THEY may never pull a locomotive with their toes, but a few intrepid fitness pioneers are diligently exercising their feet with the dedication of true believers.
And they may be on to something. Many podiatrists believe that putting feet through a simple exercise regimen designed to build up foot strength and flexibility can save some folks a world of hurt.
"A lot of injuries we see can be prevented if you have stronger feet," says Dr. Noreen Oswell, chief of podiatric surgery at Cedars-Sinai Medical Center in Los Angeles. And though podiatrists have many recommendations for preventing injuries (such as wearing proper shoes), only one thing, they say, will directly strengthen the feet -- and that's exercise.
Regularly exercising your southernmost appendages can strengthen muscles of the foot and ankle, warding off tendonitis, plantar fasciitis and good old-fashioned foot pain, says Dr. Douglas Richie, a podiatrist in Seal Beach and past president of the American Academy of Podiatric Sports Medicine.
A toned, strengthened foot, furthermore, can reduce the occurrence of "sore, aching feet," which are often the result of muscle fatigue.
Regular exercise can also improve flexibility, thus boosting mobility.
Most people who seek out foot exercises -- generally athletes and folks who are on their feet a lot -- do so with physical therapists or trainers. But an elite few go a different route: foot fitness classes, in which students assemble for regular muscle-strengthening workouts.
Finding these classes takes a little legwork. "It's not like you can open up a catalog to a college and say, 'Oh, foot aerobics!' " says Carolyn Sery, a sales rep and dedicated foot exerciser.
Sery has been taking foot fitness classes off and on for almost three years, ever since painful bunions made standing on the job increasingly difficult. She was introduced to the concept by exercise instructor Shuriu Lo, who was training her in Pilates at the time.
On a recent Friday morning, we paid a visit to Lo's new studio at 2020 Fitness in Long Beach, to learn what goes on at a foot fitness class.
Lo and three students sat in a circle on stools at the homey mom-and-pop Pilates and Gyrotonics studio and commenced their weekly 30-minute foot exercise routine without any ceremony or small talk.
They knew the exercises by heart, and moved into and out of them with the precision of a well-trained drill team.
They scrunched their toes like little inchworms, scooting the foot forward and back.
They raised their toes, then lowered them one at a time, starting with the littlest.
They interlaced their fingers in their toes, rotated each foot and walked over small rubber domes known as wakers.
Then, toward the end, the students repeated some of the exercises while standing on a "hypergravity platform" -- a vibrating exercise device that provided a little shake-n-bake foot buzz.
Thirty minutes a week may not sound like much, but Sery credits it with helping her stay longer on her feet -- and with less pain -- during her job servicing accounts at greeting card stores. She also believes it has helped her avoid surgery.
"Standing for long periods is tiring and painful unless I do my foot class exercises," she says.
To supplement the benefits of the class, she has her own personal pair of toe stretchers that she wears when she can: soft, pliable devices worn on the feet that fan the toes outward, forcing a little extra space between them.
Although there isn't empirical evidence proving their efficacy, some physical therapists and their clients believe the stretchers improve flexibility and reduce pain.
Foot fitness isn't exactly a booming business, but a number of physical therapists and trainers do incorporate the principles into their practice.
For example, Marie-Jose Blom-Lawrence, director of Long Beach Dance Conditioning and Angel City Body Kinetics, and an instructor of anatomy and physiology at Loyola Marymount University's department of dance, is a big proponent of foot exercises -- instructing trainers in foot fitness and lecturing on the topic at workshops.
She believes that certain orthopedic problems, such as back pain, can often be traced to the feet. "The feet are carrying and organizing your body," she says.
She thinks it's a shame that when most of us formulate a fitness plan, feet are the last thing we consider.
"When we think of the feet, it's related to fashion and not health," she says.
"People work out, and go and have pedicures, and it's all for the outside. They're not paying attention to the structure of the foot."
Kim Finklestein, a physical therapist at Postureworks in Santa Monica, also includes foot therapy and foot fitness instruction as part of her practice. She even has a "toe mobilization" program, designed to restore flexibility of the toes.
