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.
The biggest issue most people face in terms of the appearance of their arms isn’t a lack of muscle definition, it’s excess fat, meaning that what you’re eating is as crucial for fixing the problem as the amount you’re exercising. Instead of grabbing an electrolyte drink after your workout, try adding some grapefruit juice to your routine; researchers at Vanderbilt University found that obese study subjects who sipped a half-cup serving of grapefruit juice before meals significantly reduced their weight and BMI when compared to those who drank water instead. Fortunately, when you lose fat, it disappears all over your body, so a few sips of real grapefruit juice —the fresh, no sugar added stuff— can help you ditch those batwings for good.
Exercise can have a number of emotional benefits. Stress can be caused by elevated levels of the hormones cortisol, adrenaline, and norepinephrine. Exercise lowers these hormones, and increases serotonin, otherwise known as the happy hormone, which helps reduce stress. Working out can help keep depression and anxiety at bay. Plus, coping with mood disorders that are often associated with stress can be a little bit easier when you are in good physical shape.

While many arms exercises are biceps-focused, this simple isolation exercise dials in on the triceps, or the backs of your arms. (If you do find your biceps working overtime, this is a great way to make sure you're building balanced upper-body strength.) "By hugging your elbows in toward your body and using your own bodyweight, this area is majorly targeted," says Speir. And it's really easy to do anywhere. "The great thing about this move is it takes up the smallest amount of space," she adds.
Get out of the medicine cabinet and reduce your risk of heart disease the natural way. A meta-review of a variety of studies and trials conducted by researchers in 2013 — encompassing 305 trials with more than 339,000 participants — found that no statistically detectable differences existed between those who exercised and those who were given medications in the prevention of coronary heart disease and prediabetes.

With that said, don’t relax too much, or it loses the effect. It’s okay to indulge every so often. Treat yourself to some junk food you’re craving, imbibe a drink here and there, and spend a day vegging out on your couch. Staying healthy doesn’t have to be torture. Just turn down when you can and dedicate some time to better the health of your body. You only get one.
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.
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.
Endorphins, amiright? The link between exercise and happiness has been well-studied, and the results are very positive (just like you’ll be after some gym time). One study from the University of Vermont found that just 20 minutes of exercise can boost your mood for 12 hours. Cardio and strength training can both give you a lift, and 30-60 minutes of exercise three to five days a week is optimal for mood benefits, according to the U.S. Office of Disease Prevention and Health Promotion.
