As a kid ski racer, I used to despise dryland training in the fall. All those box jumps and wall sits and push ups. But now, lunges at the gym mean that winter is coming and that’s all good news in my book. I went to Park City, Utah, recently to follow around X Games gold medalist Jen Hudak during her regular workout at the U.S. Ski Team’s training facility. Here’s the video I put together for ESPN. If you’re looking for a good, butt-kicking pre-season workout, I highly recommend taking some notes.
