The Garmin HRM-Fit heart rate monitor only launched last year, but it's already on offer at Amazon. Right now, you can pick it up for only £136.03, which is a saving of 15% off the list price and the first deal we've ever seen.
The HRM-Fit is Garmin's first heart rate monitor designed specifically for women. Rather than requiring an elasticated band that goes all the way around your chest, it simply clips onto your sports bra, minimizing hassle and ensuring it stays in the right place. It's much less hassle, and using the clothing you're already wearing makes a lot of sense.
