Today we are going to take about concentration. According to records, badminton is the fastest sport in the world. Malaysia palyer Lee Chong Wei, managed to smash a 417km/h shot during a professional competition. Even though this kind of speed may not happen to us as an unprofessional player, however, as what you can see, the shuttle travelling speed during this push shot rally is still quick fast, if you do not pay attention to the shuttle, you will lost this match. Concentration also reflects on energy control. For example, hand control and mind thinking during net shot, loss concentration will cause the shuttle travel either too higher, too far or does not cross the net. Concentration reflected through your body movement as well. Once you are fully concentrated your body will move toward the direction that the shuttle travel.
