“Medicine ball slams are a dynamic, explosive, and highly metabolic exercise that does not simply target one muscle group,” explains Chris DiVecchio, trainer and founder of Premier Body & Mind. On the surface, the obliques, hamstrings, quads, biceps, and shoulders are the primary movers of this exercise. “But as time goes on and fatigue sets in, nearly every other muscle in the body, in one way or another, may become involved as a secondary mover which makes this a total gut blaster,” he adds. Doing side-to-side ball slams versus overhead slams incorporates more oblique ab work. 

Okay, you get the point: belly fat = bad. How do you lose it? You have to think beyond crunches and planks and adopt a well-rounded approach. “It’s got to be more losing fat as a whole,” agrees Chris Gagliardi, a certified personal trainer at the American Council on Exercise (ACE). Without further ado, here are the best ways to lose belly fat once and for all.
Even though artificially sweetened drinks are calorie-free, drinking too many can actually hinder your fat-loss progress. It seems that beverages like diet soda mess with your brain’s ability to regulate calorie intake, causing you to feel hungrier than normal so you eat more total calories. Other research suggests that the sweet taste of these drinks can increase the release of insulin, which can blunt fat-burning and enhance fat storage.
It's more challenging than a normal plank where your hands are on the floor, because the BOSU tests your balance, says Sanford. "When your body tries to find control as your balance is challenged, your abs, obliques, and deep transverse abdominal muscles are activated," he says. Strengthening these core muscles also helps increase your metabolism, ultimately helping you to burn more calories and fat.
Get active in small ways. Even the slightest amount of activity is better than none at all. Studies show that fidgeters, on average, weigh less. Non-fidgeters are even more likely to store calories as fat. So in addition to cleaning the house, walking the dog, and parking on the far side of the parking lot, find time to fidget, if that's your kind of thing![21]

Cut back on calories. The most important part of losing weight is not working out until you collapse — it's your diet. If you burn 500 to 750 more calories than what you eat every day, you will lose 1–2 pounds every week (any more than that is considered unsafe weight loss). There are tons of little changes you can make to cut calories from your diet, from replacing high-calorie dressings with vinaigrette and asking for all dressings/sauces served on the side, eating at the table instead of in front of the tv, skipping cheese and other fatty additions to your salads and meals, using smaller plates, leave off the whipped cream on your coffee drink, and on and on.[2]
2. Go to sleep earlier: A study in BMC Public Health found that people who racked up insufficient sleep on the reg were more likely to have a higher BMI. Meanwhile, researchers from the University of Chicago found that sleep loss causes decreased glucose tolerance and insulin sensitivity (those processes that cause your body to shuttle nutrients into fat cells instead of muscle cells) as well as elevated levels of ghrelin—the hunger hormone—and cortisol, the stress hormone that encourages your body to store fat. What’s more, the less you sleep, the less testosterone your body is able to produce. In short, skimping on sleep messes with all the hormones that help extra fat off your body—so hit the hay already. Shoot for at least 7 hours a night, more if you’re training hard because your body needs more time to repair and rest.

Find ways to reduce your stress. People under excess stress tend to make less healthy food choices, and they may also burn fat more slowly. Excessive stress is bad for your skin, it's bad for your sleep, it's bad for relationships — it's just bad overall. So find a healthy way to get rid of it! You'll feel better no matter how much it helps you in losing body fat.[19]
Walking puts all of the abdominal muscles to work. Make sure you swing your arms and contract your midsection while you walk, and maintain a brisk pace. Once you get your body accustomed to a daily walk, you'll hate to go a day without it. Walk for at least thirty minutes each time to achieve the aerobic effect, and be sure to drink plenty of water.
Body fat seems so easy to add and so hard to get rid of. You try to work out and restrict your calorie intake, and yet the fat still refuses to go away. If this sounds familiar, rest assured that there are healthy options for effectively burning fat. While there's no guarantee that your fat will simply melt away (as many fad diet/pill/exercise ads promise), you can improve your health and appearance by getting your body working for you — and against your excess fat.
Ansari says alcohol can prevent weight-loss in several ways, including the fact that heavy alcohol intake can stimulate food intake. "Binge drinking can overload the liver. The liver then prioritizes processing alcohol over other nutrients and then stores the protein, carbs, and fat as fat in the body," Ansari explains. The Centers for Disease Control and Prevention (CDC) defines binge drinking as having five or more drinks for men, and four or more drinks for women in two hours. "Also, alcoholic beverages are often mixed with sugar-rich beverages. Drinking more than moderate amounts of alcohol can cause calories to add up quickly."
