Diversify Training Regimen
If your are not a professional dancer, and do ballet just as an exercise, it is better you diversify your exercise regimen to include more exercises. Relying just on ballet for fitness is not good for health of your knee joints and doctors often recommend different exercises for fitness, not just ballet alone. This can help your knees endure the workout pressure longer.
If you are a professional dancer and often have to perform with your group, you should be doing knee exercises even then. Doing knee exercises other than ballet can help strengthen muscles of your knees and they can sustain pressure of your ballet workout. Without exercising, it is very hard for knee joints to bear the continuous pressure of twisting, bending and jumping.
You can also protect your knees by doing warm-up exercises before ballet dance. This will help your knees to ease into the ballet work, which is hard and faster. Just jumping on the stage to dance rigorously does not help your knees, so they are always exposed to serious injuries.
A proper rest is must for your body to endure longer even if you have a busy schedule. By consistent workout, your knees become tired, and their resistance level to pressure of the work is reduced. If you work hard and consistently, you are risking your body to suffer more injuries as it cannot take extra workload.
Right Rhythm and Balance
You can avoid knee injuries by maintaining a right rhythm of your feet and balance of your body. Each step is carefully taken in ballet dance, and losing your rhythm and balance can hurt your knee. It can put pressure on a certain part of the joint while twisting or bending and you end up hurting your knee seriously.
