In a widely-cited study published in February 2013 in the American Journal of Health Promotion, researchers at Oregon State University looked at more than 6,000 American adults and found that even small amounts of physical activity — like pacing while talking on the phone or doing some jumping jacks during commercials while watching TV, as long as these short bursts of exercise add up to 30 minutes a day — can be just as beneficial as longer workout sessions at the gym.
When many people decide to "get fit," they assume it involves rigorous activity. But you don't have to spend hours in a gym to be physically active. People can get in shape by performing everyday activities in the home. Every time you and your child throw a softball, swim a lap, climb a flight of stairs, walk to the store, or carry packages, your health and fitness levels are improving.
Even when you have the best intentions, sometimes, it can be really, really hard to drag yourself to the gym. Whether your bed or brunch plans are calling your name, sidestepping workout plans is all too easy when you’re feeling tired, stressed, and your willpower is running dangerously low. Finding the motivation to work out doesn’t have to be about getting stronger or leaner. Sometimes those are goals, and sometimes they aren't, and there are a 1,001 other amazing reasons to lace up your sneakers or unroll your yoga mat that have absolutely nothing to do with losing weight. Here are 11 of our favorites. 

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.
There are few experiences in life more pleasurable than turning up the music and drowning out the world around you. With so many podcasts and music apps available on your smartphone, you can easily find entertainment options perfectly suited to your personal tastes. Never worry what people may think of you when working out;instead, crank up the volume and get lost in your own world. You’ll be in shape before you know it.
It boosts immunity. Regular exercise can reduce your risk of certain serious health conditions, including heart disease, diabetes and some cancers. It can also decrease your chances of developing -- and getting stuck with -- more common illnesses, such as flus and colds. (According to one recent study, colds lasted 43 percent longer for people who exercised once a week or less.)

“Inactivity is associated with increased risk for a number of cancers, including colon and breast cancer,” McCleary says. “Exercise has been linked with a decreased risk of developing cancer, death from cancer, and recurrence of certain cancers.” The suggested mechanisms at play include exercise’s beneficial effects on the immune and surveillance systems that detect and kill cancer cells, improved cardio-respiratory status, improved hormonal profiles, weight maintenance, and other beneficial metabolic effects, he says.
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.
Start the clock, and immediately do 10 plank taps in perfect form. When you’re done with the plank taps, go straight into jumping jacks until the clock reads 1:00. Then move on to the next move, walkouts, and do 10 perfect reps of those. Jumping jacks again until the clock reads 2:00. When you get to single-leg deadlifts, do 10 of those perfectly — stay on the same standing leg throughout — and finish out the minute with jumping jacks until it’s time for the next move at minute 3. Finish the circuit with 10 perfect jumping lunges.

And research published in November 2017 in the journal NeuroImage showed that aerobic exercise may be helpful in improving memory function and maintaining brain health as we age. The study, led by researchers at Australia's National Institute of Complementary Medicine at Western Sydney University, looked at brain scans of 737 people ranging in ages from 26 to 76. The group included a mix of healthy adults, people with Alzheimer's and other cognitive impairments, and people with a clinical diagnosis of mental illness, including depression and schizophrenia. The researchers found that exercises, like riding a stationary bike, running on a treadmill, or walking, slowed down the deterioration of brain size and slowed the effect of age on brain health.

We've got some happy news that will rev up your workout routine: The moment you head out on your run, launch into your Spinning class, or start your Pilates session, the benefits of exercise kick in. "We see changes in the body within seconds," says FITNESS advisory board member Michele Olson, PhD, professor of exercise physiology at Auburn University at Montgomery in Alabama. Your heart rate increases, and blood is delivered to your muscles. You start burning calories for fuel. And you get an almost immediate mood boost.

Start the clock, and immediately do 10 pushups in perfect form. When you’re done with the pushups, go straight into jumping jacks until the clock reads 1:00. Then move on to the next move, spider lunges (total, not per side). Do 10 of those with good form, and then jumping jacks until the minute is up. Then move on to the next move — 10 perfect reps of the jumping lunges, and then do jumping jacks until the end of the minute. And finish up with 10 perfect walkouts.

1. It strengthens the heart. The heart is a muscle. Like other muscles, its performance improves when it's regularly challenged by exercise. The heart responds to exercise by becoming stronger and more efficient. Strengthening the heart muscle can help ward off heart disease -- the leading cause of death in the United States, according to the U.S. Department of Health and Human Services -- even in early childhood.
