"It's the perfect way to kickstart a fitness regimen and diet," Bree Gotsdiner, Director of Media Relations for Fitpacking, told me. "And to learn portion control." Portion control is important, since hikes run between one to two weeks, depending on the trail, and you only eat what you can carry with you.

The guided hikes are rated on a scale of 1 to 4 stars - 1 star is the easiest, such as a hike through Olympic National Park in Washington, with 4 being the most challenging, a 2-week hike through Yosemite National Park, for example. That way, even experienced and fit hikers can get a great outdoor workout. (And if you're faster than the rest of the group, Bree, Steve, or one of the other guides, will lead you through some exercise like pushup contests to keep your heart pumping.)
