It even has pre-programmed workouts and comes with training software so you can customize how hard it will be on you, and can give you a “virtual partner” to race against. Has different modes for running or bicycling. You can also set alerts at different heart rates, to keep you in the “zone.” Efficient exercise – doesn’t get much better.
