Press-up extension
Once again, lie face down with your hands flat next to your shoulders. Press your palms into the bed while lifting your upper body, making sure to keep your hips and pelvis on the bed. Stretch your spine from your tailbone to your neck while slightly arching your back. If you feel pressure on your lower back, stop lifting your chest. Hold this position for 10 seconds and then slowly lower yourself back to the start position. Repeat this exercise 10 times, making a set. Do 3 sets of this exercise in total.
