Begin lying on your back with your right arm reaching overhead and your left leg flat on the table. Your right knee should be bent 90 degrees and your hip 45 degrees. Place your left wrist beneath your back to prevent your back from flattening against the ground. Slowly begin by raising your left knee and right arm at the same time until your hand touches your knee. Be sure not to lift your head or allow your spine to flatten against the floor. Return to the start position and repeat for three sets of 10 repetitions on each side, twice per day or as directed.
