You might train your upper body endlessly for the demands of technical climbing, but getting to intense backcountry objectives demands a base strength in your lower body as well. Legs are the main propulsion you have in the mountains, and their large muscle mass requires special attention. We’ve developed a solid, structured training program that will help you build the necessary strength and endurance to achieve your goals, keeping you healthy and energized when you set off from high camp.
This base training period includes two specific exercises that will improve your fatigue resistance, so you can handle more intense climbs—even after you’ve hiked several hours with a weighty pack. Do hill sprints first because they allow you to build maximum leg strength and power before getting into weighted hill climbs, which simulate the endurance needed for ascending moderate to steep alpine terrain.

Find a steep (20 to 50 percent incline, steeper is better) hill with decent footing so you can sprint and are not dodging roots and rocks; stadium stairs are also a great option. A steep incline increases the workload on legs and hips without the impact or increased training time it would take to achieve the same benefit through running on flat terrain. Although hill sprints would normally fall under the category of power training, which emphasizes speed and explosiveness, they also offer dramatic benefits in pure leg strength. This exercise is simple, effective, specific, and best of all, highly portable—especially if you don’t have a gym.

Engage a few friends to push a car back and forth in a parking lot. Put it in neutral, and make sure you have quick access to the brake. As you push one way, your friend pushes the other, so it’s not really moving that much. Push on the front and rear bumpers so that you can really lean into it and get your big leg muscles involved. Take a few minutes of rest between short pushes of six to 10 seconds and you’ll see amazing results in leg strength.
The goal of this phase is to increase how long your muscles can operate at a high percentage of max strength, which improves your endurance. Do this after completing 12 weeks of hill sprints, and plan on finishing at least two weeks before your objective. This stuff is going to make your legs very tired, and you will not be at your best until you have a good recovery period. If your performance improves for the first couple of weeks, but then plateaus and drops off, you are doing too much and should drop down to one session per week. Jugs of water are good to carry because you can pour them out at the top of the hill without trashing your knees with the extra weight on the way down. If you’re lacking a handy stream, you can carry rocks and dump them out at the top. Just bring extra padding for your back.

So, you’re in North Dakota and the highest thing within 150 miles is a hay barn. It can be very effective to do this type of weighted workout using only a 12-inch box to step up and down. The boredom factor may become extreme, so you may want to arrange a source of entertainment, but it’s easy to control the intensity and overall quantity of the training.
