9 Least Effective Exercises


Workout Not Working?

Who has time to waste on ineffective, risky exercises? Not you. So ditch these nine moves that may not deliver the results you want 

#1: Lat Pull-down Behind the Head

The problem: Only people with very mobile shoulder joints can keep their spines straight enough to do this exercise properly. So the move — done wrong — can lead to shoulder impingement or worse, a tear in the rotator cuff. And if the bar hits the back of the neck, it could injure cervical vertebrae.and may even cause injury

#2: Military Press Behind the Head

This shoulder move, in which you lift weights or a barbell up and down behind the head, can cause the same problems as the lat pull–down behind the head.

#3: Upright Row

The problem: Pulling weights, a barbell, or a weighted cabled bar up under your chin is a big no-no because it can compress the nerves in the shoulder area, impinging the shoulder.

#4: Leg Press with Poor Knee Position

From a reclining position, you push the plate up and bring it down in this common exercise to work the quadriceps, hamstrings, and glutes. The problem comes when you bend your legs too far -- past a 90-degree angle -- which can hurt your back and knees.

#5: Squats on the Smith Machine

The problem: The bar on the machine doesn't give, which can force the body into risky positions. Plus, people tend to put their feet farther in front of their bodies when doing squats on the machine, which makes matters worse.

#6: Bad Form on Cardio Machines

The problem: Hunching over or using a death-grip on the handrail cheats your body and can throw off your alignment, jarring your spine, shoulders, and elbows

#7: Exercises for Spot Reduction

People who do strengthening and toning exercises in an effort to trim fat from a certain area -- thighs, hips, stomach, or arms -- have the wrong idea. Although these exercises can help firm muscles, if the targeted area still carries an extra layer of fat, it won't look much different. You can't isolate fat loss to one part of the body.

# 8: Always Lifting with a Weight Belt

The problem: Too many people wear weight belts too often. Unless you have a back injury or other medical reason -- or are lifting a lot of weight -- the weight belt may let your core muscles slack off. And you need your core muscles all the time in everyday life.

The solution: Back off the weight belt unless it's necessary.

#9: Exercising in the Wrong Shoes

Even if you're doing everything else right, your efforts can be undermined by improper footwear. Working out with the wrong shoes increases pounding on the joints, and can lead to injuries like plantar fasciitis or tendonitis.

Things You Can Learn from Your Pets



Take Naps

You won't catch your pet going from dawn to dusk without any shut-eye.  There's good evidence humans can benefit from catnaps, too. A study involving about 24,000 people indicates regular nappers are 37% less likely to die from heart disease than people who nap only occasionally. Short naps can also enhance alertness and job performance.
Walk Every Day
Whether you've got four legs or two, walking is one of the safest, easiest ways to burn calories and boost heart health. Taking regular walks can also help you:
·         Fight depression.
·         Lose weight.
·         Lower your risk for type 2 diabetes.
·         Lower the risk of breast and colon cancer.
·         Keep your bones strong.
·         Keep your mind sharp.

Cultivate Friendships

People are social animals, and friendships have measurable health benefits.  Researchers in Australia followed 1,500 older people for 10 years. Those with the most friends were 22% less likely to die than those with the fewest friends.  

Live in the Moment

Living in the moment may be one of the most important lessons we can learn from our pets. In a study called "A Wandering Mind Is an Unhappy Mind," Harvard psychologists conclude that people are happiest when doing activities that keep the mind focused, such as sex or exercise. Planning, reminiscing, or thinking about anything other than the current activity can undermine happiness.

 

 

 

Don't Hold a Grudge

Part of living in the moment is letting bygones be bygones. Let go of old grudges, and you'll literally breathe easier. Chronic anger has been linked to a decline in lung function, while forgiveness contributes to lower blood pressure and reduced anxiety. People who forgive also tend to have higher self-esteem.

Wag

OK, so maybe you don't have a tail. But you can smile or put a spring in your step when you're feeling grateful. Researchers have found a strong connection between gratitude and general well-being. In one study, people who kept gratitude journals had better attitudes, exercised more, and had fewer physical complaints.

Maintain Curiosity

According to a popular saying, curiosity may be hazardous to a cat's health. But not so for humans. Researchers have found that people who are more curious tend to have a greater sense of meaning in life. Other studies have linked curiosity to psychological well-being and the expansion of knowledge and skills.

Be Silly

Indulging in a little silliness may have serious health benefits. Cardiologists at the University of Maryland Medical Center found a stronger sense of humor in people with healthy hearts than in those who had suffered a heart attack. They conclude that "laughter is the best medicine" – especially when it comes to protecting your heart.

Get a Back Rub

The power of touch is nothing to sniff at. The Touch Research Institute at the University of Miami Miller School of Medicine has found massage therapy can ease pain, give the immune system a boost, and help manage chronic conditions like asthma and diabetes. The touch of a loved one may be even more powerful. In one study, married women experienced less anxiety over the threat of an electric shock when they held their husbands' hands.

Drink Water When You're Thirsty

Dogs don't lap up sports drinks when they've been playing hard – and most people don't need to either. During a typical workout, drinking water is the best way to stay hydrated. Water gives your muscles and tissues critical fluid without adding to your calorie count. Be sure to drink more than usual on hot days or when you're sweating a lot.

Eat Fish

Most cats would trade kibble for a can of tuna any day. Luckily, you can choose to make fish a regular part of your diet. Salmon, tuna, trout, and other fatty fish are high in omega-3 fatty acids, which may reduce the risk of heart disease, high blood pressure, and arthritis. In addition, Rush University researchers found that people who eat fish at least once a week are 60% less likely to develop Alzheimer's disease.

If You Love Someone, Show It

Dogs don't play hard to get – when they love you, they show you. It's a good approach for people seeking to strengthen their relationships. A study published in the journal Personal Relationshipssuggests small, thoughtful gestures can have a big impact on how connected and satisfied couples feel.

Play

Goofing off is not just for kids and kittens. In his book, Play, Stuart Brown, MD, writes that playing is a basic human need along with sleeping and eating. Play enhances intelligence, creativity, problem-solving, and social skills. So take a cue from your pet and devote yourself to an activity that has no purpose other than sheer fun.

Enjoy the Great Outdoors

A hike in the woods may be a dog's idea of bliss, but it has plenty of benefits for the human mind and body as well. Spending time outdoors can enhance fitness, increase vitamin D levels, and reduce stress. In children, playing in natural settings has also been linked to better distance vision, fewer ADHD symptoms, and better performance in school.

Make Time to Groom

Aside from the obvious health benefits of bathing and brushing your teeth, grooming can have a number of positive effects on your life. Good personal hygiene is vital to self-esteem. A tidy appearance can also help you get and maintain a job.

Be Aware of Body Language

Dogs are excellent at reading each other's intent from body language. Humans, not so much. While most of us do reveal our emotions through posture, speech patterns, and eye contact, other people generally aren't very good at reading those cues. People get better at decoding body language as they get older.

Stretch Often

Stretching will keep you limber, but the benefits don't stop there. In a 10-week study, volunteers who did no exercise other than stretching experienced surprising physical changes. Besides improving flexibility, they increased their muscle strength, power, and endurance. Although the study was a small one, the results suggest stretching may be a good alternative for people who have a condition that rules out traditional strength-training.

Stick to a Schedule

Pets like the consistency of a routine – they can’t tell a Saturday from a Monday. The same goes for the human body clock. People sleep better if they go to bed and get up at the same time every day, even on weekends. Sticking to a consistent schedule for bathing, dressing, and eating can also improve the quality of sleep.

What your feet can tell

Cold Feet, Many Culprits
If your toes are always cold, one reason could be poor blood flow -- a circulatory problem sometimes linked to smoking, high blood pressure, or heart disease. The nerve damage of uncontrolled diabetes can also make your feet feel cold to you. Other possible causes include hypothyroidism and anemia. A doctor can look for any underlying problems -- or let you know that you simply have cold feet.

Red, White, and Blue Toes

Raynaud’s disease can cause your toes to turn white, then bluish, and then redden again and return to their natural tone. The cause is a sudden narrowing of the arteries, called vasospasms. Stress or changes in temperature can trigger vasospasms, which usually don’t lead to other health concerns. Raynaud’s may also be related to rheumatoid arthritis, Sjögren’s disease, or thyroid problems.

Dragging Your Feet

Sometimes the first sign of a problem is a change in the way you walk -- a wider gait or slight foot dragging. The cause may be the slow loss of normal sensation in your feet, brought on by peripheral nerve damage. About 30% of these cases are linked to diabetes. Nerve damage also can be due to infection, vitamin deficiency, and alcoholism. In many cases, no one knows what caused the nerve damage.

Clubbed Toes

In clubbing, the shape of the toes (and often the fingers) changes. The nails are more rounded on top and curve downward. Lung disease is the most common underlying cause, but it also can be caused by heart disease, liver and digestive disorders, or certain infections. Sometimes, clubbing runs in families without any underlying disease.

Swollen Feet

This is usually a temporary nuisance caused by standing too long  or a long flight -- especially if you are pregnant. In contrast, feet that stay swollen can be a sign of a serious medical condition. The cause may be poor circulation, a problem with the lymphatic system, or a blood clot. A kidney disorder or underactive thyroid can also cause swelling. If you have persistent swelling of your feet, see a physician.

Burning Feet

A burning sensation in the feet is common among diabetics with peripheral nerve damage. It can also be caused by a vitamin B deficiency, athlete’s foot, chronic kidney disease, poor circulation in the legs and feet (peripheral arterial disease), or hypothyroidism. 

Sores That Don't Heal

Foot sores that will not heal are a major warning sign for diabetes. Diabetes can impair sensation in the feet, circulation, and normal wound healing, so even a blister can become a troublesome wound. Those sores also are prone to infection. Diabetics should wash and dry their feet and check them for any wounds every day. Slow-healing of sores also can be caused by poor circulation from conditions such as peripheral artery disease.

Itchy Feet

Itchy, scaly skin may be athlete’s foot, a fungal infection that's common in men between the ages of 20 and 40. A reaction to chemicals or skin care products -- called contact dermatitis -- can cause itching, too, along with redness and dry patches. If the skin on your itchy feet is thick and pimple-like, it may be psoriasis, an over-reaction of the immune system. Medicated creams can relieve the symptoms.

Claw Toe

This foot deformity can be caused by shoes that are tight and pinch your toes or by a disease that damages nerves, such as diabetes, alcoholism, or other neurological disorder. Your toes will be bent upward as they extend from the ball of the foot, then downward from the middle joint, resembling a claw. They may respond to stretching and exercises of the toes or you may need special shoes or even surgery.

Foot Spasms

A sudden, sharp pain in the foot is the hallmark of a muscle spasm or cramp, which can last many minutes. Overwork and muscle fatigue are common causes. Other causes include poor circulation, dehydration, or imbalances in potassium, magnesium, calcium, or vitamin D levels in the body. The changing hormone levels of pregnancy or thyroid disorders may play a role. If spasms are frequent or severe, see a doctor. Strengthening exercises can help with muscle fatigue.

 

 

Dark Spot on the Foot

We associate skin cancer with the sun, so we’re not as likely to check our feet for unusual spots. However, a melanoma, the most dangerous form of skin cancer, can develop even in areas that are not regularly exposed to the sun. Melanoma can even appear beneath the nail, where it might look like a black spot.

Yellow Toenails

Your toenails tell a lot about your overall health. A fungal infection often causes thickened yellow toenails. Thick, yellow nails also can be a sign of an underlying disease, including lymphedema (swelling related to the lymphatic system), lung problems, or rheumatoid arthritis.

Spoon-shaped Toenails

Sometimes an injury to the nail or frequent exposure to petroleum-based solvents can create a concave, spoon-like shape. However, iron deficiency also can cause this unusual shape.

Exercise and High Blood Pressure


High blood pressure affects about 1 in 3 American adults and increases your risk of heart disease and stroke. Exercise, weight management, and a healthy diet are important ways to help prevent high blood pressure. Working out also boosts the effectiveness of blood pressure medication if you’re already being treated for hypertension. Be sure to check with your doctor before starting a fitness program.

Put the Fun Back in Exercise

Find activities you enjoy and aim for 30 minutes a day of “exercise” on most days of the week. Daily housework, gardening, washing windows, using the stairs, carrying your groceries, walking at the mall, or riding bikes with the kids all add up to exercise that benefits your heart.
Tip: Increase activity by parking at the end of the lot, or get off the bus a stop early and walk to your destination.

Hit the Gym

You don’t need to belong to a gym to become more active. But some people find it easier to focus on their workout in a gym setting. As an added bonus, the trainer at your local fitness center can teach you how to use the equipment properly to avoid injury. If any move feels wrong, check with your trainer. Depending on your health and physical condition, some exercises may not be recommended.

Strengthen Your Heart

Resistance exercise can be done with in many ways, such as with free weights, weight machines, exercise bands, or by doing abdominal crunches or curl-ups.  Resistance training helps reduce body fat, increase muscle mass, and boost your metabolic rate. Losing as little as 10 pounds can reduce or help prevent high blood pressure in many overweight individuals. Check with your doctor before starting a new weight-training program.

Can’t Take the Heat? Then Swim

Heart-pumping conditioning exercise is important for lowering blood pressure. But if you can’t take the heat, try swimming at your local “Y” or fitness center. Swimming for 30 minutes reduces the amount of circulating adrenaline in the body and relaxes blood vessels. Swimming can help lower your pulse rate and lower blood pressure.

How Much Exercise Is Enough?

Regular exercise may prevent or control high blood pressure. Moderate-level aerobic activities, such as brisk walking, for 30 minutes a day may be enough to keep you off medications or help them work more effectively. Exercise can reduce your blood pressure readings by as much as 5-15 points. Gradually increase the intensity of your workout to continue lowering your blood pressure to safer levels.

Getting Started

Haven’t exercised in a while? Start slowly to prevent injuries. Start with 10 to 15 minutes of exercise you enjoy, such as walking around the block or on a treadmill. As you get stronger, increase the time and intensity of your workout until you reach the goal of 30 minutes each day. Avoid sudden vigorous exercise or cramming your workout routine into a couple days in an attempt to catch up, which can lead to injury.

Pace Yourself to Avoid Injury

If you’re new to exercise, remember to pace yourself. Select a low- to moderate-intensity exercise such as yoga, cycling (leisurely), gardening, mall walking, water aerobics, or swimming (moderate pace). Gradually increase the intensity and duration of exercise as you become fitter to help maintain your lowered blood pressure.

Make Exercise Convenient

Make sure exercise fits your busy schedule. You can work out while the kids are at soccer practice, before or after work, or even during your lunch break. If it’s hard to get out of the house, consider getting a stationary bike or treadmill to use while watching the evening news or while the baby naps.

Warm Up and Cool Down

According to the American Heart Association, warming up before exercise and cooling down after are important for people with high blood pressure. These exercises let your heart rate increase and decrease gradually. Walking in place or on a treadmill for 10 minutes is fine for warming up before exercise and also for cooling down.

Know the Safety Tips

No matter what exercise you do, be aware of your limitations. If the exercise or activity hurts, then stop! If you feel dizzy or have discomfort in your chest, arms, or throat, stop. Also, go slower on hot and humid days or exercise in an air-conditioned facility.

See Your Doctor Regularly

Getting your doctor’s approval before starting a fitness program is important if you are sedentary, overweight, or have a high risk of coronary heart disease or other chronic health problem. It’s important to have your blood pressure measured by a health care professional, who can advise you as to how often to have it rechecked. Don’t wait for unreliable signs such as headaches, a red face, or stress to tell you your blood pressure is too high.
