When the device ships this summer it will support five different workouts: running, weight training, cardio boxing, swimming, and biking. We had the opportunity to see the running and cardio boxing workouts in action, and walked away fairly impressed. With just the small sensor on a wristband, Moov was capable of letting us know our running form could use some work, and gave us tips on how to throw the perfect jab. The cardio boxing demo in particular felt a lot like other fitness games we've seen like Let's Dance, in that it suggested movements and then awarded points based on how well we were able to perform them. The difference of course, is Moov is handling all that with a watch and an iPad.

At launch, Moov will be iOS only, but an Android version is expected to follow three months later. The plan is to add support for more workouts over time, and sell Premium workouts as an additional purchase, similar to how you might buy a new title for your PlayStation. Other titles in the works include yoga and martial arts. Ultimately Moov will retail for $120. In order start production, the company is crowdfunding its initial run of devices, and offering a discount for early adopters -- $59 for one device, and $99 for two. Those who get their workout buddies to buy one as well can score $5 off the purchase price for each referral.
