A free kick is a great way to get a goal for your team when fouled near the penalty area. By learning to bend the ball over or around the wall with power you can beat the keeper and score a goal. This takes many hours of practice to perfect.
Set the rebounder up in free kick mode. Now place the rebounder so it is 10 yards from where you take the free kick from. Use the rebounder to protect the near post while the keeper stands nearer the far post. Now try to bend the ball over or around the wall. It is best if you work with your keeper on this drill so you can see what it takes to beat them. This is all about power and accuracy. Try this from many different spots around the penalty box and try a range of different ball-striking techniques.
