If you could magically go back in time to when you were young and fit and then photograph yourself every month up until present time, you would see a progression of how and where you gained weight (and fat). Maybe your legs started to show first and then your hips and then your waist and then your arms and finally your face showed the weight increase.
And you don’t need to sweat buckets to see the benefits of exercise, either. According to the physical activity guidelines from the Centers for Disease Control and Prevention (CDC), 150 minutes of moderate-intensity exercise with two days of strength training per week yields the same health benefits as 75 minutes of high-intensity exercise with two days of strength training each week — as does a combination of moderate- and high-intensity exercise, plus two strength training workouts.
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.
As people enter their forties and fifties, muscle mass starts to decline because of aging and, in some cases, decreased activity levels. Muscular atrophy can also occur because of health conditions, such as joint pain. As we age, it’s important to increase or maintain muscle mass through strength training, not only because it helps burn calories, but also because muscle mass is essential for strength and balance.
Complete sit-up pullovers. Sit-up pullovers will work your triceps and abs and help you burn fat. Hold a weight in each hand and lie on an exercise mat with your arms extended directly above you. With your knees bent and your feet flat, slowly curl your body up to lift your head, shoulders, and back off the ground. Keep your arms up and move them in a smooth arc-like motion towards your knees. Hold this position for one second, then lower yourself back down. Do 2-3 sets of 10-15 reps.
Feeling uninspired in the cubicle? The solution might be just a short walk or jog away. Research shows that workers who take time for exercise on a regular basis are more productive and have more energy than their more sedentary peers Employee self-rated productivity and objective organizational production levels: effects of worksite health interventions involving reduced work hours and physical exercise. Von Thiele Schwarz, U, Hasson, H. Department of Psychology, Stockholm University, Stockholm, Sweden. Journal of Occupational and Environmental Medicine, 2011 Aug;53(8):838-44. A randomized controlled trial of the effect of aerobic exercise training on feelings of energy and fatigue in sedentary young adults with persistent fatigue. Puetz, T.W. Flowers, S.S., O’Connor, P.J. Department of Kinesiology, University of Georgia, Athens, GA. Psychotherapy and Psychosomatics, 2008;77(3):167-74. Epub 2008 Feb 14.. While busy schedules can make it tough to squeeze in a gym session in the middle of the day, some experts believe that midday is the ideal time for a workout due to the body’s circadian rhythms.
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.
