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.

What you can do is remove body fat from your entire body. Basically, you have to decrease your overall body fat composition if you want to lose weight from any specific place on your body. When you do that, you are going to eventually target the part of your body you want and you're going to lose body fat there. You can't just do 1000 push-ups every day and lose arm fat. Instead, you have to lose body fat in your entire body while building those arm muscles. You build up those muscles so that when your body fat percentage is low enough, they can show through.
This is a time tested exercise to reduce arm fat and have toned arms. It is also an effective exercise to remove belly fat which strengthens the core. For this exercise, you need to select an item from your home to use as a weight. You can use a 2 liter cold drink bottle or a water bottle for this exercise. If you have a pair of dumbbells at home it works out just fine. The aim is to reach out for something which weighs around one kilo. Avoid using something breakable or valuable. It may fall down and break, so be very careful with your choice.
HOW TO DO IT: Assume a seated position with your palms loaded, hands underneath your shoulders and knees bent at 90-degrees with your feet underneath your hips. Raise your hips so your butt hovers above the ground, and then move your right hand and left foot forward. Continue this opposite-hand, opposite-food pattern as you crawl for 30 to 60 seconds. You can add difficulty by traveling backwards or side-to-side.
Visit your doctor. Certain medical issues may be contributing to the buildup of fat in your arms and the rest of your body, including a thyroid problem or diabetes. Your doctor can also test your hormone levels with a simple blood test to see if there is an imbalance. Low testosterone can contribute to weight gain in your arms, thighs, and lower abdomen.[10]
Are you constantly misplacing your keys or struggling to recall names? Exercising regularly can help jog your memory. A 2014 study found that aerobic exercise, like running or swimming, boosts the size of the hippocampus, the part of the brain responsible for memory and learning, in women with a recognized risk factor for dementia. (9) Besides looking to brain food to boost your memory and mental skills, start breaking a sweat!
Stand in a side lunge position with one leg bent parallel to the floor and the other leg straight to the side. Jump up explosively as you switch legs. Now the previously straight leg will be bent and the previously bent leg will be straight to the other side. Try and keep your core tight and stay as low as possible as you switch sides as fast as you can.
Bend your knees to lower down into a split squat. Your left knee should ideally form a 90-degree angle so that your thigh is parallel to the ground, and your right knee is hovering above the floor. (Quick position check: your left foot should be stepped out far enough that you can do this without letting your left knee go past your left toes—if you can't, hop your left foot out a bit farther away from the bench.)
Essentially, circuit weight training, or circuit bodyweight training, burns more calories than interval training, and that in turn burns WAY more calories than steady cardio. When you strength train, you burn calories. Then, your body needs to spend hours and hours afterwards rebuilding your muscles, which in turns burns even more calories (they call this the ‘afterburn effect).

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.
