That’s bad news, but emerging evidence shows that there are plenty of compelling reasons to start moving at any age and even if you’re ill or pregnant. Indeed, scientists are learning that exercise is, actually, medicine. “There is no pill that comes close to what exercise can do,” says Claude Bouchard, director of the human genomics laboratory at Pennington Biomedical Research Center in Louisiana. “And if there was one, it would be extremely expensive.”
3. It strengthens the lungs. Working hard increases lung capacity, and their efficiency in moving air in and out of the body. As a result, more oxygen is drawn into the body and more carbon dioxide and other waste gases are expelled. Regular exercise helps prevent the decline in oxygen intake that occurs naturally with age or as a result of inactivity.
When she's working out sans equipment, Marraccini's favorite exercises are all things core-related. "A strong core never goes out of style," says Marraccini. This makes sense, considering that having a strong and stable core is essential for both everyday movements as well as exercising. While regular crunches really only target the upper portion of your abdominals, runner's crunches work your entire core as you sit all the way up, including your obliques, lower back, hip flexor muscles, and rectus abdominis (which is what you probably think of when you think "six-pack" muscles).
While a Bulgarian split squat isn't technically a zero-equipment move, they can still be done pretty much anytime, anywhere. "It activates many muscle groups and can be performed with any lifted surface, like a couch, bench, small table, or even an airport chair," says DiDomenico. The move is a major lower-body burner—you'll feel it in your quads, glutes, inner thighs, hamstrings, and even your calves.
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.)
Commit to a 7-day meal plan. Create a 7-day meal plan that covers 3 main meals (breakfast, lunch, dinner), scheduled at the same time of day, and 2 small snacks (between breakfast and lunch, and lunch and dinner), scheduled at the same time of day. A set meal plan will ensure you eat at a consistent time every day and do not skip or miss a meal. Consuming about 1,400 calories a day, combined with exercise, can help you to achieve healthy weight loss.
To do tricep push ups, place your hands underneath your shoulders on an exercise mat. Make sure your fingers are spread wide and weight is distributed evenly between the 2 hands. Squeeze your abdominal muscles and straighten your legs behind you, coming up on the balls of your feet. Activate your leg muscles and push out from your heels. Your body should feel well supported and your lower back should be straight, not dipping or swaying from side to side.
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.
