If you're a jogger and want to keep track of your pulse rate, you now have an option other than a bulky pulse-monitoring watch. Say hello to the Pulse Ring. It's an absolutely tiny pulse monitor, fitting over your index finger and letting you wear your normal watch rather than having to swap out when you get ready to exercise.

Heck, this thing is so small you can wear it all the time. Aren't you interested in how fast your pulse is racing in non-workout environments? You can see how that first date is going, or how much that scary movie is affecting you. Start your own trend! Just make sure to give me credit when it sweeps the nation. — Adam Frucci
