Lie back on a mat with knees bent, arms at sides, and head and shoulders raised a few inches off the floor. Raise both arms in front of your body, and alternately reach as high above your chest as you can, grasping the air with each hand as if you were climbing an imaginary rope. Perform two sets of 10 to 12 repetitions with each reach counting as one repetition.
