Runners have yet another tool to keep track of their soaring pulse rates while they exercise. The Scosche myTrek is an arm band with a bluetooth-enabled pulse monitor that'll send your workout stats to your iPhone or iPod touch.
When you hit the pavement, you'll wear your iOS device on one arm and the heart rate monitor on the other. The monitor will track your pulse rate, while the iPhone's GPS will track your workout distance and time. Combined, you'll get a nice summary of your daily workout.
And if you're one of those types who burns their ear drums with motivational music, the pulse monitor band even includes controls for your iPhone's music player. Comfort and convenience comes with a price tag — the myTrek pulse monitor costs a hefty $US130. [Scosche]
