Here’s one of our favorite all-season exercises: the minimalist Drop Jumps. All you need is two (sturdy) benches or chairs that are slightly taller than your knees. (Yes, a fitness box is best, but still…) Here, Ernie Reimer, USSA’s Strength and Conditioning Coach, and U.S. Ski Team alpine athlete Hailey Duke take you through a step-by-step introduction to Drop Jumps. This simple and easy exercise develops power and explosiveness in your legs, which is key to expert all-mountain skiing.
