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.

Hello i’m 17 years old and i am currently 70 kg ! and i would like to reduce the fat on my arms and legs because i am very insecure about them, i’ve started drinking 4 bottles of water a day, i don’t eat sugar and i started eating less than before but my weight is not moving any lower i was wondering how long do i need to these exercises and how many !!!

In a nutshell, spot reducing doesn’t work. So before it gets you down, just know that this is not a realistic approach for anyone. Spot reduction is a  big misconception that still incorrectly holds precedence out there in the world of fitness, but here at 8fit we’re all about the science, and science tells us loud and clear that you can’t pick a spot on your body and work the fat away. The reason for this is that fat cells are stored all over the body, and where it seems like the fat cells gather/congregate is often due to genetics.

FIT TIP: To trim your tummy, do fewer crunches and more planks: Begin on all fours, hands under shoulders, knees under hips, then lower forearms to floor and extend legs straight behind you, balancing on toes. Keeping abs engaged and back flat, hold for 30 seconds; do 10 reps three or four times a week. Limit crunches to no more than three sets of 15 at a time. Anything beyond that isn't doing you much good, experts say.
After ingestion, carbs are converted into glucose and burned for fuel or stored as glycogen in the liver and muscles for later use. According to the European Journal of Applied Physiology, each gram of glycogen stored in the muscles holds at least 3 grams of water. The more carbs you eat, the more water you'll hold, which can make your arms look fuller.
For urban runners and power-walkers, one of the biggest obstacles is other people. It’s difficult to get in your meditative zone and enjoy your music when you constantly have to dodge people. To resolve this vexing issue, Runbell, a startup in Tokyo, has developed the runner’s version of the bicycle bell. With this lightweight brass bell warning people you’re approaching from behind, you’re free to maintain your transcendental state while continuing your workout. Head to their Kickstarter campaign to pledge your support.
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.
I started the sleek arm challenge and super excited. I’ve injured my knee badly and it can’t take any weight at the moment sooo I figured it’s time to build some strength in my arms and shoulders. I noticed a lot of comments regarding arm fat, I have excess fat on my arms so I’ll post at the end of the month and tell you guys if there was any changes. I’m doing the exercises in the morning and evening (day 2 of the challenge and it really does take just a couple of minutes each time, 3 sets each time since I can’t do any other form of exercise at the moment). I definitely feel something in my shoulder blades and my shoulders/back feel more open as opposed to hunched (Yaaay :) )

Scientists don’t know exactly why exercise changes the structure and function of the brain, but it’s an area of active research. So far, they’ve found that exercise improves blood flow to the brain, feeding the growth of new blood vessels and even new brain cells, thanks to the protein BDNF (brain-derived neurotrophic factor). BDNF triggers the growth of new neurons and helps repair and protect brain cells from degeneration. It may also help people focus, according to recent research.


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.”
It strengthens the brain. Studies have found that working out can lessen the severity of memory problems in older adults, and even decrease the risk of diseases like Alzheimer's. It can also have a positive benefit on the brain function of younger people. Research out of New Zealand shows that exercise improves executive function -- the general brain processes that include planning, memory, reasoning, problem-solving and more.
HOW TO DO IT: Stand with your feet together and hold both arms straight in front of you, palms together. Jump your feet apart, push your hips back, bend your knees and lower into a squat while pulling your arms apart and squeezing your shoulder blades together. Shift your weight over your right leg, and then your left leg, then right and left again before returning back to center and standing back up. Gradually increase your speed and range of motion throughout the set.
