Why you need the lunge… 

The lunge forms the basis of many athletic movements: think of stopping on a dime like a soccer player, doing a crossover dribble like a basketball player, and any type of bounding movement. It is also a great way to train overall balance, strength, and joint alignment in the lower body, without weights. Here is how you execute the lunge. Notice the abdominal bracing (belly button pulled in tight), slight forward torso angle, and joint alignment of knees and ankles. Ensure the anterior hip of the back leg is stretched, and front glute is “loaded”. I am performing Grey Cook’s In Line Lunge in the right picture:
