Ernie Reimer, Strength and Conditioning Coach for the U.S. Ski Team, and alpine athlete Julia Ford take you through a step-by-step introduction to the Ski Team’s Box Clean-Pulls. The exercise builds core power, which is key to strong acceleration out of turns. The video, part of SKI’s fitness series with the U.S. Ski team, was shot at the USSA Center of Excellence, Park City, Utah.
