Morning Glory: One of the biggest impediments to morning exercise is that groggy, I-can't-get-out-of-bed feeling. The Sleeptracker is an ingenious little wristwatch-like alarm that monitors your sleep cycles and wakes you -- as close as possible to the time when you need to get up -- when you're almost awake anyway, not deep in slumber. $149 at sleeptracker.com, 800-617-4509
