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.
You've cut your cancer risk. In a study of more than 14,800 women, those who had the highest levels of aerobic fitness were 55 percent less likely to die from breast cancer than those who were sedentary. Women considered moderately fit had about a 33 percent lower risk of developing the disease. Exercise may also help protect against endometrial, lung, and ovarian cancer, researchers say.
Last but not least for how to lose arm fat: Stand with your feet together and a dumbbell in each hand, palms facing inwards towards your body. With a slow and controlled motion, raise your arm out from your sides until they’re parallel with the floor. As you exhale, slowly lower your hands back to your sides. You should be able to see your hand in your peripheral vision, says Lagree: Your arm isn’t directly out to the side, but slightly forward. Lagree recommends doing two sets of 10-12 reps on each side. Next, find out the 14 things that happen to your body when you begin a strength training workout.
Stand with your feet hip-width apart and your arms at your sides. Bend your left knee, lifting your foot behind you. Squat down and raise your right arm out to the side to shoulder height, then reach your left hand down across your body, touching the floor outside your right toes (A). Stand up as you lift your left hand toward the ceiling, lower your right arm to your side, and raise your left thigh to hip level in front of you (B). Lower your left leg and repeat on the other side. That's one rep. Do 12 to 15 for a set. Do three sets, resting for 30 seconds between sets.
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.
