Stand straight and step forward with your right leg. Assume a lunge stance position with right foot forward with the knee bent and front thigh parallel to the ground.
Extending through both legs, jump as high as possible. As you jump as high as you can, switch the position of your legs, moving your right leg to the back and the left leg to the front.
As you land, absorb the impact through the legs by adopting the lunge position. Repeat the exercise according to the training plan alternating legs.
