How to do squats and lunges
Stand erect with your feet approximately one shoulder width apart.
From there, you can widen or narrow your stance depending on which muscles you are targeting-a wider stance works the hamstrings and glutes, while a narrower stance works the quads. Point your toes slightly outwards, as this helps to stabilize your stance.
Keep your arms extended in front of you. Push your hips back, slowly bending your knees to a 90 degree angle.
