WHY: This exercise is great for strengthening the hip and thigh muscles particularly the quadriceps and gluteals. Strengthening these muscles will help with ambulating up and down stairs.
HOW: Begin standing in a split stance with one leg in front of the other. Put a majority of your weight on your front leg and perform a reverse lunge with your back leg. In this position drop down with a majority of your weight in the front leg (70-80%) as your reach up towards the ceiling with both of your arms. Lunge yourself upright and perform on the opposite side.
FEEL: You should feel this exercise in the front of your thigh and butt muscles.
