Seriously, who came up with the name “Smart” Dumbbell? I still don’t know whether I love or hate that name, but I can definitely say I want the Bowflex SelectTech 560 Dumbbells for my smart home (or… smart gym). Bowflex is famous for its compact free weight setup, which is an obvious feature here. But what really makes this weight set special is the fact that it syncs to your phone through Bluetooth in order to count your sets and reps, give you workout advice, and much more. In just no time at all, you’ll be able to snap your phone clean in half when you didn’t meet your gains goal at the end of your session.
