Performing the: A Step-by-Step Tutorial Barbell Curl
Take a deep breath, brace your core, and slowly curl the barbell upward while keeping your upper arms stationary. The movement should only occur at the elbow joint.
Continue to lift the barbell until your biceps are fully contracted and the bar is at shoulder level. Hold the contracted position for a moment and squeeze your biceps.
Exhale and slowly begin to bring the bar back to the original position as your breathe in. Ensure that you're controlling the movement and not letting the barbell just drop back down.
Repeat the process for the recommended amount of repetitions.
