In an era of prolonged screen time and desk jobs, sitting has been dubbed “the new smoking” — and for good reason. Our increasingly sedentary lifestyles are contributing to a surge in lifestyle-related diseases, particularly diabetes and cardiovascular issues. But a new study published in Diabetes Care offers a surprisingly simple way to counter this: take a 2-minute walk after every 20 to 30 minutes of sitting.

What the study found

The study found that people who interrupted their sitting time with short bouts of walking saw significant health benefits. Participants who took just 2 minutes to walk for every 20 to 30 minutes of sitting experienced:

• A 24–30% reduction in blood glucose levels
• A 23–26% drop in insulin levels

And this wasn’t dependent on weight, age, or fitness level. Even light-intensity walking was enough to create measurable improvements.

Why sitting for long periods is harmful

When you sit for hours at a time, your muscles become inactive, and your body’s ability to manage glucose is impaired. This leads to spikes in blood sugar and higher insulin resistance. Over time, this increases the risk of developing type 2 diabetes, heart disease, and other metabolic disorders.

Short, frequent movement reactivates muscle contractions, promotes glucose uptake, improves circulation, and reduces inflammation. It's a small effort with major returns.

Relevant for everyone — not just office workers

This rule isn’t just for desk-bound professionals. Whether you're a student, a homemaker, or someone who spends long hours in front of a screen, integrating short walks every half hour can make a meaningful difference to your long-term health.

No gym gear, no sweat — just 2 minutes of gentle motion like pacing around your room, stretching, or walking to refill your water bottle. It’s free, easy, and can be done anywhere.

The 20-8-2 rule: another approach to break up sitting

Alongside the 2-per-20 guideline, ergonomics experts also recommend the 20-8-2 rule to reduce the negative impact of sedentary work. Created by Alan Hedge, a Professor of Ergonomics at Cornell University, this rule suggests:

• 20 minutes of sitting
• 8 minutes of standing
• 2 minutes of light movement

This cycle encourages better posture, increased circulation, and more energy expenditure throughout the day. Research shows it improves cognitive performance and reduces fatigue — all without hurting productivity.

Yoga, at its heart, is a journey of balance, patience, and self-awareness. Yet, even regular practitioners can unknowingly fall into habits that limit progress or compromise the essence of the practice. Celebrity nutritionist Rujuta Diwekar, who works with stars like Kareena Kapoor, Alia Bhatt, Varun Dhawan, Saif Ali Khan and Karisma Kapoor, recently shared three common yoga mistakes that many of us make and how to correct them. Her advice is simple, practical, and rooted in tradition.

1. Always Starting With the Right Side

This habit, she explains, can unconsciously deepen the existing imbalances in the body. Yoga, after all, is a practice of samatva or balance. The aim is not to favour one side but to restore equilibrium—physically, mentally, and emotionally.

She suggests a simple correction. Yoga should be done with awareness. She says how even sitting postures like Sukhasana should be alternated to ensure both sides of the body are equally engaged. Start from the weaker or underused side. It may feel awkward initially, but over time, it helps realign the body and build balanced strength.

2. Only Practising the Asanas You Are Good At

This is a common pitfall. We gravitate towards what feels familiar and comfortable. But yoga is not meant to keep us within our limits; it is meant to gently stretch them. She encourages practitioners to explore the lesser-known asanas, especially those we tend to avoid, like backbends or twists. “We should go to their lanes, we should practise them, and we should have patience with ourselves. Little by little, every asana, especially backbends, will also come.”

She reminds us, “Yoga is not for show-offs. Yoga is for strength. For inner strength. This practice is not for outsiders.” It is a deeply personal journey, and real growth lies in consistency and courage, not perfection.

3. Skipping Practice When Time Is Short

But this is not how yoga works. “If you do not have time for 12 Surya Namaskars, then do 6. If you do not have time for 6, then do 3. But do it.” Even five minutes of mindful movement can bring enormous benefits. Over time, it is the commitment, not the duration, that matters most.

She also urges balance between the physical and the subtle. “If you are doing pranayama only every day, then do asanas also. If you are doing asanas only every day, then do pranayama once a month.” Her advice is to explore and embrace all aspects of yoga. That way, even if your routine is limited, it is never lopsided.

Yoga is not about being perfect in every pose. It is about showing up. “In your asana practice, explore the key aspects of yoga a little bit,” says Rujuta. “And give this gift of yoga to yourself in your lifetime.”

Whether you are a beginner or a seasoned yogi, her words are a gentle but firm nudge back to the basics. Do not let routine, comfort, or lack of time come in the way of your practice. As she sums up beautifully, yoga is a gift and one worth giving yourself every single day.

High-Intensity Interval Training or HIIT has become fitness’s darling for its efficiency: short sessions, intense output, and real results. You burn fat fast, build strength, and maybe even get a runner’s high without logging miles. Still, that thrill can hide a dilemma: doing HIIT every day may do more harm than good. Even as it offers potency, it also pumps up cortisol—the stress hormone—and that’s where things start to tilt.

According to fitness experts, high-intensity workouts trigger cortisol, elevating heart rate, breathing, and blood pressure. That’s fine in controlled bursts—it’s how HIIT pushes your body to adapt. But if your training cadence is relentless and stress from life piles on (say, the pandemic years), your body stays locked in fight-or-flight mode. What feels productive could quietly erode your metabolism, immunity, mood—and long-term health.

HIIT—high-intensity interval training—delivers power-packed bursts of effort, short recovery, and tangible results. You get calories burned, stamina boosted, and even mental focus sharpened in less time than traditional workouts but push too hard, too often, and your body begins to push back. Daily HIIT can shift from performance enhancer to internal stressor, if you're not careful.

Heart

HIIT is exceptional at improving cardiovascular efficiency. Studies consistently show gains in VO₂ max, improved blood vessel flexibility, and better insulin sensitivity—even more so than with steady-state cardio. HIIT reduces resting blood pressure and strengthens the heart’s pump function but when the heart is taxed day after day without rest, it can get overworked—especially if you already have an underlying condition. Overdoing it may result in undue stress on the heart, making symptoms like dizziness or chest tightness warning signs, not badges of dedication.

Metabolism

One of HIIT's biggest draws is the metabolic afterburn—or EPOC: your body brûle calories long after you've wiped the sweat away. It’s efficient, effective, and time-friendly. In studies, HIIT matches or surpasses moderate-intensity exercise in fat loss, waist reduction, and insulin sensitivity.³¹ But metabolic stress isn’t just positive. Without proper recovery, the gains plateau or reverse, especially if cortisol stays elevated.

Hormones and Cortisol

When you push your lungs and heart hard, your body ramps up cortisol—the fight-or-flight hormone. Short-term, that's fine but on a daily back-to-back schedule, cortisol becomes chronic. That’s when fatigue, irritability, sleep disruption, weight gain, and even immune suppression show up. Long-term HIIT without recovery doesn't just train your body—it stresses it.

Immunity Takes a Beating

Moderate exercise can boost your defences but constant high-intensity training changes the game- your immune system flags, white cells dip, and healing slows. In research and fitness communities, daily HIIT is linked to more colds, longer recovery, and increased inflammatory markers. That kind of vulnerability is a clear red flag.

Muscles, Joints and High-Impact Risk

Many HIIT workouts involve jumps, sprints, and explosive movements—all great for power, even better for injury risk. Your knees, ankles, shoulders, and back become targets if fatigue or poor form sets in. Routine high-impact HIIT plus weak stabilizers is a recipe for sprains or tendon issues. Recovery days—and movement diversity—are essential damage control.

Cellular and Mental Benefits

When used wisely, HIIT stimulates mitochondrial growth, boosting your cellular energy power. It sharpens cognitive function, supports mood, and improves overall endurance. But this adaptation happens in the recovery phase—not in the push. Without rest, your cells don’t strengthen—they stall.

Safe Way to Do HIIT Workouts

HIIT is one of the most effective training methods out there—it boosts endurance, burns fat, and saves time. But doing it daily without allowing your body to recover? That’s where it starts to backfire.

Pushing through fatigue may feel like dedication, but overtraining from constant HIIT can leave you sore, exhausted, and more prone to injury. Your muscles, joints, and immune system all need time to bounce back. And if they don’t get it, your performance declines—even if you’re working harder than ever.

Your body doesn’t get stronger during workouts; it gets stronger during rest. Recovery is when your muscles repair, your nervous system resets, and your gains actually lock in.

If you’re serious about results, treat recovery as part of the plan, not an afterthought. Two to three HIIT sessions per week, paired with rest or lower-impact training like strength, walking, or yoga, is more than enough for long-term progress. Listen to your body—fatigue, soreness, and poor sleep are signs you may be overdoing it.

Consistency is key, but so is knowing when to hit pause. That’s the real secret to sustainable strength.

Experts universally recommend 2–3 HIIT sessions per week—no more—with at least 24–48 hours between for recovery. That leaves room for walking, strength, flexibility, or restorative movement while giving your body time to adapt. Smart training means crafting a fitness week, not just firing off daily sprints.

HIIT works when you let it. Daily abuse wears you down. For lasting strength, resilience, and mental clarity, couple your intense interval sessions with recovery, variety, and respect. The gains you get may be invisible by the minute, but over time, they shape a fitter, stronger you.

In a move that has already sparked national debate, President Donald Trump signed an executive order reinstating the once-standard fitness benchmark for American students. The announcement, made alongside professional athletes like golfer Bryson DeChambeau and NFL star Harrison Butker, marks the revival of a decades-old program once intended to promote physical excellence in youth—but which has since drawn criticism for its mental and physical demands.

This return isn’t just about nostalgia. It’s part of a broader initiative that ties into Trump’s sports-focused agenda during his second term and America's preparation to host major sporting events such as the 2025 Ryder Cup, the 2026 FIFA World Cup, and the 2028 Summer Olympics. The rollout of the revived test will be overseen by Health and Human Services Secretary Robert F. Kennedy Jr., who has been vocal about what he calls the “childhood chronic disease crisis.”

The newly revived test is part of the “Make America Healthy Again” agenda championed by Kennedy. His May report emphasizes troubling trends: declining youth activity, climbing obesity rates, and increased incidence of chronic diseases in children. The executive order claims that these trends “weaken our economy, military readiness, academic performance, and national morale.”

Trump’s order reestablishes the President’s Council on Sports, Fitness, and Nutrition, instructing it to develop updated test criteria. It will partner with athletes, sports organizations, and public figures to create what the administration calls a “culture of strength and excellence.”

According to the order, declining fitness among American youth is “a threat to the vitality and longevity of our country,” particularly as the nation approaches its 250th birthday in 2026.

What Was the Presidential Fitness Test?

To understand why this announcement is stirring such heated debate, it's worth revisiting what the test actually involved.

The original Presidential Fitness Test was formalized in 1966 under President Lyndon B. Johnson but was rooted in a much earlier concern about American children's physical fitness. In the 1950s, orthopedic surgeon Hans Kraus and exercise expert Bonnie Prudden found that nearly 60% of American children failed their six-part strength and flexibility test—compared to fewer than 10% of European children. Their findings shocked President Eisenhower and led to the creation of the President’s Council on Youth Fitness.

Over time, the test evolved into a yearly challenge for students aged 6 to 17, usually featuring:

• A one-mile run to measure cardiovascular endurance
• Sit-ups performed within one minute
• Pull-ups or push-ups to test upper body strength
• Sit-and-reach flexibility assessments
• Shuttle run drills to evaluate agility

Students who scored at or above the 85th percentile received the prestigious Presidential Physical Fitness Award. Others received participation certificates.

Why It Was Scrapped in 2012?

Despite its long-standing legacy, the Presidential Fitness Test was phased out during the Obama administration. It was replaced by the Presidential Youth Fitness Program, which emphasized personal health goals over athletic performance. The change was backed by growing concerns around mental health, body image, and the test's "one-size-fits-all" approach.

Educators and health professionals had begun to criticize the test as an outdated model that humiliated students rather than encouraged them. The Centers for Disease Control and Prevention (CDC) reported that even while the test was in place, obesity rates continued to rise—from 13% in 1960 to 34% in 2008—calling into question its effectiveness.

Instead, the new program focused on achievable, individualized goals and health improvements, guided by modern science rather than outdated percentile charts.

Why Bring Presidential Fitness Test Back Now?

So why return to a system that was largely discredited? According to the administration, the decision is tied to more than just fitness—it’s about national identity.

The upcoming 250th anniversary of the United States and its hosting of global sporting events create a symbolic moment to spotlight strength, unity, and youth development. Trump’s team sees physical fitness as an avenue for national pride and global competitiveness, especially as statistics continue to show American youth falling behind in basic health markers.

Secretary Kennedy has also argued that the current generation is experiencing an unprecedented rise in chronic disease, inactivity, and poor dietary habits—problems he believes need stronger interventions than what current programs provide.

Although the exact criteria for the new test haven’t been released, the White House says it will retain some traditional components while modernizing the structure. DeChambeau, now chairing the President’s Council on Sports, Fitness, and Nutrition, has hinted that flexibility, endurance, and strength will remain central to the updated test.

Implementation may begin as early as the next academic year, although many details—such as whether participation will be mandatory, how the test will account for students with disabilities, and what changes might be made to avoid previous mental health criticisms—remain unclear.

Is This A Fitness Test or a Cultural Flashpoint?

For many, this isn’t just a test—it’s a reflection of deeper cultural tensions. Supporters argue the return of the Presidential Fitness Test is a much-needed wake-up call for a generation growing increasingly sedentary and disconnected from physical activity. Critics, however, see it as a regressive move that prioritizes performance over wellbeing.

Organizations like the American Academy of Pediatrics and National Association for Sport and Physical Education have yet to weigh in formally, but past criticism suggests skepticism. Questions remain about the scientific basis of the test, its potential mental health effects, and whether it will be implemented fairly across diverse school populations.

Bringing back the Presidential Fitness Test might appeal to those nostalgic for dodgeball days and presidential awards, but it also reopens debates that never really went away. At its best, the test was a motivator and a symbol of excellence. At its worst, it was a public performance of failure for students who didn’t fit the mold.
