Though there are many ways in which you can improve the appearance of your arms, we need to let you in on a little secret — arm fat is totally normal — especially with regards to women! The reason for this is quite natural, as women have higher levels of estrogen, which means there is a physiological need for some extra fat to remain healthy (actually, a whole 6-11% more fat than men). This fat is particularly useful for women who are expecting, as it ensures that the baby has enough reserves to sustain itself.
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.
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.

Ah, arm fat. You know what it is. And let’s be honest. We all know we shouldn’t make a big deal of such things (all body types are beautiful, after all). But there is still a moment’s hesitation we all face when it comes to donning a cute spaghetti top or sleeveless dress. If there’s one word to describe arm fat, it would have to be stubborn. And no matter how much you control your diet or cut back on dessert, arm fat still seems to stay. Irritating, right? But before figuring out a way to reduce flabby arms muscles, it’s important to know what leads to the accumulation of arm fat.
Whether it’s a pick-up game of soccer, a group class at the gym, or just a run with a friend, exercise rarely happens in a bubble. And that’s good news for all of us. Studies show that most people perform better on aerobic tests when paired up with a workout buddy Aerobic exercise is promoted when individual performance affects the group: a test of the Kohler motivation gain effect.

You’ve recently tried on a strapless dress and noticed that your arms are looking soft and flabby. Having excess fat on your arms can cause self-consciousness about showing off your upper body. You aren’t doomed to a lifetime of long-sleeved shirts. It is not possible to target one area of your body for fat loss, but decreasing your total body fat percentage will give your arms a slimmer appearance. You can quickly trim inches off your arms with diet and exercise.

McAlpine's favorite on-the-go exercise is a classic for a reason: Push-ups are one of the most effective bodyweight exercises around. "Primarily, this move will target your chest, triceps, and your anterior deltoid muscles (the front of your shoulders)," says McAlpine. It also seriously works your core. Plus, there's something that just feels badass about working on push-ups and seeing yourself improve over time. "I personally love that feeling of strength that comes from this simple move," says McAlpine.
Exercise acts as a temporary diversion to daily stresses and it improves self-esteem. Increased core temperature during exercise may lead to reduced muscle tension and favourable alterations in brain neurotransmitters. Mood improvements may also occur due to the increased secretion of endogenous (internal) opiates, e.g. endorphins. Psychological changes may occur because of changes in norepinephrine, dopamine and serotonin, all hormones which can affect mood and anxiety levels.
Everyone's genetics are different. Your friend may hold more body fat in their glutes and thighs, while you may hold extra body fat in your arms or in your hips. We're all different. We're all unique little snowflakes and we hold our body fat in different areas. But, no matter who you are, if you get a low enough body fat composition, we guarantee you that you're going to lose body fat everywhere including your arms.

HOW TO DO IT: Start in a high plank. Push your hips back without arching your lower back until your knees flex to about 90 degrees. Pause for a beat, then explosively extend through your knees, ankles and hips while also pulling with your upper back as you lower into the bottom of a push-up. Keep your elbows tucked into your sides to protect your shoulders. Skip the push-up and just maintain a hold if you need it to be easier.
