Step Ups September 15, 2014ExercisesSSD What: Strength and endurance building movement that mimics hiking. How: Alternate feet each step, and stand all the way up at the top of the bench/box, each rep. Don’t “skip” your feet on the top of the box, cut your hips or knees short, or lean far forward. Why: To hit legs and lungs and to build strength for hiking. Simply step up onto 16-18″ high box or bench , alternating feet each step. Add a loaded pack (15-40 pounds) for more resistance. Go for the total number of prescribe reps. For example, if the session says: 1) 500x Step-ups in 25# pack Then do 500 Step-ups continuously (250x each leg), without rest, with a backpack loaded with 25 lb.
