You're protecting yourself against colds, flu, you name it. Exercise elevates your level of immunoglobulins, which are proteins that help bolster your immune system and ward off infection. "Every sweat session you do can help strengthen your immune function for about 24 hours," says Cedric Bryant, PhD, chief science officer for the American Council on Exercise.
Some call it “flab”, others call it “sag”, or even “jiggle.” Whatever it is that you call the excess fat on your arms, know that you’re not alone. A lot of us have found ourselves in the dilemma, wondering how to lose arm fat and why it’s even there in the first place. Is it something I ate? Is it something I did or didn’t do? What shirt can I wear to hide to cover those parts?
Most people end a tough workout with a hot shower, but maybe we should be breaking out the colored pencils instead. A heart-pumping gym session can boost creativity for up to two hours afterwards Exercise enhances creativity independently of mood. Steinberg H, Sykes EA, Moss T, Lowery S, LeBoutillier N, Dewey A. The British Journal of Sports Medicine. 1997 September;31(3):240-245.. Supercharge post-workout inspiration by exercising outdoors and interacting with nature (see benefit #4) The cognitive benefits of interacting with nature. Berman, M.G., Jonides, J., Kaplan, S.

Next time you need a burst of creative thinking, hit the trails for a long walk or run to refresh the body and the brain at the same time.
HOW TO DO IT: Start in a bent-knee push-up position with your palms underneath your shoulders and knees bent at 90-degrees. Kick your right leg in front of you and assume a one-arm, one-leg hip bridge. Hold for one count, then reverse the movement and repeat on the other side. Move at a slower, more-controlled pace if it’s difficult, or even try a modified version called “sit-throughs,” where you sit on the outside of your hip as you move to each side.
As little as 30 minutes of cardio three to five days a week will add six years to your life, according to research at the Cooper Clinic in Dallas. Do that plus a couple of days of resistance training and you'll not only live longer but also look younger, feel happier, have more energy, and stay slim.

Quick Q&A: Which is better at relieving anxiety — a warm bubble bath or a 20-minute jog? You might be surprised at the answer. The warm and fuzzy chemicals that are released during and after exercise can help people with anxiety disorders calm down. Hopping on the track or treadmill for some moderate-to-high intensity aerobic exercise (intervals, anyone?) can reduce anxiety sensitivity Effects of aerobic exercise on anxiety sensitivity. Broman-Fulks JJ, Berman ME, Rabian BA, Webster MJ. Department of Psychology, The University of Southern Mississippi, Hattiesburg, MS, USA. Behavior Research and Therapy. 2004 February;42(2):125-36. Exercise for the treatment of depression and anxiety. Carek PJ, Laibstain SE, Carek SM. Department of Family Medicine, Medical University of South Carolina, Charleston, SC, USA. The International Journal of Psychiatry in Medicine. 2011;41(1):15-28.. And we thought intervals were just a good way to burn calories!
Emerging research suggests that it doesn’t take much movement to get the benefits. “We’ve been interested in the question of, How low can you go?” says Martin Gibala, an exercise physiologist at McMaster University in Ontario. He wanted to test how effective a 10-minute workout could be, compared to the typical 50-minute bout. The micro-workout he devised consists of three exhausting 20-second intervals of all-out, hard-as-you-can exercise, followed by brief recoveries. In a three-month study, he pitted the short workout against the standard one to see which was better. To his amazement, the workouts resulted in identical improvements in heart function and blood-sugar control, even though one workout was five times longer than the other. “If you’re willing and able to push hard, you can get away with surprisingly little exercise,” Gibala says. (For more on the 1-minute workout read this.)
And perhaps one of the best new findings about exercise — especially if you, like many people, struggle to find the time to fit it into a busy day — is that all those benefits of physical activity can be had even if you only squeeze in a few minutes of exercise a day. While doctors used to think that we needed to engage in 30 to 60 minutes of exercise a day, new research is finding that we can see benefits with shorter bursts of physical activity. “As little as 15 minutes a day of high-intensity activity that leaves you breathless, like swimming, can kick start your metabolic rate and reduce body fat and increase muscle mass,” says Dr. Berger.
Research has shown that to manage weight, you should exercise energetically for at least 30 minutes a day. You can also do an hour of intensive exercise every second day if this fits into your schedule more easily. Be consistent and be regular. Do those one-hour exercise sessions three to four times every week, not just one week a month, and you will achieve the result you desire - to lose weight and keep it off, says Dr Ingrid van Heerden, registered dietician.
The skin also serves as a release point for heat. (See “Why Does My Face Turn Red When I Exercise?” for more on that.) When you exercise, your muscles generate a lot of heat, which you have to give up to the environment so your body temperature doesn’t get too high, Hackney says. The heat in the muscle transfers to the blood, which shuttles it to the skin; it can then escape into the atmosphere.
