Line up your feet on the line
Make sure your toes are touching the free throw line
Make sure you aim the ball on the square
Make sure you bend your legs to get more power on your shot
Make sure you line up your shot again because you'll loose focus when your bending your legs
Make sure your hands are positioned good so you throw the ball strong
Focus your shot twice to be sure your position of your aim is good
If you follow all these steps then you will have a free throw and will likely score alot
