Stand two to three feet away from a solid support and, with arms
and hands extended, lean against it. Bend one leg and place foot
on the floor in front of you, leaving other leg straight behind
you. Slowly move your hips forward until you feel a stretch in calf
of straight leg. Be sure to keep heel of foot of straight leg on
floor with toes pointed straight ahead. Hold for six seconds, then
relax for five seconds. Switch legs. Repeat twice for each leg.
