hey guys I am new to kickboxing and I am finding difficulty with my stance, balance and footwork when giving a jap, right hand, hook or an uppercut. I know how they should be done but I still do them wrong. so are there are any exercises or methods that can improve my footwork and stance. for example when I was in wing chun to teach me the footwork my teacher gave me a soccer ball and told me to put it between my knees and hold it while moving as an exercise for footwork. also there were lines on the floor to show me where to place my feet and indicate to me if my feet are too wide, too far, too close and other mistakes in foot work, is there is any websites or exercises you know similar to that for kickboxing footwork.
