Start on your hands and knees in a tabletop position. Make sure your knees are under your hips and your wrists are under your shoulders.
Slowly arch your back, tucking your belly button in toward your spine and letting your head drop down for the 'cat' position.
Then slowly let your belly drop down toward the floor, lifting your chest and head up towards the ceiling for the 'camel' position.
Repeat this process, moving at your own pace, for about 5-10 repetitions.
Remember to breathe deeply throughout the exercise, inhaling during the cat pose and exhaling during the camel pose.
Please consult with a fitness professional or physical therapist to ensure these exercises are suitable for your physical condition.
