Grand Canyon Hike

Both the downhill and the uphill of backpacking the Grand Canyon is challenging. Built by a doctor and expert backpacker, this program has 4 components. First, eccentric loading strengthens the muscles for downhill. 5-second slow descent on your squats and step-downs is what "bulletproofs" your knees. This eccentric loading creates the braking strength needed to hike to the bottom without "noodle legs" and debilitating pain the next day. Second, build the glutes and quads unilaterally to mimic the uneven steps back up on the Bright Angel or South Kaibab trails. Third, some upper body for carrying your backpack and using poles. Fourth, a treadmill block as a high-intensity incline finisher to build sport-specific muscle endurance. 

I built a 13 week progression. Month 1 is Foundation. Perform exercises with bodyweight or light dumbbells. Focus on Time Under Tension (slow, controlled movements). Month 2 is Hypertrophy: Increase weight so that the last 2 reps of every set are difficult to finish with good form. Month 3 is Peak Load: Perform all strength exercises with max dumbells and treadmill with weighted vest/backpack. On days you do not bring your weighted vest, you can compensate by using the Maximum Incline (15%). At 15%, even a slow pace of 2.5 mph creates significant mechanical tension on the calves and glutes, simulating the "Big Step" required to climb out of the Canyon.

I recommend a two week "Taper" period prior to the trip. Taper is to allow your body to fully repair muscle micro-tears and replenish energy stores so you arrive at the trailhead with 100% capacity. Generally, you achieve this by reducing your total training volume and weight by at least 50% while maintaining light movement to keep your muscles "greased" and mobile. I did not include the taper in this program.
