Pulse Boot Camp, Bothell

It may seem counterintuitive to up your energy by expending it at boot camp, but Coach Cassie knows better. The fitness instructor creates outdoor boot-camp routines that not only exhilarate, but also burn calories and tone muscles—what she calls Pulse Boot Camp. It's a fitting name since her mash-up of strength training, running, core work, and other exercises gets pulses racing.
