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.
This is a particularly cool one. Neuroscientists used to believe the brain was the only organ incapable of growing new cells—which partly makes sense, since we need our brains to be relatively stable over time, to keep our memories intact and to keep us us. But in recent years, it’s become clear that the brain, too, can grow new neurons, in a process called neurogenesis. And what seems to spur the growth of new neurons, perhaps above other activities, is aerobic exercise. (Other things, like meditation and antidepressant medication, have also been shown to trigger brain new cell growth.) The area of the brain that seems most capable of growing new cells is the hippocampus, the seat of learning and memory. It's also the area that’s known to “shrink” in depression, and particularly in dementia—so the fact that we may have some control over its health is exciting.
Flabby arms can ruin your confidence – and your looks. Some men and women are genetically predisposed to carry fat in this area. Luckily, there are ways to slim your arms and improve muscle tone without even leaving home. Just keep in mind that you can't spot reduce fat. You need to eat clean and work your whole body to get results. Certain exercises, especially those targeting the triceps, are particularly beneficial.
For those sticklers who object to this regimen as a violation of the no-equipment stipulation—what are you, trapped in a shipping container?—Okafor has a go-to airport circuit, too, no chair required: four rounds of 20 squats, 20 lunges (with each leg), and 30 bicycle crunches. Maybe you're thinking: the airport? But don't people give you weird looks? "Of course," Okafor says. "But they're usually out of shape." Spoken like a man who isn't one bit afraid to curl a chair with a towel.
Because exercise helps use up oxygen, it causes your body to burn stored fat and helps you maintain a normal weight. For instance, if you walk 4 miles a day four times a week, you can burn about 1,600 calories or nearly half a pound a week. If you don't change your diet at all and keep walking the same distance over six months, you'll lose 12 pounds. Walk the same distance for a year and you'll drop 24 pounds.
Well, good (bad?) news: People who have dedicated their professional lives to defying Newton's First Law (you know them as "personal trainers") don't often have the luxury of skipping a sweat session. Next time you find yourself in need of a workout but without any of the things you think you need to get one, we got them to share the best workouts and circuits and exercises you can do anyway—no gear required.
I just wanted to make sure I understood too, so for the first round and block, you do 90 seconds of the squats , then 90 seconds of the high knees and then 90 of the next exercise? Then move to block two and do 90 seconds of each of those and then 90 seconds each of block three? Then of course the 60,45,40. Or do you do all three exercises of block one in the 90 seconds?
Demoing the moves below are Cookie Janee, a background investigator and security forces specialist in the Air Force Reserve; Amanda Wheeler, a certified strength and conditioning specialist and co-founder of Formation Strength, an online women’s training group that serves the LGBTQ community and allies; and Crystal Williams, a group fitness instructor and trainer who teaches at residential and commercial gyms across New York City.

You've cut your cancer risk. In a study of more than 14,800 women, those who had the highest levels of aerobic fitness were 55 percent less likely to die from breast cancer than those who were sedentary. Women considered moderately fit had about a 33 percent lower risk of developing the disease. Exercise may also help protect against endometrial, lung, and ovarian cancer, researchers say.


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.
Reduce your consumption of carbs, sugars, and animal fats. Consuming foods high in carbs and sugars will cause your body to secrete insulin, which is a main fat storage hormone in your body. When your insulin levels drop, this allows your body to burn fat. Lower insulin levels also help your kidneys shed excess sodium and water, which will help you reduce any water weight you are carrying.[10]

Love 'em or hate 'em, you can't talk about ultra-effective no-equipment exercises without mentioning burpees (especially when there's a push-up incorporated). "The burpee with push-up is a full-body exercise that works your core, arms, quads, glutes, and hamstrings," explains Harbison. "[They also] rapidly increase your heart rate, especially if you add an explosive jump at the end of the movement." Strength, check. Cardio, check.
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.
