DON'T: Strain your lower back to reach pots and pans on the stove or shift your weight to one hip while you stir or mix ingredients.
DO: Use food prep time to improve your posture. Try pliés: Stand tall with toes facing out at a 45-degree angle. Tuck your tailbone under and bend your knees until they are over your toes. (Hold on to the counter or the back of a chair if you have trouble balancing.) Keep your chest upright and your hips and shoulders in a straight line. Return to standing. Repeat 12 to 15 times.
THE PAYOFF: Eases pressure on your lower back and straightens your spine.
