The last few years saw the launch of smart fitness equipment, including mirrors, bikes, and treadmills.

Peloton’s connected bike and subscription model have chipped away at popular rivals SoulCycle and Equinox by allowing bike owners to join live group classes from home. Last year, the company launched its Peloton Tread, a connected treadmill with a companion app that leads users through a variety of running and training classes.

The JaxJox Kettlebell Connect is a kettlebell set that tracks your movement using Bluetooth. Mirror is an interactive gym masquerading as—you guessed it—a full-length, wall-mounted mirror. A coach leads recorded or live classes and the mirror interface actively helps you adjust your form.

Meanwhile, Tonal is an interactive fitness mirror that comes with adjustable arms for resistance and weight training. The system will automatically detect your performance and increase or decrease the resistance accordingly during your workout.

The Hydrow Rower is a connected rowing machine with adjustable resistance levels and pre-recorded workouts. FightCamp Gym is a connected punching bag with corresponding classes accessible from iOS devices.
