Keep your elbows close to your torso at all times. This will be your starting position.
Now, while keeping your upper arms stationary, exhale and curl the weights while contracting your biceps. Continue to raise the weights until your biceps are fully contracted and the bar is at shoulder level. Hold the contracted position for a brief pause as you squeeze your biceps.
Then inhale and slowly begin to lower the bar back to the starting position.
Repeat the process for the recommended amount of repetitions.
Pro Tip
Control Your Movements: Avoid using your back or shoulders to lift the weight. The power should come from your biceps. Make sure to control the movement both on the way up and on the way down. A common mistake is to let the barbell drop quickly after the curl, but you should resist the weight on the way down for maximum muscle engagement. Don't Overload the Barbell: While it might be tempting to lift heavy weights, it's important to use a weight that allows you to complete the exercise with proper form. Lifting too heavy can lead to injury and won't necessarily lead to better results. Full Range of Motion
