Alternating vs. Bilateral Curls

Published by PowerQuad Fitness on June 21, 2023. 


Are you ready to elevate your weightlifting game and sculpt those massive biceps? If you've been hitting the gym, chances are you've come across the eternal debate: alternating curls versus bilateral curls. Don't worry because we're here to break it down for you to maximize your gains. Let's dive into the world of curl variations and discover which one is the ultimate weapon for building sleeve-busting arms.

Understanding the Alternating Curl Technique

When it comes to targeting those guns, alternating curls offer a unique twist to your arm training routine. By working one arm at a time, you not only engage the biceps but also challenge your core for stability and balance. This unilateral movement forces each arm to pull its own weight, resulting in increased muscle activation and coordination. To take your alternating curls to the next level, focus on tempo variations like slow negatives or explosive concentric phases to activate different muscle fibers.

Understanding the Bilateral Curl

Bilateral curls, on the other hand, involve lifting weights simultaneously with both arms. This technique allows for greater load capacity, which means you can pile on those plates and really push your limits. Bilateral curls recruit both biceps simultaneously, providing a balanced and symmetrical workout for your arms. By engaging both arms at once, you can build overall strength and power, ultimately leading to increased gains in mass and size.

Breaking Down the Benefits

Now that we've covered the basics of each technique, let's delve into the specific benefits they offer:

Alternating Curls:

  • Enhanced stability and balance through unilateral training.
  • Increased muscle activation and coordination.
  • Opportunities for tempo variations to target different muscle fibers.
  • Improved mind-muscle connection and focus.
Bilateral Curls:
  • Greater load capacity for heavier lifting.
  • Balanced and symmetrical development of both biceps.
  • Enhanced overall strength and power.
  • Potential for increased muscle mass and size

Finding Your Perfect Fit

Choosing between alternating and bilateral curls depends on your personal goals, preferences, and even your current fitness level. Here are a few factors to consider:

  1. Beginner or Advanced: If you're new to weightlifting, alternating curls may be a good starting point to build stability and coordination. Advanced lifters looking to increase strength and maximize load capacity may find bilateral curls more suitable.
  2. Muscle Imbalances: If you have noticeable muscle imbalances between your arms, alternating curls can help you address and correct these discrepancies over time. Bilateral curls, on the other hand, ensure both arms receive equal attention and work together harmoniously.
  3. Variety and Progression: To keep your workouts fresh and challenging, consider incorporating both alternating and bilateral curls into your routine. Periodically switching between the two techniques can promote muscle confusion and prevent plateaus, allowing for continuous gains.


In the world of weightlifting, the battle between alternating and bilateral curls rages on. While both techniques have their merits, it's crucial to choose the one that aligns with your goals and preferences. Whether you prioritize stability and coordination with alternating curls or seek maximum load capacity and symmetry with bilateral curls, consistency and proper form remain the key to unlocking those enviable arm gains. So pick your technique, grab those dumbbells, and let the curling commence. Your arms are about to enter beast mode!
