HOW TO DO IT: Start in a high plank with your hands underneath your shoulders. Jump your feet outside your hands and drop into a deep squat position, pushing your knees out and keeping your feels flat on the floor while prying your chest open with your hands. Return to the starting position and repeat. For an added challenge, try moving both forward and backward.
Aerobic exercise revs up blood flow to the skin, delivering oxygen and nutrients that improve skin health and even help wounds heal faster. “That’s why when people have injuries, they should get moving as quickly as possible—not only to make sure the muscle doesn’t atrophy, but to make sure there’s good blood flow to the skin,” says Anthony Hackney, an exercise physiologist at the University of North Carolina at Chapel Hill. Train long enough, and you’ll add more blood vessels and tiny capillaries to the skin, too.
And perhaps one of the best new findings about exercise — especially if you, like many people, struggle to find the time to fit it into a busy day — is that all those benefits of physical activity can be had even if you only squeeze in a few minutes of exercise a day. While doctors used to think that we needed to engage in 30 to 60 minutes of exercise a day, new research is finding that we can see benefits with shorter bursts of physical activity. “As little as 15 minutes a day of high-intensity activity that leaves you breathless, like swimming, can kick start your metabolic rate and reduce body fat and increase muscle mass,” says Dr. Berger.
Stubborn arm fat can make it difficult to wear short-sleeved tops comfortably due to poor fit or poor self-image. Although you cannot spot-reduce fat from the body, you can lose arm fat by adopting a healthy lifestyle, committing to an exercise routine and eating a nutritious diet. Schedule cardio five times per week, and strength-training three times per week, to slim down your arms.
HOW TO DO IT: Assume a bent-knee push-up position with your hands underneath your shoulders and your knees bent at 90-degrees, feet underneath hips. Step your left hand and your right foot forward and continue to crawl forward so that your opposite hand and foot are moving together. Repeat for 30 to 60 seconds. Start with smaller, slower steps and gradually increase the speed and distance traveled per step over time.
Stand with your feet hip-width apart and your arms at your sides. Lunge forward with your left leg so your right knee is nearly touching the floor and your left thigh is parallel to the floor. Bending forward, try to touch the floor on either side of your left foot (A). Push off your left foot; using that momentum, shift your weight to your right foot and swing your left leg behind you. As you sink backward into a lunge, rotate your torso 45 degrees to the right (B). Return to standing. That's one rep. Do 12 to 15 and repeat on the other side. That's one set. Do three, resting for 30 seconds between sets.
Exercise increases energy and vitality feelings. Sedentary individuals often complain of being too tired to work out. Ironically, exercise improves people's capacity for work so that people who exercise on a regular basis actually have more energy and greater strength and endurance for daily activities than do their sedentary peers. The feeling of increased energy, and vitality is one of the first things people tend to notice a few weeks after beginning to working out on a regular basis.
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.
Reduce your consumption of carbs, sugars, and animal fats. Consuming foods high in carbs and sugars will cause your body to secrete insulin, which is a main fat storage hormone in your body. When your insulin levels drop, this allows your body to burn fat. Lower insulin levels also help your kidneys shed excess sodium and water, which will help you reduce any water weight you are carrying.
Get down on all fours with your knees placed directly below your hips and palms placed directly below your shoulders. Now, raise your right arm forward and stretch your left leg backward at the same time. Create a tension in your back by flexing your foot. Hold the position for a few seconds and then come back to the starting position. Repeat the same using your left arm and right leg. Repeat 15 to 20 times on both sides.
The skin also serves as a release point for heat. (See “Why Does My Face Turn Red When I Exercise?” for more on that.) When you exercise, your muscles generate a lot of heat, which you have to give up to the environment so your body temperature doesn’t get too high, Hackney says. The heat in the muscle transfers to the blood, which shuttles it to the skin; it can then escape into the atmosphere.
A While using weights are one of the most effective ways of losing arm fat, it comes with the worry of whether your muscles would bulk up. While this is a common concern, building muscles doesn’t happen overnight and takes hours of intensive workout at a gym. If you, however, still concerned, you can lose flabby arms by opting for exercises that don’t include weights. Exercises such as pushups can help in this case, since you will use your own body weight to tone your arms. Tricep dips will also help you lose flabby arms without bulking up. Yoga is another great alternative.
3. It strengthens the lungs. Working hard increases lung capacity, and their efficiency in moving air in and out of the body. As a result, more oxygen is drawn into the body and more carbon dioxide and other waste gases are expelled. Regular exercise helps prevent the decline in oxygen intake that occurs naturally with age or as a result of inactivity.
Exercise has long been correlated with a longer life, but it’s only recently started to become clear why this might be. Studies, like a new one in the journal Preventive Medicine which found that exercise is linked to longer caps at the ends of chromosomes, have helped flesh this out a bit more. These caps, called telomeres, naturally shorten as we age, with each cell division. People who live a long time have telomeres that are in better shape than those who don’t—but there’s a lot we can do to affect the rate at which they shorten over the years. The team behind the new study looked at data from CDC's National Health and Nutrition Examination Survey, and found that for people who exercised regularly, their telomeres were 140 base pairs longer on average than sedentary people's. Which correlates to being years “younger” than their sedentary peers.
