Bowflex, the company best known for its all-in-one home-exercise machines, is showing off a pair of “smart dumbbells,” which log your weight lifting sessions, and also use sensors to detect if you’re moving your arms too fast (bad form, dudes). The SmartTech 560 dumbbells, as they’re called, then send that data to an Android or iOS app over Bluetooth. Even then, there’s a display on the weights, so you can glance at some of this info right there. Once you’re in the app, you can view 70-plus video tutorials, courtesy of MyFitnessPal, as well as participate in a six-week training challenge.
Additionally, the dumbbells use Bowflex’s existing SelectTech technology to add or subtract weight, using the cradle you see in that photo above. All told, the weights can shift between two and 90 pounds of heft, so you can use the set of dumbbells for your squats, lunges and bicep curls. (Fun fact: The company’s technology is already used in gyms, where you can pick up a weight and not worry about whether all the 10-pound dumbbells are already taken.) No word on an exact release date, except that the company expects them to be on sale before Christmas.
