16. Zombie Squats
Stand upright with your chest slightly lifted, your feet hip-width apart, arms straight out.
Then push your hips back and bend your knees, keeping your torso straight.
If you are flexible enough, you can sink down until your buttocks meet
until your buttocks touch your calves. But make sure that you do not bend your spine.
If necessary, adjust the position of your feet and torso before completing the next repetition.
