Take It Outside: What You Need to Hike, Bike, and Run Trails

Hike Your Booty Off

Taking your walk on the 

wild side will help you

 burn nearly twice as many 

calories per hour as 

pavement -- and give your

 mind a little TLC. A 

study in Environmental 

Science & Technology shows 

that exercising in nature 

can boost your mood and your energy level.
