Next to the squad lunges are the best exercise to get stronger and more muscular legs. They target pretty much all the leg muscles including your quads, glutes, hamstrings and calves. Stand with your feet shoulder width apart in your hands on your hips while inhaling, step with one leg forward and flex the knees to drop your hips. Keep your back straight in your front knee above the front foot. While exhaling, extend the knees and drive through the heel of your left foot to raise yourself back up. Step forward and repeat the exercise on the opposite leg.
Along lunch works your glutes while short lunch targets the quads. Make sure that you leave knee points in the same direction as your lead foot throughout the exercise. For less intensity, try split squats. You also do the lunge movement but your body remains in the same place.
