The last bicep curl tutorial you will ever need. First, grab a pair of dumbbells, stand upright and get into a stable shoulder width stance. You want to purposely loosen up your grip to minimize the activation of your forearm muscles. Tuck in your elbows close to your sides, bring your arms slightly forward, rotate the elbows in towards your hips and press your shoulders down. Start by bending the elbow and curling the weight out in front of you in an arc and focus on driving your pinkies up towards the ceiling for better biceps activation. Finish by pulling the dumbbell into your body until biceps are fully contracted. Do not allow your wrists to curl in at any point during the rep. Begin the eccentric by slowly resisting the weight back down and fully extend your arms before doing the next rep.
