Exercise stretches muscles and joints, which in turn can increase flexibility and help prevent injuries. Exercise may also improve balance by increasing strength of the tissues around joints and throughout the body, thus helping to prevent falls. Weight-bearing exercise, such as brisk walking and weight training, strengthens bones and helps prevent osteoporosis. Exercise often can improve function and reduce pain in people with osteoarthritis, although regimens must be developed specifically for each person, and exercises that put undue strain on joints, such as jumping and running, may need to be avoided.
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.

Think you can’t get a good workout while you’re sitting? Think again. In fact, the seated lat pulldown is one of the best exercises for toning those arms in a hurry. Using a pulldown machine, grip the bar and pull to chest level, and then raise again. This exercise makes it easy to build your biceps quickly and helps strengthen and tone your shoulders, which can make your arms look leaner, as well.
If it’s about the fat, then your goal should be to lose weight overall, rather than focus on specific areas. Your best bet is to start with your nutrition. Eating a healthy and balanced diet will maximize your chances for weight loss. If you’re using the 8fit meal plan, then getting the right amount of veggies and whole grains shouldn’t be too much of a problem.
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.

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.
