Working out your arms is an important part of any exercise routine. However, if you’ve noticed an uneven muscle tone or a difference in the strength of your arms, you may need to make a few changes to your routine. Fortunately, evening out your arms is as simple as correcting your form, focusing on your weaker arm when you exercise, and using your weaker arm to do daily activities. Implementing a balanced workout routine also helps you build up your arm muscles evenly.

Evening Out Arm Muscles

Exercise in front of a mirror to correct your form and ensure you’re working both arms evenly. Then, use dumbbells to complete a few more reps for your weaker arm than your stronger one. Using your weaker arm more in your daily life, like carrying groceries or making coffee, can help strengthen it, too.

Exercising with the Proper Form

  1. Sometimes, a muscle imbalance can be caused by exercising improperly. When you workout, try to do it in front of a mirror so you can see your arms, and check to see if you are working both in the same way. [1]
    • For example, when you do dumbbell curls, you could be leaning over too much on one side. This can create an imbalance in your muscle tone.
    • When you lift barbells, you could be lifting one side higher than the other. This could make one arm stronger.
    • If you are feeling pain or discomfort as you work out, it could be a sign that your form is off.
  2. When you use barbells or other equipment that works both of your arms at the same time, make sure you engage your weaker arm as much as you are engaging your stronger one. Really think about how your muscles feel and if you are spreading out the weight over both your arms. [2]
    • Being mindful while you exercise can also help you avoid potential injuries.

  3. When one arm is weaker than the other, your body could be compensating by twisting your core or shoulder when you do your reps. Focus on holding your body straight and not letting your torso twist or bend as you workout. [3]
    • For example, when you do shoulder presses with a dumbbell, make sure your posture remains upright.

    Tip: Having a friend or trainer watch you while you work out can help you spot movements like this.

  4. Talk to a professional about your uneven muscle tone and work with them to create an exercise program that’s right for you. You can usually find personal trainers at your local gym or fitness center.
    • Personal trainers are certified in physical training and exercise, so they know how to create safe, healthy workout plans that are right for you.

Creating a Balanced Workout Routine

  1. Sometimes, uneven muscle tone can be caused by flexibility issues. After you work out, do some basic arm stretches to cool down your muscles and improve your mobility. [4]
    • Pull one arm across your chest and hold it for about 30 seconds, then repeat that on the other side.
    • Try pushing your arm behind your head and holding it for 30 seconds, then repeat that on the other side.
  2. Instead of focusing on just your biceps, be sure to include your triceps and your shoulders as well. You can do tricep pushups, tricep dips, and shoulder presses to include these muscles in your workout. [5]
    • To do tricep pushups, get into a normal push up position but keep your arms close to your shoulders. Lower your body down while keeping your arms parallel to your torso.
    • To do tricep dips, get into a crab walk position with your hands behind you facing towards you and your torso facing upwards. Lift your rear off the ground and then bend your arms to do a reverse pushup motion.
    • To do a shoulder press, grab a barbell or 2 dumbbells. Stand with your legs shoulder-width apart and your back straight, and raise your weights directly above your head. Then, lower them down so the weights are next to your head.
  3. If you’ve found a workout routine that you love, it can be hard to switch it up. Try to incorporate different exercises into your routine so you can vary which muscles you are working out. [6]

    Tip: You can also try using different equipment, like a resistance band instead of barbells.

Strengthening Your Weaker Arm

  1. Often, your non-dominant arm is the one that’s weaker since you use it less. Try using your weaker arm to brush your teeth, eat food, make coffee, and do your daily activities to strengthen it incrementally. [9]

    Variation: If you are ambidextrous, meaning you don’t have a dominant hand, try using both of your hands evenly to do your daily tasks.

  2. Dumbbells help to focus the weight on one arm instead of spreading it out over both of your arms. Try using dumbbells as much as you can so you can really focus on strengthening your weaker side. [11]
    • You don’t have to give up barbells completely, but it is much easier to focus on one arm when that’s the only one you are working out.
    • For example, instead of doing bicep curls with a barbell, try doing them with a dumbbell instead.
  3. This will help you work out your weaker arm before you get tired. Try doing every exercise on your weaker arm first to really focus on building those muscles up. [12]
  4. To really bulk up your muscles, you can work out your weaker arm more than your stronger one. Try adding 4 to 5 more reps of each exercise to your weaker arm after you’re done. [13]
    • For example, if you did 10 bicep curls on each arm, do 5 extra on your weaker arm.
    • Use caution when you work out your weaker arm more, as you could actually make your weaker arm stronger than your other arm.
    • Try taking at least 6 weeks off your usual workout routine to correct your muscle imbalance. You'll need at least 6 weeks to see strength gains and muscle growth in your weaker arm. [14]
  5. If you’ve noticed your muscles look bigger in one arm, take a photo with a date and time stamp. Keep taking photos of your arms once a week to see how your muscles in the weaker side are developing.
    • It can be hard to track changes in yourself since you look at yourself every day. Taking pictures can help with that.

Common Questions: Fixing Uneven Arms

How long does it take to fix uneven arms?

It can take at least 6 weeks to balance out your arms. After 6 weeks, you might notice that your arms have a more similar muscle definition and your weaker arm is easier to work out.

What causes arm imbalance?

An arm muscle imbalance is typically caused by stressing the muscle on one side more than the other. This might be due to playing a sport with your dominant hand, using your dominant hand for daily activities, or exercising with an improper form. Poor posture can also lead to an imbalance. [15]

Are uneven arms normal?

It’s normal for one arm to be slightly stronger or bigger than the other. This is because most people have a dominant arm that they use more for daily activities and exercising.
