The proper for an air squat Is:
1. Begin by standing with your feet shoulder-width apart, toes slightly turned outwards.
2. Engage your core by drawing your belly button in towards your spine.
3. Lower your body by bending at your knees and pushing your hips back as if you are sitting into a chair.
4. Keep your chest lifted and your back straight throughout the movement.
5. Go down until your thighs are parallel to the ground, or as low as you can comfortably go while maintaining proper form.
6. Push through your heels to straighten your legs and return to the starting position.
7. Repeat for the desired number of repetitions.
