I've been wanting a heart rate monitor for EVER, but could never bring myself to spend the money on it. I finally bit the bullet.....and we had our first test run this morning at the gym. O.M.G....... i heart it. It has a band, but i don't even notice it during workouts (it goes right where your sports bra lands....under the girls!). It even links up with the machine so your heart rate is correct on it (those things are always so spaze-tastic). It beeps at you if your not in your target heart range (which is customized to you from your weight/height/sex).... and tells you how many calories you've burned. Now if it would just do my workouts for me!!!
