well, it is important to have excellent balance for obvious reasons. building strong abdominal muscles can help with your balance. also work on leg stretches to do the more advanced stunts. try doing the butterfly, figure 4's, touching your toes, and even doing the stunt on the ground. this works with stunts such as the arabesque, scale, and chin chin.
^^^^ lets try and make this simple. you can do your splutz no both sides for at least 25 seconds and more, wall sits to improve your leg muscles, you can do wall splitz, and so many more to name. Then once you have done all that you should be ready for doing some extreme stunting.
