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.
These beneficial effects in turn decrease the risk of heart attack, stroke, and coronary artery disease. In addition, colon cancer and some forms of diabetes are less likely to occur in people who exercise regularly. In short, regular exercise is one of the best things that people can do to help prevent illness, maintain healthy body weight, preserve health and longevity, and enhance quality of life.
If you struggle with a touch of fatigue, exercise might be just what the doctor ordered. According to a study from the University of Georgia, the blood flow benefits from exercise help carry oxygen and nutrients to muscles, which helps them produce more energy. They found that even low-to-moderate intensity exercise for just 20 minutes a day, three days a week for six weeks can help with that can't-keep-my-eyes-open feeling.
Lie on your back with the left leg extended and the right knee bent. Place the right foot on the floor and extend the right arm toward ceiling. Perform a crunch-like movement to lift the upper body, transitioning into a seated position, and continue to reach the right arm up. Place the left hand on the floor next to the left hip and push through the left hand and the right foot to lift the hips off the floor. Extend through the hips, reaching back with the right arm to perform a slight backbend. Slowly lower back down to the starting position. Repeat five to six reps on the right side before switching to the left.
HOW TO DO IT: Step to your left and lower your body into a lateral lunge, placing both hands on the floor. Without moving your feet, lift your hands and hips and shift your weight over your right foot, so you end up in a right-side lunge. Alternate back and forth for 30 to 60 seconds. To really kick up the burn, turn this movement into a monkey shuffle by simultaneously loading your hands, lifting your hips and shuffling your feet side-to-side between right and left lunge positions.
The single arm lateral raise is a power packed arm toning exercise that helps to lose fat fast from the arms and cuts out the jiggle. This exercise is also effective in strengthening the core muscles. Begin in a push-up position with knees and hands placed directly under the shoulders, holding a 600 ml water bottle or any similar weight in the left hand.
Now that those muscles are uncovered and ready to work on, it’ll be easier for you to see your progress, as the muscles will start to show up through the thinner layer of body fat. Arms are made up of two different muscles — the biceps in the front, and the triceps at the back. The main one to target when toning arms up is the tricep, but working out the bicep at the same time will lend your arms a more balanced structure.
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.
To perform reverse curls you will need a barbell with weight, enough to provide a challenging workout but not so much that you can’t complete a third set. Hold the bar at your waist in an overhand grip with your feet about shoulder-width apart; this is your starting position. Then you simply perform your basic curl exercise, flexing your muscles to lift the bar to shoulder level and return to starting position.
When she's working out sans equipment, Marraccini's favorite exercises are all things core-related. "A strong core never goes out of style," says Marraccini. This makes sense, considering that having a strong and stable core is essential for both everyday movements as well as exercising. While regular crunches really only target the upper portion of your abdominals, runner's crunches work your entire core as you sit all the way up, including your obliques, lower back, hip flexor muscles, and rectus abdominis (which is what you probably think of when you think "six-pack" muscles).
When stress isn't just stress, exercise can work wonders, too. There's a host of research proving that people with anxiety and depression can find major help in working out. According to the Anxiety and Depression Association of America, regular exercise has been found to help with various anxiety disorders, including panic disorder and OCD. Celebrities, including Lena Dunham, have talked about about how a regular exercise program has helped with her anxiety.
That's why BuzzFeed Life asked NYC-based personal trainer Albert Matheny, C.S.C.S., founder of Soho Strength Lab, to design nine high-intensity bodyweight-only workouts that you can do anywhere. These workouts are made for the exerciser who wants to get fitter and healthier, and feel great. Each one focuses on one of three goals: cardiovascular fitness, power and strength, and endurance.
Those buff lab rats might be smarter than we think. Various studies on mice and men have shown that cardiovascular exercise can create new brain cells (aka neurogenesis) and improve overall brain performance Aerobic exercise is the critical variable in an enriched environment that increases hippocampal neurogenesis and water maze learning in male C57BL/6J mice.

Neuroscience Program, The Beckman Institute for Advanced Science and Technology, University of Illinois at Urbana-Champaign, Urbana, IL, USA. Neuroscience. 2012 September 6;219:62-71. Aerobic exercise improves hippocampal function and increases BDNF in the serum of young adult males. Griffin EW, Mullally S, Foley C, Warmington SA, O’Mara SM, Kelly AM.

Studies suggest that a tough workout increases levels of a brain-derived protein (known as BDNF) in the body, believed to help with decision making, higher thinking, and learning. Smarty (spandex) pants, indeed.
