NOT A GYM RAT? HERE'S HOW TO GET STARTED ON AN OUTDOOR EXERCISE ROUTINE

Between the sweat smell, fluorescent lights and omnipresent television screens, April Herring has never connected with going to the gym.

Instead, she runs, bikes, hikes, plays tennis, pickleball and football - anything to get her exercise outside as often as possible.

"Fresh air, sunshine, the variety of the trees as the seasons change," said Herring, an administrator at Carroll Community College in North Maryland. "There's something about the energetic healing quality of nature."

The health benefits of spending time in nature have long been established, and exercise in general, of course, improves physical and mental well-being.

Combine the two and you double down on what adults need to stay healthy, said Debbie Rhea, professor in kinesiology at Texas Christian University.

"We've got to get outside. We've got to be active," Rhea said. "If we're going to live long lives, this is what it's about."

Getting started on an outdoor routine, however, might not be as easy as signing up for another gym membership. Here's how to get going.

START SIMPLE WITH WHAT YOU LIKE

If you haven't been active for a while, think back to the activities you enjoyed years ago, suggested Connie Sciolino, founder of the Alpine Training Center in Boulder, Colorado, a gym that trains athletes for outdoor mountain sports.

People who like occasionally hiking or biking should start building an aerobic base by taking progressively longer walks or rides. Once you're comfortably in the 35- to 45-minute range, start adding some intensity to build strength, she said.
