Arm curls, also known as bicep curls, are one of the most basic and effective exercises for developing the biceps muscles. It is a great exercise for anyone looking to add size and strength to their arms. However, most people don’t perform arm curls correctly, which can result in injury or ineffective results.

In this article, we will guide you on how to perform arm curls like a pro, so you can maximize your gains, reduce your risk of injury and develop stronger and bigger biceps.

Benefits of Arm Curls

Performing arm curls comes with numerous benefits, including:

  • Helps in building bigger bicep muscles
  • Strengthens your arms and shoulders
  • Increases grip strength
  • Improves overall upper body strength

So, if you want bigger, stronger arms, arm curls should be part of your workout routine.

Preparation Tips

Before we dive into the steps of performing arm curls, let’s first highlight some preparation tips to ensure you’re doing it correctly.

Choose the Right Weight

Choosing the right weight can make or break your arm curls. You don’t want the weight to be too light that it doesn’t stimulate growth, but you also don’t want it to be too heavy that you can’t perform the exercise correctly.

Start with a weight that you can comfortably do 10-12 reps with. If you can do more than 12 reps with that weight, it’s too light. Likewise, if you can’t finish 8 reps with that weight, it’s too heavy.

Stand with Proper Form

Stand with your feet shoulder-width apart, your back straight, and your core engaged. Don’t hunch your back or arch it. Doing so can injure your back or put undue pressure on it whilst exercising. Keep your shoulders back and avoid swinging your arms.

Keep Your Wrist Straight

When performing an arm curl, ensure that your wrist is straight and not bent. A bent wrist can lead to wrist pain or strain.

Steps for Arm Curls

Now that you have adequately prepared, let’s dive into the steps of performing arm curls:

Step 1: Hold the Dumbbells

Stand straight while holding a dumbbell in each hand, with your palms facing forward. Your hands should be hanging at arm’s length on both sides of your body. Keep your elbows locked into your sides.

Step 2: Begin the Curl

Slowly raise one dumbbell towards your shoulder by bending your elbow, keeping your upper arm locked in place. Keep your wrist and elbow straight as the weight rise.

Step 3: Hold for a Second

Once the dumbbell reaches shoulder level, hold it for a second before lowering it back to the starting point.

Step 4: Repeat

Repeat for the other arm and alternate between arms until you’ve completed your desired reps.

Note: While performing an arm curl, keep your elbows close to your sides and avoid swinging your arms, as it can lead to injury or ineffective results.

Common Mistakes to Avoid

Without proper form and technique, you’ll likely experience injuries, or you won’t achieve the desired results. Below are some common mistakes you should avoid when performing arm curls:

Moving Your Elbows

If you notice your elbows moving while performing an arm curl, it means your weight is too heavy for you. Instead, reduce your weight and focus on your form and technique.

Swinging Your Arms

Swinging your arms during an arm curl can lead to back pain or an ineffective workout. To avoid swinging, keep your upper arm still and only move your forearm.

Speeding Up the Movement

Some people tend to rush through their movements, which can lead to injury or ineffective results. Slow, controlled movements are crucial when performing arm curls.

Tips to Make Arm Curls More Effective

If you want to make your arm curls more effective, consider the following tips:

Focus on Your Form

Improper form can lead to injuries, and in some cases, the muscles you want to develop won’t get worked. Focus on each repetition, making sure that your elbows are close to your sides and that you’re not swinging too much.

Vary Your Weight and Reps

To build bigger, stronger arms, you should be consistent in your routine yet be dynamic in your repetitions and weight. For instance, one day, you can focus on high-rep, low weight arm curls, and the next, you can do low-rep, heavier curls. This will help you develop strength and size.

Incorporate Other Exercises

While arm curls can help you develop bigger, stronger arms, incorporating other exercises can help you develop other muscles that complement your biceps. For instance, triceps pushdowns and overhead presses can help you develop bigger and stronger shoulders.


Arm curls are a fantastic workout for anyone looking to develop bigger and stronger biceps. By following our tips and techniques above, you can safely and effectively build a more significant, stronger arm. Remember always to start with less weight and focus on each repetition to achieve the desired results.
