What it stretches:
Obliques, lats, shoulders, hips
This full side stretch will have you breathing easier, sitting up straighter, and keep your core more toned.
Standing with feet wider than hips, extend one arm overhead and support yourself with your other hand on your hip (or leg or on a chair) as you lean as far as you are comfortable to the side. Hold, breathing deeply, then slowly return to an upright position and repeat on the other side. At no time should you be leaning forward or backward, only directly sideways, as though you're squashed between two panes of glass.
