If you've ever zoned out at the gym in the middle of a set and lost count, here's a solution that will let you zone out as much as you want. BowFlex's new SelectTech 560 smart dumbbells is proof that fitness tech is moving beyond wristbands. This set of two weights is considered "smart" because they allow you to adjust how much you lift from one to 60 pounds on each dumbbell, and, as you lift, the dumbbells automatically record every rep. When paired with a mobile app, the smart dumbbells let you "just lift" (literally, that's an in-app exercise) or follow lifting and exercise routines that incorporate the dumbbells.

While the SelectTech 560 sounds like a no-brainer for hardcore lifters who want to exercise at home without investing in an entire rack of weights, there are a few catches: that's 120 pounds of weight you'll have to get into your home, and the set costs $499. Check out the video above to see what I thought of the BowFlex smart dumbbells after I gave them a try.
