Here is Fast Friday Fitness - feel how your own muscles work to hold ankle position, so that you can have stable ankles without artificial shoe supports or bracing, which weaken the supporting muscles from disuse:
Stand with feet parallel and look in a mirror where you can see your feet, or just look down.
Rise to toe and hold
Keep body weight over big and second toe with straight ankle position as you remain on tip-toe. Don't let your weight shift over the small toes, allowing ankle to bend outward.
Click the arrow to see this short movie of my student Diana's feet, as she first allows rolling the ankle outward when rising to toe, then at second 3 in the movie, she uses ankle, foot and leg muscles to pull to straight neutral ankle position. She prevents outward rolling as she again rises to toes three more times.
Prevent rolling outward whenever you rise on toe or push off or land from a jump or step.
Developing positioning sense in the receptors of your ankles prevents the sprain-promoting position called inversion, and gains built-in foot and ankle muscle strength and stability. Nice foot stretch too. Practice balancing on tip-toe, and rising up and down without rolling outward every day.
A few weeks ago, I attended a lecture on forensic anthropology. In general, this is the study of things you can tell from human bones in a crime setting. How old was the person? Were they male or female? How big were they? What was their probable race or ancestry?
Why was I there when my work is with the living? Two main reasons. I am the science officer for the Vidocq Society, an international forensic society. I might evaluate data, for example in an aviation disaster, whether someone might have been conscious at each point when undergoing G-forces or different temperatures and amounts of oxygen after a depressurization at various altitudes. In a scuba death, I might advise on physical changes that occur with different situations. The second reason was to learn more about bones. Bones are remarkable. Your bones know a lot about you. What was your health like? Were you active? What kind of activity did you do? When I was small, I read about an archaeological dig in ancient Rome. The bones of a girl were recovered. The account stated they could tell she carried loads too heavy for her, and was therefore (in conjunction with other evidence) probably a servant or slave. I was riveted. How could they know that? I spent years after that learning more about telling how someone moved from looking at their bones.
Throughout your entire life, when you exercise you stimulate growth of new bone cells. The physical pull of muscles thickens your bones where the muscles attach. Using your arm muscles thickens arm bones. Using your legs strengthens leg bones, and so on. This is a main mechanism of how exercise prevents osteoporosis. Without exercise, you don't stimulate enough new cells to counter the normal loss as old ones break down. Your bones thin no matter how much calcium you eat. The post Exercise is More Important Than Calcium Supplements for Bones tells more about this. Bone demineralization is rapid and serious in astronauts in microgravity (Collapsing Astronaut Gives Healthy Reminder).
How you use your muscles causes them to pull differently, giving evidence about the kind of habitual motion. More interesting is that when you are active, your bones grow and shape themselves to facilitate your motion. An example of interest to readers following the posts on squatting is that people who habitually sit for normal daily life in full squat grow "squatting facets" on their lower leg bones. These are small areas on the bone that quickly grow to make squatting more comfortable. At one point, it was a debate in anthropology that squatting facets were a marker of someone of Asian ancestry, until it was found that others who squat also grow them, and that squatting facets disappear when the person adopts a Western sitting habit of chairs and no longer squats. Babies of all races can have them.
Someone who habitually slouches can change the shape of their bones, eventually deforming them. This can occur in the spine, knees, hips, ankles, shoulders, feet, toes - everywhere you pressure your bones. Changing positioning habits to healthier ones can, in many cases, reshape the bones back to healthier shape. Think of braces on your teeth. It's human bonsai. In cases of extreme dystrophies of the muscles, someone who sits without function of their trunk muscles to hold the spine upright, can eventually deform their spine until their ribs sit on their hip bones. How are you sitting right now? The recent post What Does Stretching Do? explained a bit of why stretching isn't reducing injuries. People are stretching, then exercising and going about daily life in bent over positions that rub and grind the joints and soft tissue.
You literally shape your own health. Use the articles throughout this Fitness Fixer blog to do healthy exercise in healthful positioning so that your bones will only tell good tales about you.

April 1 seems to be a day to notice, more than usual, if things in the news are not facts but April Fool. On other days, urban legends and other stories are still popular, sometimes more popular than what is really going on.
The observation that the Earth is flat seemed obviously true at one time until we had more information. It used to be a taught as a medical fact that the cause of epilepsy was masturbation. When I was in school, one of my medical books stated that you don't need to eat calcium since you can "get all you need from your bones." It is true that you pull calcium from your bones when you don't eat enough, although with unhealthy results.
The post Forensic Science told of two crime-science myths, often still taught in forensic books and popularized in television shows, which were never true. Following are more posts hoping to replace myth with information, so that you can get stronger and do more, without the injuries or restrictions in activity that are part of many fitness or injury rehab practices.
When you take your shoes off and stand up, do your toes turn upward by themselves, as in the photo at right? That is usually from tightness in the top of the foot. You can often see the tight, string-like tendons on the top of the foot pulling the toes back. Do your toes face outward (toward the little toes) when your foot is facing straight forward (same photo). A sideways -shift is common, not only from tight shoes, but can be produced from how you walk, step after step, year after year.
Toes deform into unhealthful positions in common ways:
Shoes: Tight shoes fold and shift toes out of place. Heeled shoes push toes upward. When toes are held in one position too much, the muscles tighten and don't go back to normal length.
How You Use Foot Muscles: Many people do not use muscles in their feet or toes when they walk. They just clomp. The muscles that normally work to pull toes and forefoot downward during the weight-bearing phase never engage properly. The toes stretch upward during push-off, but not downward.
Positioning: If you walk with feet facing outward, the "push-off" phase is on the side of the big toe instead of the bottom of the foot. After years of being pushed toward the other toes, the big toe eventually tightens into the new shifted position.
Good reasons to stretch toes:
Healthy spacing avoids fungus like Athlete's foot, calluses and other injuries from rubbing, and improves needed movement.
Toes need to move through a full range up and down, and independently from each other, for balance, preventing several causes of foot pain, and for quicker, healthier movement ability. Feet are not just blocks to clomp around on.
You can avoid toes that curl, hook, hammer, face different directions, or push sideways into bunions.
Try these easy stretches:
Take your toes in your hands and bend them all downward, to stretch the top of your foot.
Take your toes in your hands and bend them all upward, enough to feel a nice stretch in the bottom of your foot, not just the toes.
Pull each toe apart from the next.
Pull the little and big toes away from each other at once, restoring healthy width to the front of the foot.
Pull any toes that are bent-up until they are back downward. Pull bent-down areas gently straight, and pull curled toes straight out to restore straight length.
Stretch deformed, squashed toes with your hands several times every day, or at least at night and in the morning, or when exercising or stretching. Reduce the need to stretch them back to health in the first place. Walk with feet (and knees) facing straight ahead. Wear shoes with room in the toes. Tight shoes are not healthy. Unhealthy shoes are not beautiful.
It is often taught that tight or snug shoes are needed for "support." However, tight shoes are not healthy for many reasons, or even needed. Tight or supportive shoes are a common source of tightness of the toes, foot, and Achilles tendon, and pain of the toes, feet, ankle, and knees. The posts Arch Support Is Not From Shoes and Which Shoes Help Exercise, Fall Prevention, and Ankles? explain more about the myth that support is from shoes.
Shoes worn snugly "for support" cause frequent problems. If your toes fit together like puzzle pieces or do not face straight ahead, as in the photo at left, it is likely that you frequently wear shoes that are too tight.
There should be space between each toe, and each toe should face straight forward, not turned toward either side (photo below right).
If you need toe separators (a soft foam device for separating toes) to paint your toenails, your toes are too tight and bunched together. Toes that are bunched together need regular stretching to separate them. Take your toes in your hands and gently pull them apart. Some of my patients use those toe separators to wear to bed. That is all right to start, but instead of only treating the result of a tightness problem, it is best to correct the problem with simple stretching before deformity progresses to the point where it is difficult to fix:
Pull your toes away from each other with your hands.
Straighten each toe gently.
Make sure all toes separate and can wiggle.
Practice wiggling your toes.
Don't wear shoes that push your toes together or keep them from moving.
Avoid tight socks and stockings - "tight" is anything that presses your toes together.
When standing, don't tighten or clench your toes against the floor or each other. Don't press toes into the ground to balance so much that they buckle and bend. Keep your weight distributed over your entire foot, including your heel. Notice if you rock forward to the ball of your foot when standing.
Take off shoes and all hosiery every day and let toes get sunlight and air.
When you exercise and walk, make sure you do not walk "toe-out." Turning the feet outward, sometimes called "duck-foot" used to be thought the normal direction of the fibers and muscles. Now it is known that both feet should be able to comfortably face straight ahead.
Toes do many wonderful things for balance, walking, ability to jump and move quickly, for the shock absorption important to your hip, and more. See the post Healthy Toe Stretches for foot stretches. The next article will give fun stretches specifically for tight toes.
Don't forget to stretch your toes. You need mobile toes for balance, healthy walking mechanics, and foot health.
Every day, take your feet in your hands and stretch your toes apart side to side, easily and comfortably. Make sure all your toes can move apart from each other, and that each one moves up and down. It is not healthy for your toes to remain stuck together and not moving. Check if you sit straight while stretching your toes and feet. It makes no sense to sit in unhealthful ways to do a health activity.
Sitting in various ways can be a built-in stretch for the toes. If you sit on your heels, as in the photo at left, or kneel on your hands and knees with toes curled under you, or when you are sitting in your chair right now, see if you can bend your foot behind you and still touch all your toes to the floor - even your little toes. Don't force toes to bend, just gently see if they all reach the floor. After stretching your toes back (toward the top of your foot) bend them all down toward the bottom of your foot. Many people, particularly people who wear heeled shoes wind up with toes that are bent upward all the time. The tendons on the top of the foot can shorten from keeping the toes bent up, and the toes can get stuck in a pulled-up position. Future posts will cover more on stretching your feet for mobility, pain control, and health.
When you sit, as in the photo above, see if you can rise to a stand without pushing off the floor with your hands or bracing your hands against your leg or knee. Use your leg muscles and get a strength and balance exercise while you get a nice stretch on the bottom of your feet.
The photo was taken when I studied a field medicine course in Cambodia. Before and after classes, you practice respect, concentration, and self-discipline. While you do this, you get a lot of physical exercise. It is commonplace for people of any age to kneel without using hands, except to hold the candles, flowers, and incense, and to rise the same way. The photo was taken in the middle of bowing, so I am not fully straightened yet. The nun is laughing. My Cambodian is so bad that I made her laugh. I think that is good exercise and good medicine too.
