The smartest way to better fitness, the Polar FT60G1 men's heart rate monitor watch helps you stay motivated & improve your conditioning. The FT60G1--which comes with a G1 GPS sensor that measures your speed & distance during outdoor sports--works by first checking your daily condition, & then guiding you to the ideal training intensity for your age & fitness level. Knowing your heart rate not only helps you reach your personal fitness goal, but also improves your physical condition in general, as it's vitally important to train at the appropriate intensity level. If you exercise too hard, you may quit before you reach the real benefit, but if you work out too leisurely, you'll struggle to lose weight at all. The FT60G1 helps overcome these problems by encouraging you to map out a complete fitness routine.
