How do correctly do a Bicep Curl!

One of the most common exercises you’ll see in any strength studio is the bicep curl — but it’s also one of the most commonly performed incorrectly. As instructors, we see it all the time: weights swinging, elbows drifting forward, and momentum doing more of the work than your muscles.

You’ve probably noticed it yourself — maybe in class or scrolling through Instagram. Those big swings might look powerful, but they’re actually taking the focus away from what you’re trying to train: your biceps.

So, can you spot a correct bicep curl when you see one?
Elise recently shared a video on Instagram — take a look and see if you can tell which one’s right. 👀

Making sure you are paying attention! 🙂
Both are the same video and are CORRECT. So lets go over the keys to doing a correct bicep curl:

  • Keep your elbows pinned to your sides (they shouldn’t move forward or back)
  • Shoulders stay relaxed, not hunched
  • Grip the weights with palms facing up and wrists straight
  • Curl the weights up slowly and with control, keeping tension on the biceps
  • Don’t swing your arms or use momentum — isolate the movement
  • Squeeze your biceps at the top
  • Lower the weights slow and controlled to full extension (don’t drop them)
