With LIVEexercise's online workouts, exercisers get all the perks of not having to leave the house while working with a partner. Unlike typical exercise videos, all of these 3,000-plus online workouts are led by instructors who guide you as you're watching. Users can also interact with their trainers via Twitter. The variety of classes caters to all ages and types of fitness pursuers, from first-time exercisers to people trying to lose weight or doing sport-specific training. LIVE episodes are available in real time and on demand, with new ones added each week covering cardio, yoga, kickboxing, Pilates, and muscle-building classes. There are both equipment-free classes and courses that utilize resistance bands, free weights, kettlebells, and treadmills. The workouts can be viewed on a number of devices, including PC, Mac, smart phones, and Roku.
