How To Do a Bicep Curl Properly (Build Bigger Arms)

Most people turn the bicep curl into a full-body movement… swinging the weight and letting their shoulders do the work. If you actually want your biceps to grow, the setup matters. Start by engaging your core and standing tall so your body stays stable. Keep your elbows tucked close to your sides and focus on elbow flexion. Your elbow should stay in place while the forearm moves. Curl the dumbbell up under control and squeeze the bicep at the top, bringing the dumbbell slightly toward your shoulder for a stronger contraction. No swinging. No momentum. Just controlled tension on the biceps. Do it right and even lighter weights will feel brutal.
