The best way to prepare for any surface is to do tennis training on it as much as possible. This is the law of adaptation and it especially applies to clay-court tennis. On this surface, you need to learn how to slide into shots, recover after hitting, and stay balanced. When you are born in a country where the main surface you train and compete on is clay, it just becomes natural to move efficiently, you don’t even realize it happens. You are able to start sliding when you build up that confidence. The other requirements are good balance, a low center of gravity, and most importantly, strength in your legs. For better balance and control, it’s critical to have a good low stance, keeping yourself balanced and being aware of the first step movement.
