You'll also build muscle to fill out your arms and firm them up. “Generally, when people are complaining about underarm jiggle, they’re usually referring to the area that is governed by the tricep,” says Williams. “If the jiggle or looseness in that part of your arm is due to a lack of muscle, then strengthening and building muscle in your tricep will also create some change in the aesthetic of that area.” She recommends performing triceps push-ups, extensions, and dips to hone in on that area and add some muscular definition to your arms.
The biggest issue most people face in terms of the appearance of their arms isn’t a lack of muscle definition, it’s excess fat, meaning that what you’re eating is as crucial for fixing the problem as the amount you’re exercising. Instead of grabbing an electrolyte drink after your workout, try adding some grapefruit juice to your routine; researchers at Vanderbilt University found that obese study subjects who sipped a half-cup serving of grapefruit juice before meals significantly reduced their weight and BMI when compared to those who drank water instead. Fortunately, when you lose fat, it disappears all over your body, so a few sips of real grapefruit juice —the fresh, no sugar added stuff— can help you ditch those batwings for good.

Now that you know spot-reducing doesn’t work, let’s talk about what does. Like we said earlier, body fat is distributed in many places on your body and you lose body fat gradually all over as you make good choices to eat clean and exercise using both cardio and strength training. REMEMBER, you can change the shape of your arms as you lose the fat and work on arm strength exercises designed to tone and shape your biceps, triceps and shoulders. When all of these things are happening the sloppy, saggy fat begins to be replaced with toned, shapely arms. Let’s get down to the details you need to make this happen!

In a high plank position—palms flat on the floor beneath your shoulders, arms straight. Ease down on to your left forearm. Then, ease down your right arm until you’re in a forearm plank. Now push up with your right hand and then your left to return to a high plank. Repeat, alternating which side you lower first with each rep.” Lagree recommends doing two sets of ten reps. Another workout worth trying: these 9 resistance band exercises that will work your entire body.


The workout below, created by Jess Sims, NASM-certified personal trainer and instructor at Classpass Live, Shadowbox, and Fhitting Room in New York City, challenges your entire body and doesn't require a single piece of equipment. "It’s a full-body, dynamic workout that includes strength, power, mobility, and cardio," Sims says. "It’s also great because it’s customizable—if you have less than 20 minutes, you can do the circuit one time, or if you have more than 20 minutes you can do it three times."
To do tricep push ups, place your hands underneath your shoulders on an exercise mat. Make sure your fingers are spread wide and weight is distributed evenly between the 2 hands. Squeeze your abdominal muscles and straighten your legs behind you, coming up on the balls of your feet. Activate your leg muscles and push out from your heels. Your body should feel well supported and your lower back should be straight, not dipping or swaying from side to side.
If you are trying to lose flabby arms, it would help to include more protein in your diet. Protein rich food will help you build more muscle and help boost your metabolism, thus helping you burn more calories. Another reason to include more protein in your diet is that it will help you feel full for a longer time, making it easier to not cave into hunger pangs between meals. Remember, the aim is to just up the intake of protein, not limiting your entire diet to just protein. Include more of lean meats, beans, nuts, seeds, seafood and leafy vegetables to lose flabby arms.
