Kick it up at notch! Take your fitness to next level! If your sweat equity is not producing the results that you desire, a way to measure your true performance intensity during workouts is a heart rate monitor. At a glance, you can determine if you are meeting your exercise goals. It displays the number of calories used and the percentage of maximum heart rate achieved during maximum exertion. A heart monitor is a great tool to push you to challenge yourself and help you get the best fitness bang.The Polar heart rate monitor is my favorite. It adds a little bling to my workout gear and makes me look like a real athlete while keeping me in my optimal workout zone!
