a couple days ago i made an order on amazon for a watch that keeps track of your heart rate and the calories you burn during your workouts and it came in!! for only $25 i think it was a good investment. my sister has one like it, but she has to strap a heart rate monitor around her in order for it to work, and mine [they were both the same price] only requires you to hold the silver ring for a couple seconds to record your heart rate.
the screen where the time is is a touch screen where you can switch between the time, your user info [male/female, hight, weight, age, etc. to make sure its readings are accurate], as well as memory from previous workouts! i cant wait to take it to the gym later and test it out.
for those of you that are curious, it is a Gaiam Oregon Scientific watch called the G2 Fitness Trainer and you can find it on amazon as well as the Oregon Scientific website.
ill be sure to let everyone know how it works!
I want one too! Those look so neat.
