The following section describes the separate joints, their reciprocal connection and possible error-groups.

The body has many joints, which allow movement. The three most important joints for the movements of skiing are the ankles, knees and hips. To illustrate the importance of the function of these joints try to relate them to a shock absorber in a car. The shock absorber has an area of movement that goes from completely compressed to completely stretched. When the car is stationary, the shock absorber "holds" itself in a position that is somewhere between the two extremes mentioned above. This can be compared to the skier's basic stance. When the car begins to move and meets irregularities on the road, the shock absorber is pushed upwards so that the wheels can pass over the irregularities without being hindered. In a similar way, the shock absorber will stretch in order to keep in contact with the road the the car drives over a hole in the road. Everything put together results in amore comfortable ride and ensures that optimal contact with the road is kept. This is exactly the same thing that we strive for as skiers, to even out the irregularities in the terrain and at the same time keep a sensible amount of contact with the snow. This is primarily achieved with active legwork, where you stretch and bend your knees respectively in order to maintain contact with the snow.

The ankle joint is incredibly important - not only for the sake of balance, but also to help with edging the skis. Generally speaking, you should put more energy and focus on your feet in order to solve the many challenges that arise when skiing. That is, you should adjust your movements to keep your balance and edge the skis so that they can turn.

The further down your leg that you start a movement to adjust your balance, the better and more effective the result. For example, if you are skiing towards and unforeseen obstacle and have to adjust your balance quickly, it may seem easier to use the upper body. But as the upper body os relatively large, heavy and slow, there is a risk of over balancing - and you may end up "eating snow"! If on the other hand, you adjust your ankles and lower legs, you will be able to regain your balance much more quickly and effectively.

The knee joint is one of the most complicated joints in the human body. Due to its central position in the body, it is also the most vulnerable - especially when skiing. Unfortunately, most serious ski injuries occur in and around the knee joint. Being in good physical condition before you go skiing is essential in helping prevent serious injury.

Some knee injuries occur as a result of simple overworking the knee joints but this can usually be prevented by a good basic stance. As described earlier, there are many skiers who lean too far backwards in their ski boots. Leaning back too far exposes the knees to a particular strain as they are burdened by the entire weight of the body in addition to external forces and influences that occur whilst skiing.

Be aware of pushing your knees as far forward as possible, so that you can feel the ski boots against your shins. In this way, you achieve not only better position and balance, but significant;y reduce the risk of acid collection in your thigh muscles. A rule of thumb is that if you quickly and often succumb to acid, especially in and around your thigh muscles, your position is too static and you are leaning too far backward.

The hips are the joint most skiers use to absorb the unevenness that occur on ski runs. Big and strong muscle groups around the thighs and stomach, which are easy to "get in contact with", surround the hips. The problem is that these muscle groups are situated so far up the body that balance is not optimal if you concentrate on absorbing all the unevenness of the terrain with this muscle group. You should instead try to absorb irregularities through the feet, ankles, and lower legs. Moveable joints have the additional advantage that they help to improve your feeling for the skis and snow.

In addition to the fact that many skiers mistakenly bend over at the hips to absorb irregularities on the ski run, many skiers also curve their backs. This combination of bending at the hips and curving the back is not optimal as the basic stance, strength and ability to move is weakened.

The body is strong in its entirety, especially when each muscle group and joint works well together. However, if the backbone is bent as the body becomes locked and divided into two parts - the upper and lower body respectively - your ability to feel with your feet and ankles is reduced. Bending your back ruins good balance. Therefore you should tighten your stomach muscles and pull in your midriff under you.
