Polar H7 Hr M Xxl
Great weight loss and reduced injury
I love the Polar H7 and the android app that goes with it. Heart rate training is a great way to lose weight and improve fitness, also reduced the risk of injury, Polar assess the impact of each training session and estimate when and at what level it is safe to train again. I purchased this to replace an older model, experiencing chaffing with the newly designed strap.
