Learning to be explosive laterally is an important part of guarding the basketball on defense. When the offensive player makes a dribble move in either direction, the defender must be able to slide laterally at a slight backwards angle to cut them off with their chest. If the player is not able to contain the dribble than the offense is going to have free reign to the paint, and it will be a long night.
The resistance band zig zag defensive basketball drill is going to work specifically on moving laterally, and doing it with resistance. By using the resistance band to train, you are going to force your muscles to work harder than they normally would. The zig zag drill is a common defensive basketball drill, but the resistance band takes it to a new level. This basketball workout doesn't need to be done everyday, but it is good to work on it once or twice a week.
