's attitude. "Look, I'm a single mom with two kids -- my frame of mind is very much based in reality," Lawent says. "It's not one of those classes where we say, 'Imagine you're on a country road.' No, we are working and people get results because they tap into a whole different place."
BUT CAN YOU GET IN? Sure, though it wouldn't hurt to sign up 24 hours in advance -- most of her classes fill up.
