It comes, unsurprisingly, from Southern California, but it can be done anywhere there is a towel, if not a beach. The Los Angeles Times explains that New York-based fitness consultant and personal trainer Sara Haley
devised these four exercises because she and her clients travel often, and gym equipment is often nonexistent. Ready? Here we go:
1. Run back and forth over the towel while on the balls of your feet. This works the calves and quadriceps, and maintaining balance while
running works the core muscles. For the first half, start with the left foot, going left-right across
the towel and left-right back down. Halfway through the exercise, switch
and start with the right foot.
2. Stand on one leg and bring the other leg up and bend
it so the foot is resting above or below the knee, but not directly on
the knee. The bent leg is extended out to the side. Hold the towel above
the head in both hands and think about pulling the towel apart,
engaging the back muscles and retracting the shoulders.
3. Place the towel vertically to the right of you. Standing with feet together, bend the knees and tuck the arms back. Hop over the towel, allowing the arms to swing up; and land
toe-heel, with soft knees.
3. Stand with feet shoulder-width apart and bend the
knees slightly. Bend forward at the waist, making sure the head is
aligned with the spine. Hold the towel with both hands behind your back,
arms straight but not locked at the elbows, palms facing away from the
body. Raise the arms a few inches and do several little pulses, keeping the
shoulders square and focusing on the triceps muscles in the back of the
arm. Complete the range of motion by bringing the arms back down to the
starting position.
Please read #3 (the first one) and, in more detail, describe what one is supposed to do. And, I suggest that the author heed the most recent post about wine staving off cognitive decline before further attempts at sequential numbering.
