Regular exercise has several beneficial effects on your body that can improve the function of your musculoskeletal system, your cardiovascular system, your respiratory system, your metabolism, and even your brain. Engaging in regular exercise significantly reduces your odds of developing heart disease, diabetes, kidney disease, lung disease, and some kinds of cancer. People who exercise live longer, and (possibly more importantly), suffer fewer of the chronic illnesses and infirmities that often make old age difficult.
The body uses both carbohydrates and fats as energy sources. But after consistent aerobic exercise training, the body gets better at burning fat, which requires a lot of oxygen to convert it into energy. “One of the benefits of exercise training is that our cardiovascular system gets stronger and better at delivering oxygen, so we are able to metabolize more fat as an energy source,” Hackney says. As a result, your fat cells—which produce the substances responsible for chronic low-grade inflammation—shrink, and so does inflammation.
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.
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.
Today we're going to talk about how to get rid of arm fat by using a jump rope. We get lots of comments from people about how they want to get rid of their bat wings and lose some arm fat. Just like with belly fat and man boobs, you can't just pick areas of your body you want to trim down. To get those sexy, shredded arms, you've got to tackle fitness and nutrition meant for your entire body. Today, we're going to show you how proper nutrition and an intense workout can get you closer to the Jump Rope Dude lean, athletic physique.
The high-intensity part of this workout is known as HIIT or high-intensity interval training. We're going to be using a 1/2-pound energy rope by CrossRope, which you can get for 10% off if you click that link. This rope, along with the heavy rope and agility rope, are what we use in every one of our videos and exercises because it's the best we've found on the market. This rope is a little heavier so it takes your fat burning to the next level. If you have a different jump rope that's cool too, just use the one you have. But by using a heavier rope, you're adding more resistance so you're going to burn more calories in less time. That's specifically why we're using this rope because we want to be as efficient as possible when looking to burn calories and fat loss.
Sweating it out in the gym is a known de-stressor. Harvard Medical School has shown that aerobic exercise helps curb stress hormones like cortisol and adrenaline (as long as you're not overdoing it), while also flooding your system with feel-good endorphins. It also ups the calming, good-mood brain chemicals serotonin and dopamine. So while exercise itself is actually putting low-level physical stress on the body, it can be pretty mentally relaxing.
Previous studies from her lab have also shown that the exercise is linked to changes in the secretion of stress hormones like epinephrine (a.k.a. adrenaline) and norepinephrine. “Our work has shown that each moderate, relatively short exercise bout exerts regulatory/suppression effects over inflammatory activities of immune cells," says Hong, "and in order to maximize this ‘benefit,’ repeated and regular exercise is recommended. In fact, we have also found that higher physical fitness is associated with better regulation of inflammatory activities of immune cells through stress hormones even among obese individuals.”
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.”
The answer, then, is a short workout, right? Something that takes, say, 20 minutes tops. You’ll usually be able to squeeze that in between punching out at work and getting ready for your evening activities. But here’s the rub: It may only take you 20 minutes to train, but it takes 10-15 minutes (at least) to drive to the gym, five minutes or so to get in and out of the locker room, then 10-15 minutes to drive back home. You’re talking at least 45 minutes for the whole deal, but probably more like an hour-plus.
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.
