Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Stand with feet shoulder-width apart, holding an EZ bar with a close, palms-up grip. Keep elbows close to your torso and knees slightly bent. Exhale and curl the bar upwards, flexing your biceps and keeping upper arms stationary. Lift until the bar reaches shoulder level. Pause, then slowly lower the bar back to the starting position while inhaling. Repeat.
Keep elbows close to your body. Avoid swinging; focus on controlled movements. Maintain straight wrists. Engage your core for stability. Adjust grip width for wrist comfort.
