The Origins of the Presidential Fitness Test

The Origins of the Presidential Fitness Test

Were you more traumatized by the sit and reach or the pull-up?
It was born out of Cold War fears of an overweight, sluggish populace. It tormented students, who viewed it with dread. And although educators were unclear at best about its benefits, it endured for generations.

It was the Presidential (or President’s) Physical Fitness Test. For decades, students took it (or were subjected to it, depending on your outlook), demonstrating physical fitness through running, sit-ups, and pull-ups, among other tests.

And then it was gone.

The Cold War Origins of the Presidential Fitness Test

The Presidential Physical Fitness Test, like many things in modern American life, grew out of national defense fears.

The U.S. military ramped up its study of nutrition around the time of World War II, in no small part because of the decade that preceded it. The Great Depression led to widespread hunger; immediately before the war, it was estimated that a third of draft rejections were related to poor nutrition.

But by the 1950s, a different problem was starting to develop. The Cold War was in full swing, and with the launch of Sputnik in 1957, the United States was losing the Space Race. There were concerns over a “missile gap”—and there were concerns about a fitness gap, too, thanks to the fact that Americans had a standard of living unequaled in the world.

In 1955, Jack Kelly, an Olympic rower-turned-millionaire in the building trades (and father of actress Grace Kelly, the future princess of Monaco) brought a troubling study to the attention of Pennsylvania Senator James Duff, who shared it with President Dwight Eisenhower. Soon, the president, the senator, Kelly, and more than two dozen other sports figures gathered at a White House luncheon to hear about the study directly from its co-authors: Hans Kraus, a medical doctor and an associate professor at New York University, and Bonnie Prudden, a director and owner of the Institute for Physical Fitness in White Plains, New York.

The scientists revealed that nearly 58 percent of American youth failed at least one of the six mobility tests administered, which included whether they could do sit-ups and touch their toes—and if that wasn’t concerning enough, only 8.7 percent of European children failed at least one test.

In its August 1955 issue, a new magazine named Sports Illustrated called it “The Report That Shocked the President” and quoted Kraus, who said, “We’re paying the price of progress … The older generation was tougher because it had to undergo adequate physical activity in the normal routine of living. We have no wish to change the standard of living by trying to do away with the automobile and television. But we must make sure that we make up for this loss of physical activity. In other words, let’s take the sting out of the benefits.”

Eisenhower took action in 1956, signing an executive order to start the President’s Council on Youth Fitness with Vice President Richard Nixon as chairman. The following year, a conference was held at the U.S. Military Academy (Eisenhower’s alma mater) to develop a plan, and in 1958, the first youth fitness test standards were unveiled: A shuttle run (a run back and forth between two markers to test speed and agility), a 50-yard dash, a 600-yard run/walk, pull-ups, standing long jump, sit-ups, and a softball throw (which, it was supposedly noted, demonstrated the same skill set as throwing a hand grenade).

Enter JFK

Eisenhower’s time in the White House was up in 1961; his vice president, Nixon, was defeated in the 1960 presidential election by Massachusetts Senator John F. Kennedy. Kennedy was a marked change from his predecessor: Eisenhower was old enough to be his father (Nixon’s too), and, after establishing the council, had very little to actually do with it. The new president’s own vigorous activity (which belied serious health issues, including back pain, colon problems, and Addison’s disease) led him to encourage others to remain active and healthy.

Kennedy—who thought fitness wasn’t just a youth issue—wrote in the December 26, 1960 issue of Sports Illustrated that “human activity, the labor of the human body, is rapidly being engineered out of working life.” Echoing some of the same points raised by his predecessor Theodore Roosevelt in the 1899 speech “The Strenuous Life” (which he even quoted directly), Kennedy noted that “in a very real and immediate sense, our growing softness, our increasing lack of physical fitness, is a menace to our security … such softness on the part of individual citizens can help to strip and destroy the vitality of a nation.” In 1962, Kennedy found one of Roosevelt’s executive orders urging U.S. Marine officers to tackle a 50-mile walk in 20 hours over the course of three days, which his council spun into a national fitness campaign, complete with publicity blitz (Kennedy’s brother, Attorney General Robert F. Kennedy, did the hike in his Oxfords). Kennedy also changed the council’s name to the President’s Council on Physical Fitness.

Kennedy’s council developed a curriculum to improve physical fitness and encouraged participation. Lyndon Johnson—who became president after Kennedy’s assassination in 1963 and was elected to a full term in 1964—undertook another presidential fitness survey in 1965. The results were markedly better than the previous decade. In 1965, he implemented the Presidential Physical Fitness Award, which was given to students who scored in the 85th percentile or higher in a series of physical fitness tests similar to the 1958 test (by that point, a flexed arm hang had replaced modified girls’ pull-ups, apparently because it produced more reliable scores). He also changed the name of the council once again, this time to the President’s Council on Physical Fitness and Sports. The President’s Physical Fitness Test had taken its full—but not final—form.

Generational Trauma

Almost as soon as it was introduced—and for generations after—the Presidential Fitness Test was absolutely traumatizing. “The worst part of the Fitness Test for an out-of-shape kid wasn’t the actual exercise,” Rodger Sherman wrote on SBNation. “It was the fact that everybody in your class saw you trying to exercise and saw how bad you were at it … so many of us were humiliated.”

Even gym teachers realized that the test’s effectiveness was counterbalanced by embarrassing students enough that they dreaded it. “We knew who was going to be last, and we were embarrassing them,” phys ed teacher Joanna Faerber recalled to NPR in 2014. “We were pointing out their weakness.”

The test was modified again in 1976: the softball throw was dropped (it was theorized that the throw was a test of skill, not of fitness), the sit-ups were changed from straight legged to a timed, flexed-leg sit-up; and longer runs were added as options. Another survey was performed a decade later, with additional changes to the test (including the addition of the dreaded sit-and-reach), but none has been done since. In fact, if there’s anything the President’s Council on Physical Fitness and Sports became known for after that, it’s for the litany of celebrity chairpersons, including Arnold Schwarzenegger, Florence Griffith Joyner, and Lynn Swann.

In 2012, the President’s Physical Fitness Test was replaced with the Presidential Youth Fitness Program as part of the Let’s Move! initiative, which aimed for a more holistic approach to keep children physically active and teach lessons to ensure good choices in health, activity, and nutrition. The Youth Fitness Program does include an assessment, but the skills tested—and the parameters—are vastly different.

“The thinking is totally changed,” Faerber told NPR. “Now you want to get into the healthy fit zone, instead of being the person who can throw the softball the farthest.”

The Evolution of the Presidential Fitness Test Through the Years

What began as the Youth Fitness Test has evolved both in skills and in name since it was created in 1958. Originally, the test was based on the work of the American Association for Health, Physical Education, and Recreation (AAHPER; later, they’d change Association to Alliance, and later still add Dance and become AAHPERD). In the mid-1980s, The President’s Council on Physical Fitness and Sports (later the President’s Council on Physical Fitness, Sports, and Nutrition, abbreviated PCPFS and PCPFSN) took the lead; they changed the test markedly and would continue to tweak it until 2012. While other school fitness programs emerged in this era, here’s how the skills included in the more government-sponsored tests have changed over the years.

The Best Way to Take a Nap, According to Experts

The Best Way to Take a Nap, According to Experts

Claremont Colonic Center
Timing matters when it comes to taking the perfect nap, but it’s not the only important factor to consider.
Napping is a divisive topic, not unlike cilantro or pineapple on pizza. Some swear by the rejuvenating power of a midday snooze, while others claim they can’t do it or wake up feeling worse than before they closed their eyes.

Though naps can get a bad rap for making people feel groggy—or even making it hard to fall asleep at night—these gripes often stem from people simply doing it the wrong way.

The good news is that with a few simple tweaks, anyone can elevate their catnap game and even improve their overall sleep hygiene. With these expert tips, you’ll be well on your way to becoming a napping pro.

Why Timing Matters for Naps

The key to timing naps correctly is to align them with the natural dip in your circadian rhythm, the internal clock that regulates your sleep-wake cycle. This means that the best time to nap is directly connected to waking time, according to Dr. Sara Mednick, a cognitive neuroscientist at the University of California, Irvine, and the author of Take a Nap! Change Your Life.

Other experts—such as Dan Pink, author of When: The Scientific Secrets of Perfect Timing—cite research that divides us into three chronotypes, indicating when our energy levels are at their peak. There are larks (morning people), owls (night people), and third birds (everyone else). Researchers have developed assessments to discern one’s chronotype, and Mednick created the Napwheel to help would-be nappers gain a better sense of the right time for a snooze.

For those who wake in the morning—say, between 6 a.m. and 7 a.m.—the best time to lie down will likely be somewhere between 1 p.m. and 3 p.m. (Think of that post-lunch slump: that’s your body’s cue for a nap.) A little shuteye at this time won’t interfere with your nighttime sleep, as it works with your body’s natural rhythms. However, napping too late in the day, especially close to your bedtime, can make it harder to fall asleep later.

The Power Nap vs. The Sleep Cycle Nap: What’s the Difference?

According to Mednick, nap duration is also crucial. The classic “power nap” is typically a short 10- to 30-minute doze. This duration allows you to reap the benefits of increased alertness and focus without entering deep sleep stages. (Waking from deep sleep often leads to sleep inertia, that groggy, disoriented feeling that can last for several minutes or even an hour.)

If you have more time and want to improve your memory, aim for a 90-minute nap. This allows you to complete a full sleep cycle, minimizing the risk of sleep inertia. But be careful, as a haphazard snooze can disrupt your circadian rhythm.

What Are Coffee Naps—and Why Do They Matter?

Perhaps counterintuitively, coffee and naps can be a powerful combination. The coffee nap—or “nappuccino,” as Pink calls it—works by taking advantage of the time it takes for caffeine to kick in.

To try it for yourself, drink a cup of coffee right before your nap, then set an alarm for 20 to 25 minutes. You’ll likely awaken refreshed from this brief repose, and the caffeine will start to take effect, providing an extra boost. However, this technique may not be suitable for everyone, especially those who are sensitive to caffeine.

Regardless of how you do it, napping is for everyone, and it doesn’t have to be a source of frustration. By paying attention to timing, duration, and other factors, you can unlock the rejuvenating potential of a well-timed snooze.

How To Create the Perfect Sleep Soundtrack

The right environment is key to a restorative daytime slumber, and sound often plays a significant role. While some prefer complete silence, others find that certain types of background audio can be conducive to a restful sleep. White noise, nature sounds (such as rain or ocean waves), and ambient music can help mask clamorous distractions and promote better relaxation.

Others have even developed entire podcasts designed to help you fall asleep. Baseball fans might appreciate Northwoods Baseball Sleep Radio, where Wally McCarthy (a pseudonym) calls imaginary old-timey baseball games between imaginary teams, replete with imaginary players and even imaginary advertisers. There’s also Sleep With Me, where Scooter (a.k.a. Drew Ackerman) tells meandering stories in creaky dulcet tones. You’re not really missing anything if you lose track of what he’s saying—that’s actually the point.

For those who aren’t into podcasts, consider the BBC Shipping Forecast, where broadcasters calmly deliver weather reports for the seas around the British Isles. Each forecast is only a few minutes long, but YouTube videos stitch them together to create a napping soundtrack that spans hours.

Sugar, Sex and Your Health: The Connection You Might be Ignoring

Sugar, Sex and Your Health: The Connection You Might be Ignoring

Claremont Colonic Center
When most of us think about sugar, I bet we’re not thinking about our sex lives. We’re thinking about dessert. I’m writing this with the help of a bowl of vanilla ice cream by my side.
Sugar makes us feel good in the moment, but over time, too much of it may cause us to lose out on some of life’s most intimate moments.

In 2025, everyone’s been buzzing about GLP-1 injections to help control sugar and lose weight. This new class of medication has helped many achieve meaningful health gains — including improved blood sugar, weight loss — and even improvements to people’s sex lives (because they could be getting better sleep, too).

My goal here isn’t to discount the use of GLP-1 drugs or suggest people are taking them unnecessarily (although some people may be). My intent is to spark a broader conversation: What if we also paid more attention to the root cause: our love for sugar and its downstream effects on mood, metabolism, sex and more?

Is your blood sugar normal?

Most people associate blood sugar with diabetes, but few know what is “normal.”

Blood sugar levels can be checked in real time with a simple finger stick, via home glucose monitor or through wearable devices such as continuous glucose monitors (those coin-size devices you may see on people’s upper arms), which provide feedback on glucose levels throughout the day.

What do we see when this test is done? Following is the American Diabetes Association range of reference for blood glucose levels, but they are not meant for you to diagnose yourself with diabetes. In many instances, your provider may double- or even triple-check these numbers before labeling you with “diabetes.”

All numbers should be evaluated by your health care provider.

Fasting blood sugar (no food for at least eight hours prior):

  • Normal: below 100 mg/dL (milligrams per deciliter)
  • Prediabetes: 100 to 125 mg/dL
  • Diabetes: 126 mg/dL or higher


Random blood sugar (taken any time of day):

Diabetes is often diagnosed if levels are 200 mg/dL or higher with symptoms.

The point-of-care glucose test gives a snapshot, but there’s one lab that tells the full story — the hemoglobin A1c.

What is hemoglobin A1c, and why does it matter?

This blood test measures the percentage of hemoglobin proteins in your blood that have glucose attached to it — giving you and your health care providers a picture of your average blood sugar over the past two to three months. This makes it a reliable indicator of how well your body manages glucose over time.

Here’s how the American Diabetes Association breaks it down:

  • Normal: A1c below 5.7%
  • Prediabetes: 5.7% to 6.4%
  • Diabetes: 6.5% or higher


In my work as a surgeon, checking A1c before any procedure — especially those involving implants — is standard practice. Elevated A1c levels are strongly linked to poor recovery, infection risks and surgical complications. So, whether it’s a major urologic procedure or something else, keeping your glucose in check matters more than most people realize.

What high blood sugar does to your sex life

Sexual health is rarely the first thing people associate with blood sugar, but chronically high glucose levels can have an impact on intimacy — for everyone.

In men, high blood sugar can damage the nerves and blood vessels essential for achieving and maintaining erections. Over time, this can present as erectile dysfunction, before a man is ever diagnosed with or thought to be at risk for diabetes. High blood sugar can also lower testosterone levels, which then reduce libido and energy.

Many of my patients who do not get routine screenings from their primary care providers come to see me because of changes in sexual performance — only to later discover their blood sugar is out of control. For these patients, their first clue that something was wrong wasn’t thirst, weight changes or fatigue (the more common early signs of diabetes) — it was trouble in the bedroom.

In women, high blood sugar can lead to reduced blood flow and hormone imbalances, which may cause vaginal dryness, painful sex or problems with orgasm. It can also increase the risk of recurrent urinary tract infections, which can make intimacy painful or less appealing. Many women can feel frustrated and confused about whether these changes are expected from aging, post-menopause, stress or something else. A poor sugar level is usually the last thing on their mind.

How high blood sugar is treated

Diabetes is incredibly common — about 38 million Americans have it — and nearly 1 in 4 don’t even know it, according to the US Centers for Disease Control and Prevention. Traditionally, diabetes treatment started with oral medications like metformin, which helps lower glucose by reducing sugar production in the liver. Other classes of pills work in different ways, either by increasing insulin release or helping the kidneys flush out excess sugar. These medications are typically prescribed for people in the earlier stages of diabetes or with mildly elevated A1c.

Injectable medications may be necessary when oral pills aren’t enough to treat the disease. For years, that often meant daily insulin injections, which many patients found to be burdensome but necessary. Insulin needs to be carefully timed with meals, and dosing can be tricky. There’s also a real fear of low blood sugar episodes, which can make some people hesitant to start or stick with the therapy.

Over the past few years, GLP-1 receptor agonist drugs have become part of many people’s treatment regimens. This class of medication is known by names like semaglutide, liraglutide and tirzepatide. These injections mimic a natural hormone in your body that helps regulate blood sugar, slows down digestion and make you feel fuller faster.

While they were originally developed to treat type 2 diabetes, they’ve gained worldwide attention for helping people lose weight. In fact, many patients now ask and get these medications before any other option — not just to manage blood sugar, but to lose weight.

Better control over sugar can improve testosterone

These medications also may help normalize testosterone levels in men with obesity or type 2 diabetes, according to preliminary research presented at the Endocrine Society’s annual meeting this week.

Researchers tracked 110 men who were prescribed GLP-1 injections but were not taking any testosterone therapy. Over the course of 18 months, as participants lost on average about 10% of their body weight, the number of men with normal testosterone levels increased from 53% to 77%. This rise highlights how medications originally designed for diabetes and weight loss also may improve hormone levels in men.

While this abstract has not yet been peer-reviewed and more research is needed, these findings add to a growing body of evidence that managing weight and blood sugar can have ripple effects across nearly every aspect of health — including testosterone, energy and sexual function.

Try this harder alternative first

Before turning immediately to medications, don’t underestimate what consistent lifestyle changes can do, not just for your blood sugar but for your whole life.

Regular exercise improves insulin sensitivity, supports weight loss, boosts energy and even enhances sexual function by improving blood flow and hormone balance. A balanced diet — one that’s rich in whole foods, fiber and lean protein — can stabilize blood sugar and reduce inflammation that contributes to chronic disease. Better sleep, reduced alcohol and managing stress all play a role, too.

So, if you’re debating between an injection or a new routine, maybe this time reach for the gym bag before you try anything else. You might just find it changes more than your labs. It might change how you feel about yourself.

As for me, the next time I help myself to that scoop of ice cream while writing, I’ll remember that it’s not just about my waistline — it’s about my energy, my heart and my sexual health. And now that I’m done with this article, I’ll pick up my gym bag and walk the walk (to the gym) that I’m talking here.

The Super Scary Side of AI You’re Probably Ignoring

The Super Scary Side of AI You’re Probably Ignoring

ClaremontColonicCenter
AI is no longer just a fun chatbot or a tool that writes your homework. It’s rapidly morphing into something far more powerful—and potentially terrifying. While Big Tech continues to tell us that AI will make life easier, the darker side is hiding in plain sight.
First, there’s deepfake technology—AI can now clone your face and voice so convincingly that hackers can scam your grandma into wiring money or ruin someone’s life with fake “evidence.” One chilling example: criminals are already using AI voice cloning to pull off ransom scams, faking a child’s voice to extort panicked parents.

Then there’s surveillance. Governments and corporations are feeding AI mountains of your personal data. Every click, face scan, and location ping trains algorithms that track and predict your behavior. China’s AI-powered social credit system is just the beginning—imagine losing access to basic services because an algorithm labels you “untrustworthy.”

AI bias is another nightmare. Algorithms trained on flawed data can amplify racism, sexism, or political bias, deciding who gets a job, parole, or a bank loan. Worse, these systems are so complex that even their creators can’t always explain why they make certain calls.

And here’s the kicker: supercharged AI could outpace human control. Industry insiders, such as the so-called “Godfathers of AI,” are openly warning that powerful systems may act in unpredictable and dangerous ways. The fear? One day, AI could manipulate markets, spread misinformation that is impossible to stop, or develop goals that conflict with human survival.

While AI is transforming medicine and work for the better, ignoring its dark side is a gamble. If we don’t demand transparency and guardrails now, we might wake up one day to realize the machines aren’t serving us anymore—we’re serving them.
