Many people have problems with fat arms and these exercises for flabby arms are more geared towards ladies who want to lose these fats rather than to build arm muscle mass. Hopefully, these exercises will help reduce the self-consciousness when ladies wear sleeveless tops or dresses. There's nothing difficult about these exercises, but if you do them regularly, they will help in taking off the excess fat from your arms.
Buy a light dumbbell. It doesn't have to be heavy, about 1kg will do. Once you have it, you can start with doing the following exercise. Stand alongside a chair and lean slightly forward. Hold the dumbbell in one hand, and grab hold of the chair with the other hand for support. Pull back the arm holding the dumbbell slightly so your upper arm is almost parallel to the ground, and the elbow points backwards. Without moving your upper arm, slowly move your lower arm (with the dumbbell) backwards until your arm is straightened and pointing to the back. Relax your lower arm so the dumbbell is lowered and repeat this exercise again. The upper arm never moves in this exercise. Do this about 30 times, then switch to the other arm.
If you have flabby forearms, try this exercise. Sit comfortably on a chair and lean slightly forward. On one hand, carry a light dumbbell and rest the forearm on your thigh, leaving the hand unsupported. Let the hand sag a little as the dumbbell's weight pulls it down, and then, without moving the forearm, lift the dumbbell up as much as the hand can arch. There should be no jerking movements. Let your hand slowly sag into the original position again and repeat this exercise. Do this about 40 times and switch to the other hand.
If you have a slightly heavier dumbbell, you can do a bicep curl. Stand with both feet on the ground and hold a dumbbell in each hand (or do it one at a time). Take a deep breath as you bring up a dumbbell, keeping your upper arms stationary. The elbow is the hinge for this exercise. When the dumbbell is as high as you can bring it, start to exhale as your slowly lower the weight. Do not fully straighten your arm when the dumbbell gets lowered; this is to maintain a degree of tension in your arm. Repeat this exercise 10 times, then switch to the other arm. Each arm will do this exercise 10 times before switching to the other, and this exercise should be done for 3 sets per arm. When you alternate your arms, the other arm has a chance to rest. Be careful not to choose too heavy a weight.
If you are in doubt whether you should be performing these exercises for flabby arms, it's good to seek the opinion of a doctor. When you first starting doing these exercises, you may find it tough, so go slow. As your body adjusts, you will find it easier to do them. A healthy diet is very important to go along with your exercises. For best results, you will need a good weight loss plan.
