Waddling around with 30 extra pounds on your middle can be a real pain in the … back. To alleviate some discomfort, try an exercise we affectionately call "The Beached Whale." Lie on your back, bend your knees and lift your butt about two inches off the ground. Release and repeat. Assuming "the delivery position" might make you feel a little silly, but it also might make your back feel a lot better.
