Hey so I have recently lost over 30 pounds and am 5'5 and around 135 lbs, i wear a size four, but my arms are still huge. I have always had big arms, and my mother and grandmother do as well, but is their any special exercises that will trim down my arms rather than build muscle, because in the past whenever I have worked out my arms they have gotten bigger rather than smaller. Any suggestions would help because I really want to feel comfortable in sleeveless tops in the coming months.
If they are fat, there may not be much you can do about it, other than losing fat in general, since your genetics determines the pattern of how you gain or lose fat (exercising a specific area to spot reduce is ineffective).
If they are muscular, avoiding exercising your arms will reduce the muscle. But why would you want to do that? Although if your upper body exercise overemphasizes arms, you may want to shift the emphasis to your larger muscles like chest (e.g. pushups, dips, bench press) and back (e.g. pullups, rows) to get greater usable strength and muscle growth to help burn fat even at rest.
If your mom and grandma have larger arms, and you've been working out-it sounds like you are at a very good weight for your height-then it may just be genetic and not much you can do about it.
Maybe work on your shoulders rather than your arms. The toned and muscular shoulders will offset the arms and make them look smaller. You cannot help but work arm muscles while you're doing shoulders, but you're not focusing mainly on the arms.
If it's fat that is left on your arms, cardio cardio cardio! Unfortunately we cannot choose where the fat will leave us from, but all over cardio will burn the fat that's still on us!
