Suunto M5
Best for: The minimalist trainer
Details: Unless you want to spring for the optional pedometer ($100) or GPS pod ($170), the M5 tracks only time and heart rate — and isn’t so good at the latter because of its loose chest strap. “It unclipped every time I touched the transmitter,” Lovato said. But he liked the M5’s sleek looks, as well as Suunto’s website, which lets you compare your workouts with other people’s for bragging rights. [$210; suunto.com]
