Exercise Advice: Stand with your feet about shoulder width
apart and grab a dumbbell in each hand and let them hang at your
sides. Begin by reaching one of your feet back behind you like you
are taking the first step if walking backwards. Really reach back
with this stride to get a good stretch. Bring that leg back to the
start position and repeat the same movement with your opposite leg.
Be sure to keep your back firmly upright and straight throughout
this exercise.
