Another study this month, from Mayo Clinic, found that exercise in older people who were formerly sedentary had at least as strong an impact as in it did in young people—at least in the kinds of genes that were expressed. The study also found that these changes were much more robust in response to interval training than to weight lifting or moderate exercise. Which may mean that for some things, the type of exercise we chose matters.
Toning your arm muscles will certainly get you the definition you seek, but adding some extra protein to your diet will get you there even faster. Research published in The Journal of Nutrition reveals that packing on the protein increased muscle synthesis by as much as 25 percent, meaning that you can build stronger muscles faster, right in the privacy of your own home.
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.
Although the cardiovascular effects of exercise are partly related to inflammation, they still deserve their own category. Exercise is one of the best-illustrated things we can do for our hearts, and this includes markers like blood pressure and cholesterol, in addition the physical structure of the heart itself, and blood vessel function. Studies have suggested that 30 minutes per day is good enough to keep the heart in shape, while others have suggested we do more than this to get a real effect. Some have found that light activity is even enough to help the heart, but not all research confirms this, so it’s a little hard to tell how low levels of activity affect heart health over the long term. Additionally, too much exercise has also been shown to be stressful to the heart. So all this is to say that there’s probably a sweet spot somewhere in the middle for optimal cardiovascular health.
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.
No matter what exercise routine you choose, use the time to meditate. You may wonder how marathon runners are able to put so many miles on their bodies. It’s because the pain from running that you avoid is something they’ve learned to harness to enter a transcendental state. If you’re aware of the benefits of meditation and exercise but don’t have time to do both, you can combine them, killing two birds with one healthy stone.
First off, it is impossible to “spot reduce”, that is to lose fat from a specific area. When you do exercises that target a specific area, you’re actually targeting the muscles (not fat!) in that area. That means you’re doing step 2, which is increasing the shape and firmness of your arms by toning your arm muscles. That will get you some results, but fighting jiggly arms requires more than just spot exercises!
If you want to lose weight and keep it off, you know that exercise should be an essential part of your routine. But the benefits of physical activity go far beyond just physical fitness. Increasingly, more and more research is showing that working out regularly can boost other aspects of your health as well, including cognitive function and emotional well-being.
