Split stance knee ups are an excellent basketball drill to improve your dribbling agility. To start, stand in the split squat position, positioning your feet hip width apart with one foot in front and one foot behind. Make sure you maintain a stable base from your neck down while keeping your arms loose and ready to move. After establishing this foundation, go up off the floor, bringing your knee up and balancing yourself as you pause for a second at the lowest point. Doing split stance knee ups will help basketball players increase their agility, coordination, ankle flexibility and general balance while they practice their basketball drills.
