We're all familiar with what to expect from a good workout- muscle ache, pounding heart, perhaps the pleasure of a runner's high if we're fortunate. But what about those odd, surprise sensations that creep upon you halfway through your sprint or in that final set of squats?

We all have strapped on sneakers and hit the road for the first time in years with a humble expectations, perhaps burning lungs, a little jelly legs, and a good reminder that school cross country was a distant memory. What people weren't prepared for, 15 minutes into the run, was a sudden toothache—yes, tooth pain, in the middle of cardio.

That run was the beginning of a closer investigation. Turns out, plenty of people have weird, even terrifying, physical symptoms while working out—and usually, it's your body just giving the whole system a check-up. Some of these symptoms are benign oddities, some may be indicators of issues that need to be taken more seriously. Here are five of the weirdest sensations people report when exercising—and what your body may be trying to communicate.

1. Tooth Pain While Running

Toothache during cardio could sound out of the ordinary, but it is quite more prevalent than you would imagine. Specialists have not identified a specific reason, but they provide some believable reasons.

First, there's the issue of sinus pressure. Your sinus cavities sit right above your upper teeth, and during intense aerobic activity—when you’re breathing fast and hard—those sinuses can become inflamed or irritated, especially if you’re already fighting off a cold or allergies. This pressure can cause the sensation of toothache even when your teeth are perfectly healthy.

Theory number two? You may be unconsciously clenching your jaw during hard work. As we grip the steering wheel harder when anxious, we can tense up the facial muscles and jaw during effort. As a result, we may get referred pain in our teeth. If this is an on-going problem, attempt to calm down while working and relax the jaw—alternatively, try a custom mouthguard on cardio days.

2. Metallic Taste in the Mouth

If you’ve ever been in the middle of a hard workout and suddenly noticed a weird metallic taste, you’re not alone—and no, it’s not your pre-workout supplement kicking in.

That strange taste may be due to small amounts of blood from inflamed mucous membranes in the nose or throat, says sports medicine doctor Dr. Timothy Miller. Long runs or interval training at high intensities can inflame or even cause slight bleeding of the sensitive linings of these regions. And the end result? A mouth full of coppery strangeness.

There is also the risk of lung capillary stress. On intense cardiovascular exertion, some red blood cells can leak into the lung air sacs, especially in top athletes or those going beyond their threshold. The taste is usually transient and benign—but it may also be your body shouting, "Hey, take it easy."

3. Itchy Skin (Also Known as Runner's Itch)

Few things derail a run faster than the urge to stop and scratch your legs mid-stride. If you’ve ever felt like your skin is crawling during a jog, you’ve likely encountered what’s commonly called runner’s itch.

While not completely explained, professionals attribute this feeling to the increased blood supply during cardio. Because your heart is beating harder, capillaries dilate to send oxygenated blood to muscles. This dilation activates surrounding nerve endings, causing itching—particularly in areas such as the thighs, stomach, or arms.

Runner's Question was generally harmless and transitory. It would be more pronounced among individuals resuming fitness, while the circulatory system was re-adapting to the pressure. If it hangs on or is joined by swelling and hives, see a doctor—it is likely an exercise-induced urticaria, an uncommon but real phenomenon.

4. Nose Pain

A drippy nose during exercise, particularly in cold air, is to be expected. But what about genuine nose pain or sinus pressure?

This is due to a condition referred to as non-allergic rhinitis, most commonly caused by dry air, pollution, or changes in temperature. With exertion, speed of breathing forces air straight into your nasal passages. If the air is particularly cold or contains irritants such as smoke or pollen, it can provoke inflammation and pressure in the sinuses, leading to pain or discomfort in the face and upper nose.

Although not harmful, this sensation is uncomfortable. Hydration, saline nasal spray, or masks in contaminated settings can all minimize the effect.

5. Numb Fingers

Numbness or paresthesia in your fingers while exercising—particularly cardio or warm-ups involving arm use—can be unsettling. Oftentimes, the offender is not your hands but rather poor posture or compression of nerves further up the body.

When your upper back, shoulders, or neck muscles are tight or weak—"tech neck" from hunching over a computer keyboard, for example—then it can pinches the nerves that run down into your arms. With increased blood flow, muscles start to contract and move, and these nerves become slightly pinched, leading to tingling or numbness.

This feeling can also be caused by tension-related muscle imbalances, particularly if you are overcompensating on one side or neglecting upper-body stretching. If it lasts longer than the workout or happens often, it is probably time to go see a physical therapist or doc to eliminate more problematic conditions such as thoracic outlet syndrome or pinched cervical nerves.

When to Pay Attention and When to See a Doctor

Feeling odd during exercise can be disturbing. In most instances, they're benign and can be attributed to the body adjusting to stress, blood flow changes, or environmental factors. If these persist, increase in intensity, or are accompanied by extreme pain, dizziness, or shortness of breath, see a medical expert.

Your body has a great way of providing you with feedback—if you pay attention. Tuning in to what these odd feelings may be trying to tell you can assist you in problem-solving smarter, remaining injury-free, and having fun along the route to fitness without unwarranted alarm.

For people spending too much time on social media, fitness often takes a back seat—and not for the best. If you are someone who is new to the gym, one of the most difficult parts of the regimen is performing and holding a plank for long enough. Planks are among the most effective workouts for a stronger core and for better management of belly fat. Yet, holding one for even a minute can become a herculean task, even for younger individuals. But for people in their 20s, what is the ideal duration for holding a plank? Let’s find out.

What are the benefits of planks?

Experts say planks are very effective for strengthening the core, as they engage multiple muscles at once, such as the following:

1. Obliques (sides)
2. Rectus abdominis (the front of your abdomen)
3. Transverse abdominis (the deep, stabilising muscles that wrap around your midsection)

Unlike ab exercises like crunches, planks target multiple muscle groups at once. This workout also helps stabilise the core while moving. It is effective for maintaining proper alignment during movement and for protecting the lower back. Experts say that, alternatively, lifting boxes at home is more or less the same as loading and unloading boxes from your car to your home. This emphasis on stability becomes more important with age.

In a 2012 study, older adults who successfully completed a nine-week core stability programme reported better spinal mobility, improved trunk strength, and enhanced dynamic balance. These factors collectively reduce the risk of falls. However, experts warrant caution, stating that focusing too much on plank duration could make the workout less effective. Instead, there is a good reason to strive for steady form and, over time, better endurance.

How long should you be able to hold a plank?

Timing a plank is not a one-size-fits-all approach. Several factors can influence how long one can hold a plank position, including overall fitness; body weight and proportions; as well as experience with planks and other breath control and muscular endurance exercises. Fitness experts say that age plays a significant role when it comes to plank duration. As one gets older, natural changes such as weaker joints and a decrease in muscle mass and strength can affect how long a plank can be maintained. Consistent training can help increase this duration.

While there is no specific number that everyone must aim for, people should try to improve their plank duration based on their age. Take a look at the ideal duration of holding a plank across age groups:

1. 18–39 years: 45–99+ seconds for the general population; 1–2 minutes for fitter individuals
2. 40–59 years: 30–75 seconds for the general population; 45–90 seconds for fit individuals
3. 60+ years: 20 seconds to one minute for the general population; 30–75 seconds for fitter individuals

High blood pressure (BP) has become a public health problem that is driving cardiovascular diseases like heart attacks and strokes globally. While medications are important to keep hypertension under control, lifestyle changes and healthy practices are also crucial.

Several global health guidelines recommend regular physical activity, but adhering to exercise programs daily becomes a challenge for many people. But in the overtly busy schedules, sparing 10 minutes for an exercise regimen can be easier than travelling to the gym.

A large randomized clinical trial, published in the Journal of the American College of Cardiology (JACC), has proved that a traditional Chinese mind-body practice — baduanjin — may help lower blood pressure, that too, without any equipment.

Baduanjin is a slow, structured movement, focused on deep breathing and meditation.

Importantly, the clinical trial proved that the ancient Chinese technique could lower BP as effectively as brisk walking.

In people practicing baduanjin, BP reductions were seen after three months and were sustained for one year.

"Given its simplicity, safety, and ease with which one can maintain long-term adherence, baduanjin can be implemented as an effective, accessible, and scalable lifestyle intervention for individuals trying to reduce their blood pressure," said Jing Li, Director, National Center for Cardiovascular Diseases in Beijing, China.

Baduanjin: The 10 Minute Routine

Baduanjin is a standardized eight-movement sequence that integrates aerobic, isometric, flexibility, and mind-body components.

It has been in practice for centuries and commonly performed in community settings across China. The routine typically takes 10–15 minutes and requires no equipment and only minimal initial instruction.

Because it is low- to moderate-intensity, it is considered safe and accessible for many adults.

The Clinical Trial

A team of Chinese researchers led the first large, multicenter randomized trial to look at the impact of baduanjin on blood pressure.

They followed 216 participants, aged 40 years or older, across seven communities to determine changes in 24-hour systolic BP from baseline to 12 and 52 weeks.

Compared to people indulging in self-directed exercise, practicing baduanjin five days a week reduced

• systolic blood pressure by approximately 3 mg Hg
• systolic blood pressure by 5 mg Hg.

Notably, the benefits were sustained even without ongoing monitoring, a key challenge for many lifestyle interventions that struggle to maintain long-term adherence outside structured programs.

"Baduanjin has been practiced in China for over 800 years, and this study demonstrates how ancient, accessible, low-cost

approaches can be validated through high-quality randomized research," said Harlan M. Krumholz, Editor-in-Chief of JACC and the Harold H. Hines, Jr Professor at the Yale School of Medicine.

"The blood pressure effect size is similar to that seen in landmark drug trials, but achieved without medication, cost, or side effects. This makes it highly scalable for community-based prevention, including in resource-limited settings," they added.

How To Practice Baduanjin

• Stand upright with your feet shoulder-width apart and keep your movements slow and controlled.
• Coordinate each motion with steady, deep breathing, inhaling and exhaling smoothly as you move.
• Move through the traditional eight postures in sequence, focusing on posture, balance, and relaxation rather than speed or force.
• Practice for about 10 to 15 minutes a day in a quiet space, maintaining calm attention throughout.

If you believe only gym workouts matter, you might be mistaken. While gyms offer a structured space to exercise, busy schedules often lead many to skip workouts—and feel guilty about it.

However, a new study suggests that even short bursts of vigorous everyday activity—such as running to catch a bus or climbing stairs quickly—can significantly reduce the risk of several major diseases and even lower the risk of death.

The research, based on nearly 96,000 people and published in the European Heart Journal, found that just a few minutes of intense activity each day was linked to a lower risk of:

• Major cardiovascular disease
• Irregular heartbeat
• Type 2 Diabetes
• Immune-mediated inflammatory diseases
• Liver disease
• Chronic respiratory diseases
• Chronic kidney disease
• Dementia

“We know that physical activity reduces the risk of chronic disease and premature death, and there is growing evidence that vigorous activity provides greater health benefits per minute than moderate activity,” said Minxue Shen from the Xiangya School of Public Health, Central South University, China.

Longer Workouts or Intense Bursts?

To explore whether exercising more intensely offers greater benefits than simply exercising longer, the researchers followed 96,408 participants for seven years.

Each person wore a wrist-based accelerometer to track movement, including short bursts of activity often overlooked.

The findings showed that compared to those who did no vigorous activity, participants with the highest levels had:

• 63 percent lower risk of dementia
• 60 percent lower risk of type 2 diabetes
• 46 percent lower risk of death

“Our findings suggest that adding short bursts of activity that make you slightly breathless—like climbing stairs quickly or walking briskly between tasks—can have substantial health benefits,” Shen said.

“Even 15–20 minutes per week, just a few minutes a day, can make a meaningful difference,” the Professor added.

Is Vigorous Activity Safe for Everyone?

The World Health Organization (WHO) recommends that adults (18–64) perform at least 150–300 minutes of moderate-intensity aerobic physical activity, or 75–150 minutes of vigorous-intensity activity per week.

The new study suggests that intensity also plays a key role—and may vary depending on the disease being prevented.

The researchers noted that these findings could help shape more personalised exercise recommendations in the future. However, they cautioned that vigorous activity may not be suitable for everyone, particularly:

• Older adults
• People with certain underlying medical conditions.
