Bask in some vitamin D—and get a workout in, too! Here are some advantages of going outside for exercise.

IT’S CHALLENGING: Let’s face it, you don’t work out expecting it to be easy, you want a challenge—that’s where the results come in! Being outside in a changing environment with hills and other difficult terrain makes it a naturally good workout.

IT’S GOOD FOR THE MIND: Working out isn’t just good for your body, it’s good for your mind. When you’re outside getting exercise on a sunny day, this can do wonders for your mood and having a more positive outlook.

IT’S FREE: If you’re trying to stick to a budget and up your workout game, look no further than right out your window. To elevate it even further, look for hiking trails in your area by heading to AllTrails.com.
