Enhanced Bent-Over Row

[amazon_link asins=’B000HRRBBC,B00PW7RAHM,B00PJ7U8EM,B01M7PJ4TK’ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’e94dc3e7-4b94-11e7-9bf1-7fe1a9c4da2d’]

Here’s a challenging variation of the traditional bent-over row that will strengthen your core and your upper body muscles. Remember to hold lighter dumbbells while you master the technique, then increase the weight once you’re comfortable finding your balance. Practice patience because this exercise is harder than it looks.

Stand upright grasping a 3-, 5- or 8-pound dumbbell in each hand, with your arms hanging below your shoulders. Slowly begin to tilt your torso forward, bending at the hips. Bend your right knee slightly and shift your body weight off your left leg. Find your balance with just your left toes touching the floor behind you. Concentrate on keeping your shoulders, chest and hips facing squarely toward the floor.

When you feel ready, begin to raise your left leg off the floor until it reaches hip level. At the same time, bend your elbows and bring the dumbbells to your hips. Pause. Continue to hold your leg up as you lower and raise your dumbbells eight to 12 times. Return to an upright position and repeat, this time balancing over your left leg while lifting your right leg.

A recent study published in the journal Mechanisms of Aging and Development confirms the “anti-aging” effect of high-intensity training.

Telomere shortening occurs as you age, however the factors involved are not entirely understood as of yet. The study was conducted to determine whether age-associated telomere shortening is related to habitual endurance exercise and maximal aerobic capacity.

The results suggest there’s a direct association between reduced telomere shortening in your later years and high-intensity-type exercises.

The authors’ state:
“The results of the present study provide evidence that leukocyte telomere length (LTL) is related to regular vigorous aerobic exercise and maximal aerobic exercise capacity with aging in healthy humans.

LTL is not influenced by aerobic exercise status among young subjects, presumably because TL is intact (i.e., already normal) in sedentary healthy young adults.

However, as LTL shortens with aging it appears that maintenance of aerobic fitness, produced by chronic strenuous exercise and reflected by higher VO2max, acts to preserve LTL.

… Our results indicate that leukocyte telomere length (LTL) is preserved in healthy older adults who perform vigorous aerobic exercise and is positively related to maximal aerobic exercise capacity. This may represent a novel molecular mechanism underlying the “anti-aging” effects of maintaining high aerobic fitness.”

But that’s not all.
High-intensity interval-type training also boosts human growth hormone (HGH) production. A 2003 study published in the journal Sports Medicine found that “exercise intensity above lactate threshold and for a minimum of 10 minutes appears to elicit the greatest stimulus to the secretion of HGH.”

Regular Exercise Reduces a Large Number of Health Risks

[amazon_link asins=’B01K2R49IY,B01JTKD468,B00Z0YXVJS,B003MWQYSA,B01FQE2TYE,B01LWNBX0K,B01M0VAJMR,B00QAIRV6W,B06X9TVBB2′ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’4cca8834-4e49-11e7-9710-03d4c8917302′]

Regular exercise can reduce the risk and symptoms of more than 20 physical and mental health conditions, and can also slow down how quickly your body ages.

A review of research, which summarized the findings of 40 papers published between 2006 and 2010, found that exercise affects conditions including cancer, heart disease, dementia, stroke, type 2 diabetes, depression, obesity and high blood pressure.

Science Daily reports:
“… [A]part from not smoking, being physically active is the most powerful lifestyle choice any individual can make to improve their health.”

A separate study also found that women who exercise for 150 minutes a week or more could be reducing their risk of endometrial cancer, whether or not they are overweight.

Researchers examined data collected from a case-control study that included almost 700 women with endometrial cancer and compared them to a similar number of age-matched control women. Those who exercised for 150 minutes a week or more had a 34 percent reduced risk of endometrial cancer.

Newswise reports:
“This association was more pronounced among active women with a body mass index (BMI) less than 25, or underweight women, where the reduction in risk was 73 percent compared with inactive women with a BMI more than 25, or what is commonly considered overweight.

Although BMI showed a strong association with endometrial cancer, even women who were overweight, but still active, had a 52 percent lower risk.”

Controversial New Breakthrough Can Boost Your Child’s Health

There were once doubts that strength training held any benefits for children.  But a new research review confirms that children and teenagers can increase their muscle strength with regular workouts.
CLICK  & SEE
The findings support recent recommendations from the National Strength and Conditioning Association (NSCA) that kids strength-train two to three times a week under professional supervision.

Studies have shown that children’ICK & SEEs risk of injury from strength training is no greater than that from other types of exercise or sports, and the potential benefits of such training, such as increased bone density and decreased body fat, generally outweigh any risks.

Reuters reports:
“Overall … the training was effective at boosting kids’ strength, with gains being greater among older kids versus prepubertal children (typically about age 10 or younger) … The average strength gain varied widely among the studies, but in the majority the kids improved their strength by 20 percent to 40 percent of their starting levels.”

Pilates roll down

STRENGTHENING YOUR CORE WHILE  STRETCHING YOUR SPINE  :

Use this Pilates roll-down exercise to stretch and strengthen your core muscles. Leaning against a flat wall to perform the move helps you hold and maintain a C-curve shape to your spine.
…
Grasp a light dumbbell in each hand and stand with your back against the wall. Your shoulders and hips should touch the wall. Walk your feet forward, bend your knees slightly and firmly press your back into the wall. Let your arms hang below your shoulders.

Tuck your chin in toward your throat and begin to roll down until just your lower back and the back of your pelvis remain in contact with the wall. Pause at this point and focus on pressing your navel toward your spine as you move your arms in small circles six times. Pause and reverse the circles, keeping your arms loose. Roll up slowly, one vertebra at a time, and return to the start position.
