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 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.
Stretch your arms to the side and bring them back to your front, the right hand should overlap the left. This resembles an open scissors. You need to stretch them to the side again and bring them back to the front. This time your left arm should overlap your right. This is a complete rep and this exercise needs to be done in 3 sets of 10 reps every day.
Research is finding that as we age, exercise may be able to help keep our brains healthy. Three studies presented at the 2015 Alzheimer’s Association International Conference showed that regular exercise may play an important role in protecting your brain from Alzheimer’s disease and other forms of dementia, and may help improve brain function and symptoms such as depression or anxiety in those who have these conditions.
This is a particularly cool one. Neuroscientists used to believe the brain was the only organ incapable of growing new cells—which partly makes sense, since we need our brains to be relatively stable over time, to keep our memories intact and to keep us us. But in recent years, it’s become clear that the brain, too, can grow new neurons, in a process called neurogenesis. And what seems to spur the growth of new neurons, perhaps above other activities, is aerobic exercise. (Other things, like meditation and antidepressant medication, have also been shown to trigger brain new cell growth.) The area of the brain that seems most capable of growing new cells is the hippocampus, the seat of learning and memory. It's also the area that’s known to “shrink” in depression, and particularly in dementia—so the fact that we may have some control over its health is exciting.
When it comes to these pushups, make sure your left and right hands are shoulder-width apart to keep proper form. Keep your left elbow and right elbow in as well so you can activate not only your triceps but also your chest. This exercise is great because it helps you protect your rotator cuff, which is upon your shoulders. Shoot for 15 to 20 reps in this 30-second set. Don't go for high speed, go for perfect form.
Though some people actually love physical activity and look forward to it, for many of us, exercising is a mighty drag. Exercise has also had an added PR problem in recent years: A growing body of evidence has shown that it’s not all that good for weight loss, which was probably many people’s reason for doing it in the first place. It may help with weight a little, especially for maintenance, but by and large, if you want to drop pounds, the most effective way is to eat less, not necessarily to exercise more. That said, research in recent years has also illustrated quite persuasively what exercise is good for—and it is actually good for a number of things, including some very profound things, like reducing dementia risk. Here’s what science tells us we should probably keep exercising for, even though we may not love every minute of it.
Not feeling up to heavy lifting? Try doing more reps at a lower weight instead and you’ll be kissing that arm fat goodbye in no time. Researchers at Canada’s McMaster University studied a group of 20-something men over a 12-week period, with half the study subjects lifting heavy weight and doing low reps, and another group lifting lighter weights for higher reps. The Journal of Applied Physiology study found that both groups increased their strength and muscle size by approximately the same amount, so if you’re relatively new to lifting or don’t feel up to hitting the heavy weights just yet, don’t worry; lighter lifts will still help you ditch the fat while gaining muscle tone.
