For me, fall ends with Thanksgiving and winter officially begins. I don't like winter that much so I focus on skiing. It is one of the joys of the season. If you are headed to the slopes soon, it is time to start some conditioning so you can fully enjoy your downhill time.
Squatting and cycling are great ways to get the legs ready for the slopes. Try our at your desk squats if you are anxious to get started right away. It is also a good idea to challenge the legs individually. So after working both legs together, try the one legged squat by lifting one foot off the ground and squatting on your standing leg. This works your strength and balance simultaneously, and balance is essential to skiing. Get your deep abs fired up (by pulling your navel to your spine) while you do this - they'll help you balance. Hold the position for 30 seconds to 2 minutes. Think about your ideal skiing position while you hold the position (this will also keep your mind occupied while your quads scream for mercy).
Although you might be tempted, do avoid the wall squat where you stand with your back against a wall and slowly slide down to a squatting position, using the wall as your support. This exercise puts your body in a bad position for skiing placing your weight and pelvis way behind the knees. It can also be hard on the knee joints too.
Stay tuned for more thoughts on skiing. Have fun prepping your legs for the slopes.
