Exercise has been shown to lengthen lifespan by as much as five years. A small new study suggests that moderate-intensity exercise may slow down the aging of cells. As humans get older and their cells divide over and over again, their telomeres—the protective caps on the end of chromosomes—get shorter. To see how exercise affects telomeres, researchers took a muscle biopsy and blood samples from 10 healthy people before and after a 45-minute ride on a stationary bicycle. They found that exercise increased levels of a molecule that protects telomeres, ultimately slowing how quickly they shorten over time. Exercise, then, appears to slow aging at the cellular level.
For urban runners and power-walkers, one of the biggest obstacles is other people. It’s difficult to get in your meditative zone and enjoy your music when you constantly have to dodge people. To resolve this vexing issue, Runbell, a startup in Tokyo, has developed the runner’s version of the bicycle bell. With this lightweight brass bell warning people you’re approaching from behind, you’re free to maintain your transcendental state while continuing your workout. Head to their Kickstarter campaign to pledge your support.
In addition to the direct beneficial effects of exercise on the heart, regular exercise also improves several important cardiac risk factors. Exercise lowers blood pressure, helps prevent obesity, reduces triglyceride levels, increases HDL cholesterol levels, and improves insulin resistance (and thus helps to prevent or even reverse metabolic syndrome ). An exercise routine has even been shown to be helpful in achieving smoking cessation.
Start the clock, and immediately do 10 reverse lunges in perfect form. When you’re done with the reverse lunges, go straight into jumping jacks until the clock reads 1:00 minute. Then move on to the next move. Do each move 10 times perfectly starting at the top of the minute, and finish out the minute with jumping jacks until it’s time for the next move. For the single-leg deadlift, do 10 on only one side (don't change your standing leg during any set of 10 reps).
Protein and fat loss go hand in hand. This nutrient supports muscle growth and raises your metabolism, making it easier to slim down. It also promotes satiety and reduces hunger, so you'll eat less without even realizing it. The American Journal of Clinical Nutrition states that high-protein diets can positively impact appetite, cardiometabolic risk factors, body weight and other factors.
Endorphins are hormones in the brain associated with a happy, positive feeling. A low level of endorphins is associated with depression. During exercise, plasma levels of this substance increase. This may help to ease symptoms of depression. A recent National Health and Nutrition survey found that physically active people were half as likely to be depressed.
For the greatest overall health benefits, experts recommend that you do 20 to 30 minutes of aerobic activity three or more times a week and some type of muscle strengthening activity and stretching at least twice a week. However, if you are unable to do this level of activity, you can gain substantial health benefits by accumulating 30 minutes or more of moderate-intensity physical activity a day, at least five times a week.
In addition to its other benefits, regular exercise helps older people remain independent by improving functional ability and by preventing falls and fractures (see also Exercise in the Elderly). It can strengthen the muscles of even the frailest older person living in a nursing or retirement home. It tends to increase appetite, reduce constipation, and promote quality sleep.
The high-intensity part of this workout is known as HIIT or high-intensity interval training. We're going to be using a 1/2-pound energy rope by CrossRope, which you can get for 10% off if you click that link. This rope, along with the heavy rope and agility rope, are what we use in every one of our videos and exercises because it's the best we've found on the market. This rope is a little heavier so it takes your fat burning to the next level. If you have a different jump rope that's cool too, just use the one you have. But by using a heavier rope, you're adding more resistance so you're going to burn more calories in less time. That's specifically why we're using this rope because we want to be as efficient as possible when looking to burn calories and fat loss.
You can also pair this workout with weight lifting in the gym to really work on building muscle. Some great arm toning exercises are simple exercises like triceps dips, pull-ups, and biceps curls. You can learn how to do these in our article on how to get cut arms. You can even do some rowing to get an intense workout for all of your arm muscles. If you want to take cardio up a notch to shed arm fat faster, check out our fat loss workout video that will get you on your way to getting shredded.
Many people who suffer from exercise-induced asthma, understandably try to avoid exercise. But sports medicine specialists say it's possible for asthmatics to continue exercising if they use preventive medications wisely and avoid certain triggers that exacerbate attacks. Exercise-induced asthma can be made worse by cold, dry air or air containing high levels of pollen or pollutants. The extra effort made to stay fit pays off in fewer or milder asthma attacks overall and a need for less medication.
Exercise helps people to lose and maintain weight. An exercise session burns calories and elevates metabolic rate both during exercise and then for hours after exercise is completed. It helps to preserve and build lean muscle mass. It works to suppress appetite. All of these benefits work together to make exercise vital for maintaining weight loss.
