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.
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).
While some women worry about the size of their hips, belly or thighs, other women feel that they have fat arms. Do your arms look as tight and firm as you'd like them to? If they don't, you're not alone. Almost all women struggle with some degree of flabbiness in their upper body and some of us even spend hours at the gym trying to lose arm fat or flabbiness in the upper back. 
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.
Most gymgoers who are struggling with flabby arms either spend hours on the treadmill or work their biceps day in, day out. What you should focus on are the triceps because this muscle makes up two-thirds of your arm. Train it once or twice per week to lose arm fat and build upper-body strength. Your arms might get bigger, but they'll look leaner and more defined.
Research has shown that to manage weight, you should exercise energetically for at least 30 minutes a day. You can also do an hour of intensive exercise every second day if this fits into your schedule more easily. Be consistent and be regular. Do those one-hour exercise sessions three to four times every week, not just one week a month, and you will achieve the result you desire - to lose weight and keep it off, says Dr Ingrid van Heerden, registered dietician.
