7 Best Biceps Exercises for Bigger Arms (science-based)

The first biceps exercise to perform is barbell biceps curls, which will also allow you to overload those biceps with a heavy weight. Most trainees are slightly stronger when lifting a barbell versus a set of dumbbells, so this is a great one for maximum strength development.
When doing the exercise, the primary thing to focus on is that you’re not cutting the movement pattern short at all, and that you’re not allowing momentum to cause you to lean backward as you hoist the weight upwards.
This is one of the most common mistakes with this exercise—momentum performs more of the work than your muscles actually do. If you perform it in a slow and controlled manner, that should reduce the chances of this happening significantly and allow you to place a higher intensity deep within the muscle fibers.The second exercise to add is incline dumbbell curls. This exercise is one of the best to help prevent that momentum issue from happening as we just discussed, since it essentially restricts the movement of the back.Stand up with your torso upright while holding a cable curl bar that is attached to a low pulley. Grab the cable bar at shoulder width and keep the elbows close to the torso. The palm of your hands should be facing up (supinated grip). This will be your starting position.
While holding the upper arms stationary, curl the weights while contracting the biceps as you breathe out. Only the forearms should move. Continue the movement until your biceps are fully contracted and the bar is at shoulder level. Hold the contracted position for a second as you squeeze the muscle.
Slowly begin to bring the curl bar back to starting position as your breathe in.
