A great warm up and stretching exercise for core.
Sådan gør du
Get onto your hands and knees, with your knees hip-width apart. Make sure your hands are under your shoulders and your knees are underneath your hips. Take a deep breath in and arch the back, pulling your belly button into your spine. Hold at the top of the movement for 2-3 breaths. You should feel a stretch in your spine and lower back. This is the cat part. Then move into the cow part by lowering your belly to the floor, rounding your spine and raising your head and neck to the ceiling. Repeat for at least three-five breaths.
