Performing the: A Step-by-Step Tutorial Warming-up in Lunge

Lower your body until your right thigh is parallel to the floor and your right knee is stacked over your ankle, this is the lunge position. Your back knee should hover just off the ground.
Push off with your right foot and return to the starting position.
