Exercise improves self-confidence. One of the reasons many individuals do not attempt an exercise program is because they feel they are not very athletic or coordinated. Once an exercise program is begun, however, these same individuals discover that they are indeed able to work out successfully: gaining muscle tone and strength, improving their stamina, and improving how they feel emotionally. These revelations are very empowering. It is this increased sense of self confidence and improved sense of well-being that eventually becomes the sustaining force that helps people to continue their exercise program.
One doesn't automatically associate regular exercise with a reduction in the number of colds people get. But researchers from the University of Carolina found that people who exercised regularly were 23% less likely to get colds than those who exercised less. And if those who exercised got colds, the symptoms disappeared more quickly than in the study participants who did little exercise.
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.)

Get in plank position with your hands wider than shoulder-width apart (A). Lower your chest as close to the floor as you can. Holding that position, lift your right knee to the outside of your right elbow (B). Return to plank position, then push back up to start; repeat on the other side. That's one rep. Do three sets of 12 to 15 reps, resting for 30 seconds between sets.
Do 75-150 minutes of aerobic exercise a week. A slow metabolism and lack of cardiovascular exercise can lead to weight gain, and this gets worse as you age. Fight unwanted flab by doing at least 75 minutes of vigorous aerobic exercise each week to rev up your body and burn calories. Activities like bike riding, walking, swimming, skiing, jogging, and rollerblading are all good options.
Scientists don’t know exactly why exercise changes the structure and function of the brain, but it’s an area of active research. So far, they’ve found that exercise improves blood flow to the brain, feeding the growth of new blood vessels and even new brain cells, thanks to the protein BDNF (brain-derived neurotrophic factor). BDNF triggers the growth of new neurons and helps repair and protect brain cells from degeneration. It may also help people focus, according to recent research.
Those buff lab rats might be smarter than we think. Various studies on mice and men have shown that cardiovascular exercise can create new brain cells (aka neurogenesis) and improve overall brain performance Aerobic exercise is the critical variable in an enriched environment that increases hippocampal neurogenesis and water maze learning in male C57BL/6J mice. Mustroph ML, Chen S, Desai SC, Cay EB, DeYoung EK, Rhodes JS. Neuroscience Program, The Beckman Institute for Advanced Science and Technology, University of Illinois at Urbana-Champaign, Urbana, IL, USA. Neuroscience. 2012 September 6;219:62-71. Aerobic exercise improves hippocampal function and increases BDNF in the serum of young adult males. Griffin EW, Mullally S, Foley C, Warmington SA, O’Mara SM, Kelly AM. Department of Physiology, School of Medicine, University of Dublin, Trinity College, Dublin, Ireland. Physiology & Behavior. 2011 October 24;104(5):934-41.. Ready to apply for a Nobel Prize? Studies suggest that a tough workout increases levels of a brain-derived protein (known as BDNF) in the body, believed to help with decision making, higher thinking, and learning. Smarty (spandex) pants, indeed.
Studies have consistently shown that physical activity can help treat depression, and on the flipside, that low activity levels are a big risk factor for it. The antidepressant effect of exercise seems to be moderated in part through serotonin, the brain chemical that’s targeted with some antidepressants, and in part through bone-derived neurotrophic factor (BDNF). And this goes back to the generation of new cells mentioned earlier—exercise, though various mechanisms, seems to make the brain more plastic and more capable of growing new cells.
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.
If you want to lose weight and keep it off, you know that exercise should be an essential part of your routine. But the benefits of physical activity go far beyond just physical fitness. Increasingly, more and more research is showing that working out regularly can boost other aspects of your health as well, including cognitive function and emotional well-being.
If you have stubborn arm fat that won't go away with diet and exercise, there is an FDA-approved medical treatment that can help. UltraShape is pain free and you can even get the procedure done on your lunch hour. Not everyone is a candidate for the procedure, but you might be. Find a board-certified plastic surgeon in your area to discuss your budget and your options.

Begin in a forearm plank position. Press the right hand into the floor and then the left hand, rising to a high-plank position. Rotate your body to the right and extend the left arm toward the sky for a side-plank variation, allowing the left leg to scissor over the top of the right, with the inner edge of the left foot and the outer edge of the right foot touching the floor. Return to plank position. Release the right forearm back down to the floor and then the left forearm to return to the starting position. Repeat the sequence, this time starting with the left hand and coming to a left side-plank position. Continue the movement pattern without pausing, alternating sides. Complete a total of 10 to 12 reps (five to six reps per side).
McAlpine's favorite on-the-go exercise is a classic for a reason: Push-ups are one of the most effective bodyweight exercises around. "Primarily, this move will target your chest, triceps, and your anterior deltoid muscles (the front of your shoulders)," says McAlpine. It also seriously works your core. Plus, there's something that just feels badass about working on push-ups and seeing yourself improve over time. "I personally love that feeling of strength that comes from this simple move," says McAlpine.
