Alternate Biceps Curl
This exercise is a classic :)
Standing in a split-stance position to stabilize your body, Your arms are at your sides, close to your body and your palms are facing forward. Pull the shoulder blades down and back. Your head and neck should be aligned with your spine. Do not allow the back to arch. Maintain these engagements throughout the exercise.
Slowly bend one elbow as the opposite arm should remain in the starting position. Keep your torso erect. Do not allow the elbows to move forward. Keep the palms facing forward and your wrists straight without any bend. Do not allow the shoulders to shrug.
Gently back to your starting position. Keep the dumbbell in the neutral position. Repeat to the opposite side.
