hello
just so you know moving your feet back on the approach will increase your foot speed(makes you take longer strides, can throw your timing off if your having timing problems).. thats a no,no.. during a practice session try this.. without your ball walk off a couple normal shots to see how close you are to line(maybe even going over the line is ok)..watch your footwork to see how long your steps are.. if you are 6inches over the line, move up 12inches to start.. take your normal footwork and cut your steps(the distance of your normalstep)in half if not more(making you first and second steps much shorter)..you want to walk heel to toe trying not to lift your feet off the ground(almost sliding them to start).. this will actual slow your feet down a ton.. it will take alittle time to get comfortable,especially if you been dealing with this problem for a while.. once you have become comfortable with it you will notice that your timing has also gotten alot better.. when you perfect it you will be able to move your feet forward and backward to adjust your speed on shots and etcc,etccc(but thats another show))..lol.. hope this helps.. if you need anymore help with this or have a question plzzz ask.. slashrr69
