Strengthen your basketball skills by incorporating plank side knee ins into your training routine. This exercise focuses on coordination and control of the legs and hips, both of which are integral in basketball movement such as a vertical leap. Start by getting into the plank position and then bring up one knee while rotating the hips at the same time. Switch legs with each repeat to ensure an even workout and target different muscle groups. With regular practice, you will be able to draw on strength in basketball movements more easily.
