How To do Lunge
1. Stand with your upper body straight and with your feet hip-width apart.
2. Place a foot forward and bend your knees until they reach a 90-degree angle by lowering your bottom. During the movement, maintain your upper body and back straight.
3. With the weight placed on your front foot heel, push to return to the starting position.
"Keep your body upright through the movement. Try to avoid leaning forward too much."
