If you know that you have the stamina to complete a hike, then your hike will be much more enjoyable. The best way to improve your hiking stamina is to hike more often. Start off easy and gradually challenge yourself.

When I'm unable to hike, which sadly is the usual situation, I try to perform five of the following workouts per week to stay in hiking shape. I think Isometrics and P90X2 Yoga are the most important workouts listed below.
