When I was having some back issue 2 seasons ago I went to see someone who worked for a place called Egoscue. Pete Egsoscue started developing exercises that help the body re-position its alignment. He started working with back patients who had gone through one or several surgeries and were still in back pain. Pete and his team have had great success working wth thousands of people over the years.
Enough with the commercial for Egoscue.com. Here's where it relates to skiing. One of the things they wanted to do with me was to increase my ankle felxibility to allow better weight transfer on each step (I didn't not always completely transfer weight to my right side, which is the ankle I broke twice). I did this particular drill every day for several months. It helped a lot, but when ski season started, I noticed a huge difference, and I was immediately able to get much large edge angles from doing this drill. I now do this 4-6 times per week leading up to sik season and 3-5 times per week during it. IMO, this will immediately benefit everyone's skiing. So here it is:
They are called Supine Foot Circles & Point/Flexes
To get a solid result you need to do 40 reps in each direction of the foot circles and 40 reps of the point/flexes (3 sets of 40 on each side). Past about 25 reps it will start to hurt and you will notice how tight and immobile your ankles are (or at least mine were). It does get easier after about 4-6 days.
Lie on your back with one leg extended and the other leg bent and pulled up toward your chest
Clasp your hands behind the bent knee
Keep the foot on the floor pointed straight up toward the ceiling and your thigh muscles tight
Circle the lifted foot one way for the indicated number or repetitions, then reverse direction for the same number of reps
Make sure the knee stays absolutely still with movement coming from the ankle and not the knee
For the point/flexes, bring the toes back toward the shin to flex, then reverse the direction to point the foot forward for the indicated number of reps
Switch legs and repeat
This exercise promotes proper function of the lower leg muscles and encourages stabilization of the hip joint on the same leg. As I said before it immediately helps with everyone's skiing even though that is not what it was designed for.
I feel confident that anyone who does these will get a similar resullt iin their skiing. Enjoy!!
