Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Keep elbows close to your sides throughout the movement. Curl the bar towards your chest, contracting your biceps. Squeeze at the top, then slowly lower the bar to full arm extension, avoiding torso swing.
To maintain proper form, keep your elbows tucked tightly against your sides, preventing them from drifting forward or backward as you curl the weight. Focus on squeezing your biceps hard at the peak of the contraction to maximize muscle engagement and ensure you're using the intended muscles. Avoid swinging your body to generate momentum; instead, rely on your biceps strength to lift the weight, maintaining a stable core throughout the exercise. Control the descent of the bar, resisting the urge to let it drop quickly, as this eccentric phase is crucial for muscle growth and injury prevention.
