Free Throws

Back to the fundamentals of basketball, I will refer to the game-changing free throw. Free throw shooting is a skill that every basketball player has to work on. To improve performance and free throw percentage, it is vital to understand the maths behind it.
3 key variables can influence you shot:
1) Release height: starting position of the ball as it leaves you hand should be in line to your eyes.
2) Ball's initial vertical velocity: a rate that includes the angle and speed of the ball as it leaves your hand , and
3) Gravity: makes the basketball accelerate as it falls.
If you manage to make this three elements work together and mix them with the right shot mechanics, you will have a consistent free throw shot.
To achieve this you need to practice applying the same force to your shots every time so that release is automatic. Try to have an open, shoulder-with, stance that maximizes body balance and release in line with the eye. Power will come from your lower body muscles of your bent legs, so there is no need to jump. Also the release is a push with you elbow locking and a flick of the wrist to 'cradle' the ball and deliver it on the line dictated by the arm´s motion; it is not meant to add any power. Finally, use your fingertips to add backspin to the free throw. This will cause the ball to follow an arc toward the hoop spinning counterclockwise. When the ball hits the back of the rim or the backboard, the velocity of the ball changes as the spin of the ball is reversed. A ball with backspin is more likely to rebound into the net due to the change in velocity, angle and spin direction. The result of all this combined is a high arching shot with great predictability and repeat-ability so you free throw shots can become mechanical.
