Hiking trails are good for more than a challenging outdoor walk. The uneven terrain forces the body to use more stabilizing muscles in the abdominals and back, which improves balance and strengthens the core. Sprints or walking fast uphill puts you into an anaerobic zone, which taxes the muscles and benefits the cardiovascular system.
We took to some trails near Jet Propulsion Laboratory in the San Gabriel Mountains foothills with Keli Roberts ( www.keliroberts.com), trainer and former IDEA Health & Fitness Assn. international instructor of the year. She says she regularly uses this area for workouts but the exercises she demonstrated are perfectly suited to countless basic hiking trails found throughout Southern California. Though beginners can easily tackle these moves, it's important to pay attention to the modifications and make sure the terrain isn't excessively rocky or craggy, because it's easy to slip on loose rocks and dirt. Always keep an eye on the ground while moving. And stay focused on the task at hand. Take in the view on a break -- and gaze at the rugged hillsides, yucca plants and wildlife when stopped, not during an exercise that requires concentration.
First, warm up: Walk briskly, run or run-walk for 15 minutes, increasing speed as you go. Then try:

Hill skip repeats
The hill skip is an exaggerated skipping movement in which the knee and opposite arm drive up as high as possible during the jumping portion. Go for height, not distance, Roberts says. Done on an incline, the skip is a plyometric (high-intensity, explosive motion) and anaerobic move that develops strength and speed. It also targets the calves, glutes, hamstrings and quads, and some shoulder and latissimus dorsi (lat) muscles. Core muscles are also affected, as the body strives for balance.
"This helps develop the ability to lift yourself up," Roberts says. "It makes running or playing soccer or going up a flight of stairs much easier. It's like putting steroids in your hike."
How many: Five to 10 repetitions, with about a minute-long walk down the hill inbetween to recover.

Uphill walking lunges
Take walking lunges out of the gym and put them on a hill and suddenly this already challenging exercise becomes super-tough. "It's a complete exercise for the lower body," Roberts says, targeting hamstrings, quads, glutes and inner thighs. It conditions the ankles and feet when the body tries to right itself on an uneven surface.
