$379.99 for ProForm Comfort Stride Elliptical ($999.99 List Price)

The no-nonsense voice of celebrity trainer Jillian Michaels—famous for her tough-as-nails training methods on _The Biggest Loser_—comes barking through the 2-inch speakers of ProForm's Comfort Stride elliptical. The elliptical comes with an iFit workout card that houses eight weeks of weight-loss workouts featuring Michaels's audio coaching. It's just one of the machine's tech-savvy features, which also include a workout fan, a dual-grip EKG heart-rate monitor, and a dozen built-in workout apps. The blue-tinted display clues users in on their speed, time, distance, and more. The inertia-enhanced flywheel spins quietly with Silent Magnetic Resistance technology so even cat burglars can use the machine without causing too much of a ruckus.
