Due to the accumulation of excess fat in the arm area, arm fat is caused. The fat deposition is quite difficult to burn in the arms. So the gradual deposition of fat in the arms leads to flabby arms.
Another reason for arm fat is the growing age. Our body tends to store more fat and the lean muscles start to decrease after the 20s. So one of the main causes of flabby arms is that there are more fat accumulation than the lean muscles. Another reason for arm fat is decreased metabolism. With the growing age the metabolism rate decreases which means burning fewer calories. Ultimately this condition leads to arm fat.
