What is your favourite arm day exercise? There's a good chance your answer is the dumbbell biceps curl. That is indeed a great answer but that excercise alone is not enough. If your goal is to build balanced arm muscle and strength, you'll want to pair your biceps work with a complimentary triceps movement. One of the best choices to do that is the skull crusher.

How To Do A Scull Crusher?

• Start by lying back on the bench. Don't arch your back—drive your shoulder blades into the bench, squeeze your abs and glutes, and keep your feet flat on the floor.
• Press the weight straight up above your chest. Your upper arm should be just past 90 degrees, at a 91 or 92 degree angle. Keep your wrists strong and a tight grip on the bar.
• Lower the weight slowly down to an inch above your forehead, moving only at the elbows. Don't allow your shoulders to shift forward; keep your upper arm still.
• Drive the weight back up (again moving only at the elbows), squeezing your triceps at the top.
• Keep these more detailed form tips from Samuel in mind during your skull crusher sets.

Here Are Few Things Your Should Know

No Arch: Maintain a sturdy body position: Feet flat on the floor, squeezing your glutes, and keep your core active so that you’re not arching your back on the bench. I know, I know; we always say you shouldn’t arch your back, but it’s more important to get the most out of the skull crusher. You want, at minimum a perpendicular upper arm angle relative to your torso; anything less than that, and your arm action misses the point of the skull crusher. If you arch your back, it’s harder to find that proper angle.

Shoulder Position: Once you have the bar over your head, drive your shoulders aggressively into the bench and maintain a little bit of tension in your mid-back. Then lean your upper arms back just slightly. Typically, you’ll see people aim to keep their upper arms perpendicular to the floor; I want you to be at a 91- or 92-degree angle instead. That slight shift places more tension on the triceps when you straighten your arms and prevents the straight-armed position from being a position of rest. Now you need to fully flex your triceps to maintain straight arms.

Elbows Tight: As you lower the weight, work to keep your elbows in. Your elbows and wrists should both be shoulder-width apart; not closer or farther apart. It’s common for people to let their elbows flare out as they’re doing skull crushers; avoid this. That’s a good way to injure your shoulders and it also takes emphasis off your triceps, diminishing the effectiveness of the move.

One Lever Only: Once you’ve gotten into this position, lower the bar to your head, moving only at the elbow joint. It’s tempting to let your upper arms roll back as you lower the bar toward your forehead, then shift your upper arms forward as you drive the weight back up, but that takes emphasis off your triceps and gets your lats involved. You’re aiming to move only at the elbows, maximizing the work your tris have to do.

Muscles Worked By Skull Crusher

The skull crusher is all about the triceps. The three-headed muscle, located on the back side of your arm, is the biggest muscle on the limb, making it an essential point of focus if you want to grow those guns. The name of the movement comes from the slightly precarious position you put yourself in to pull it off, isolating the muscles and moving the weight up and down directly above your head.

Benefits of Skull Crusher

The best triceps exercises put you in a good position to make use of the muscles' primary function: extension of the elbows. There are few better (or tougher sounding) moves to do this than the skull crusher. If you work with proper form, you'll isolate the muscles so that you're focused on only elbow extension. This will make your triceps stronger—which is essential for compound pushing exercises like the bench press—and spur muscle growth, too.

What Equipment You Need for Skull Crushers

The exercise is also fairly adaptable to the gear you have on hand. You can use dumbbells, a standard barbell, EZ bars, cable machines, and even your bodyweight to do skull crushers. For most of these variations you'll also need a bench, although you can perform the exercise prone on the ground, too. If you're low on equipment, you can do a bodyweight variation of the skull crusher that will provide the same type of triceps isolation, sans weights.

Walking is said to be one of the best exercises. Not only is it an easy and accessible exercise, but it can be done anywhere and also does not need a lot of equipment. Many people aim for 10,000 steps a day as a sign of good health. But should you take one long walk, or multiple short ones? A new study has answered this question.

New research suggests that a single, longer walk each day is better for your heart than breaking up your steps into many short strolls, especially if you don't exercise regularly.

The study, published in Annals of Internal Medicine, found that walking for at least 15 minutes without stopping is ideal. This longer, steady pace, which is about 1,500 continuous steps gives your heart a much better workout.

Longer Vs Shorter Walks: Which is Better?

Researchers tracked the walking habits of over 33,500 adults in the UK who walked less than 8,000 steps a day. After tracking their health for eight years, the findings were clear:

Lower Heart Risk

People who consistently walked in longer, uninterrupted stretches had a lower risk of heart problems compared to those who only took short, quick bursts of steps.

Why Are Longer Walks Better For Health?

Even among the least active group (those walking under 5,000 steps daily), taking longer walks made a major difference. Their risk of heart disease and early death dropped significantly.

The researchers explain that most people focus only on the number of steps they take, but not the patterns. They suggests that even inactive people can boost heart health by changing their habits to walk for at least 10–15 minutes at a time.

Should People Focus More On How They Walk Or How Much?

Many people aim for 10,000 steps a day, but that number actually came from an old pedometer advertisement, not science. While experts agree more steps are generally good, this study emphasizes that how you walk matters more than just the total step count.

The researchers suggest that simple changes, like setting aside time specifically for a long walk, could make a big impact on heart health.

The NHS still recommends getting 150 minutes of moderate activity like brisk walking, each week, and ideally it should be spread out. For older adults, moving every day, even with light activity around the house, is key.

It's important to know that while the study shows a strong link between longer walks and better health, it doesn't definitively prove that walking directly causes the improvement.

However, health experts agree exercise is vital. They explain that you might find it hard at first, but it will get easier as your body adjusts. Even small improvements contribute to a healthy heart.

What Are Some Safety Tips for Walkers?

While walking is generally a safe activity, accidents can happen, especially if you like to walk alone. To stay safe while walking,

Be Visible

Wear bright, reflective clothing or carry a flashlight after dark or in dim light so drivers and others can easily spot you.

Stay Alert

Focus on your immediate surroundings; avoid distractions like your phone or headphones to always know what's happening around you, especially traffic.

Use Paths

Walk or bike only on marked paths, lanes, or sidewalks, and cross streets at designated crosswalks where vehicles are expecting pedestrians.

Donald Trump health has become a heated topic of debate and the concerns around his health has resurfaced after a photo from his Kuala Lumpur visit on Sunday, October 26, went viral. He was spotted with swollen ankles. The photo that went viral is from a meting of the Association of Southeast Asian Nations (ASEAN), which kicked off his six-day trip.

The pictures of his swollen ankle have flooded on social media and people are saying that his ankle is seen to be extremely swollen. As per experts, this happens due to chronic venous insufficiency, which is a condition Trump had earlier announced to be suffering from.

Chronic venous insufficiency occurs when the veins in the legs have trouble sending back to the heart. This causes blood to pool and creating high pressure. This is usually caused by damaged or weakened valves in the veins and is characterized by symptoms like leg swelling, aching, and heaviness, which improves with elevation. Risk factors include age, a history of deep vein thrombosis, and prolonged periods of sitting or standing.

However, Trump's latest physical test says something else. The White House physician Sean P Barbabella declared that the president "remains in exceptional health, exhibiting strong cardiovascular, pulmonary, neurological, and physical performance". Barbabella also stated that his "cardiac age was found to be approximately 14 years younger than his chronological age".

Trump's Legs Could Also Reveal That He Had A Stroke

As per a "Physical Therapist", who posts videos on Instagram by the username @epistemiccrisis with 74.2k followers, Trump also had his peroneal nerve paralyzed. He explains, "The deep branch of common peroneal nerve, which supplies a muscle known as the tibialis anterior, which blends your foot up toward your head when you walk. This is known as dorsiflexion. If this nerve is paralyzed, you would get a foot drop."

However, he notes that this can be easily remedied with a brace, called ankle foot orthosis or AFO. He said that the president was most likely wearing it as the outline of the posterior portion of "what looks like an AFO" could be seen through his pants.

Concerns On Trump's Health

Previously, the same "Physical Therapist" claimed that President Trump had a stroke. This is because he had difficulty walking in a straight line. In fact, a 2021 study published in journal Healthcare notes that stroke is a major cause of disability worldwide and balance impairments are common disabling factors in patients with stroke, which could lead to falls.

However, as per the official medical records of the president, no such strokes were mentioned. His medical report pronounced him in "excellent health". The examination was done at Walter Reed National Military Medical Center. The report also emphasized that Trump maintains a "demanding daily schedule without restriction". Not only that, the report has gone so far to declare Trump's cardiac age as 14 years younger than his actual age after an electrocardiogram.

Dr Peter Attia, physician, and researcher known for his work in longevity medicine believes that there is a correlation between your grip strength and dementia onset risk and dementia mortality.

Dr Attia says, "My best explanation for this is that grip strength is itself a proxy for overall strength. The type of strength we are talking about here is acquired, not inherited. You had to do a bunch of work to get it, and it is the work you did that is actually what's protect your brain."

He says that women who are over 40, must be able to hand on a bar for a minute and a half, and for men, it is two minutes. The key is that you are supposed to be able to carry 75% of your weight, he says, in an interview with CBS News' 60 minutes.

Is There Any Truth In The Claim That Grip Strength Has A Correlation With Dementia?

As per a 2021 study published in journal Frontiers in Aging Neuroscience, titled Grip Strength and the Risk of Cognitive Decline and Dementia: A Systematic Review and Meta-Analysis of Longitudinal Cohort Studies, loss of grip strength and cognitive impairment are prevalent in the elderly, and they may share the pathogenesis in common.

The study found that poorer grip strength was in fact associated with more risk of cognitive decline and dementia. The subgroup analysis within the study also indicated that people with poorer strength had more risk of Alzheimer's disease and non-AD dementia.

But why does this happen? Lower grip strength is a marker for overall muscle mass, general health, and is linked to the health of the brain and its blood vessels. This link is also connected to other factors like vascular health, cognitive decline, and physical activity, as low grip strength can be a symptom of poor overall physical and metabolic health.

How Is Lower Grip Strength Is Linked To Dementia?

Indicator Of Overall Health: Grip strength reflects the health of entire body, this is why a lower grip strength is an indicate of lower muscle mass, and general poor health.

Vascular and brain health: Since there is a connection between muscle strength, blood flow, and brain health, thus lower grip strength is associated with a higher risk of vascular dementia and a greater volume of white matter hyperintensities in the brain.

Poorer grip strength is associated with lower cognitive function, such as fluid intelligence and prospective memory. This suggest a link between the body's physical capabilities and the brain's cognitive abilities.

A different study published in 2022, where 40,000 participants from the UK Biobank were studied found that greater grip strength was associated with better cognitive functioning, higher life satisfaction, greater subjective well-being, and reduced depression and anxiety symptoms while controlling for numerous demographic, anthropometric, and socioeconomic cofounders.

The study also found that grey matter volume of subcortical region also correlated with better mental health and considerably mediated their relationship with grip strength.
