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.

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.
Exercise improves physical health. Physically active individuals have a much better health outlook than their sedentary peers. Even modest regular physical activity has a positive influence on people's health and vitality. A minimum of 20 to 30 minutes of moderate activity a day most days of the week will benefit health and assist with weight loss. A formal workout is not necessary to have these benefits; a brisk walk will suffice (although a more vigorous workout will suffice that much more).

Millions of women struggle to lose fat from their arms these days. Are you in a war with your flabby arms too? Fat arms are caused by sedentary lifestyle, unhealthy food habits, the body’s metabolic rate, medical issues, or even your genes. To address this problem you have to work extra hard on your triceps and biceps and lose overall weight from your body to get the desired result.
