How to do Close-Grip Barbell Curl:
Step 1: Grasp a barbell with both hands. Your palms should be up and a few inches apart.
Step 2: Stand up, keeping your torso straight and your head up. Your feet should be positioned about shoulder width apart, and your elbows should be held close to your torso. This is the starting position.
Step 3: Curl the bar upward using a semicircular motion; your forearms should be touching your biceps. Exhale as you do so. Contract your biceps for a second at the top.
Step 4: Move slowly back to the starting position. Inhale as you do so.
Step 5: Repeat for the number of reps in your set.
