These weights actually keep up with the calories that you burn. How neat is that. Along with that, it also helps to :
communicates with your smartphone via USB
collecting and recording your activity
storing it as an exercise regime which can be sent to your computer
These weights also have digital like rings on the ends that start turning red as you reach 400 calories. I bet this would give some people great motivation.
