* Skiing: Do 10 to 15 squats with knees aligned over feet, a shoulder’s width apart. Slowly bend your knees.
* Skating: Do several lunges. Let your back knee come down to the floor if you can, while keeping shoulders over hips.
*Sledding/tobogganing: Stretching may prevent compression injuries caused by frequent bouncing over snow. Sitting or lying down, pull your knees to your chest and hold 30 seconds.
* Shoveling snow: Not actually a sport, but many people do it for fun or necessity. Do warm-up stretching before you start, especially for your shoulders, upper and lower back, and legs. When shoveling, bend your knees to lift. Let your legs and arms do the work.
