There are many factors that allow a quarterback to become effective at his position. The quarterback must be a strong leader who can communicate with his teammates. He must have good vision that allows him to see weak spots in the defense and find receivers. He must have arm strength and accuracy in his passing. In order to work on accuracy and arm strength, a quarterback can throw to passing targets that allow him to improve even when no teammates are around.
Measure a wooden "receiver" from a 7-foot by 4-foot piece of plywood. Draw the outline of a football player on the plywood and cut it out with the jigsaw. Cut another circle on the target at the hands. This circle should be about 10 to 12 inches in diameter so a football can easily fit through the hole.
Paint the cut-out figure so that it resembles a football player in uniform. It does not have to be a great piece of art, but it should look like a player because you are going to be throwing the ball at this target. Get help from a friend or a family member if you are not a good artist.
Attach the cut-out receiver to the wooden base with wheels. You can do this by hammering nails into a wooden base and a supportive 2-by-4 beam to make sure the receiver stands up. Once the wooden base is secured, you can move the "receiver" anywhere you want on the field.
Take your receiver to the field and set it up at various distances to improve your accuracy. You will need six to 10 footballs at your disposal to test your throwing accuracy. Throw the footballs in rapid succession so you can build muscle memory and accuracy.
Keep the receiving figure in a dry place when you finish working out with it. You do not want to leave it out in the rain or other elements if you want it to last for a full season or longer. Keep it in a garage or shed so you can practice with it whenever you need to.
