Dumbbell Seated Alternate Hammer Curl on Exercise Ball

Description

How to do Dumbbell Seated Alternate Hammer Curl on Exercise Ball

1. 01
   Setup

   Sit upright on an exercise ball with your feet flat on the floor, shoulder-width apart, ensuring your back is straight and core engaged.

2. 02
   Setup

   Hold a dumbbell in each hand with a neutral grip (palms facing each other), allowing your arms to hang fully extended by your sides.

3. 03

   Exhale as you curl one dumbbell upward towards your shoulder, keeping your elbow tucked close to your torso and only your forearm moving.

4. 04

   Squeeze your bicep at the peak of the contraction, then slowly lower the dumbbell back to the starting position with control as you inhale.

5. 05

   Immediately repeat the curling movement with the other arm, alternating sides for the duration of your set while maintaining core stability.

Tips

• Maintain constant tension on the exercise ball by keeping your core braced, which helps stabilize your torso and prevents unwanted swaying.
• Keep your elbows fixed at your sides throughout the entire movement to maximize bicep and forearm isolation and prevent shoulder involvement.
• Focus on a controlled eccentric (lowering) phase, taking approximately 2-3 seconds to return the dumbbell to the starting position to enhance muscle growth.
• Avoid using momentum to lift the weight; if you find yourself swinging the dumbbell, select a lighter weight to ensure strict form.

Common mistakes

• Using momentum to swing the dumbbells up reduces bicep engagement; instead, use a lighter weight and focus on a strict, controlled curl.
• Allowing your elbows to flare out from your sides reduces bicep isolation and can put strain on your shoulder joints; keep them tucked in.
• Losing core stability and rocking excessively on the exercise ball compromises form and can strain your lower back; brace your core to maintain a stable torso.
