Dumbbell Alternate Z Press

Muscles worked

Setup

1. Sit on the floor with your legs extended straight out in front of you in a wide 'V' shape.
2. Hold a pair of dumbbells at shoulder height with a neutral or slightly pronated grip.
3. Sit tall on your sit-bones, engaging your core to maintain a perfectly vertical torso without leaning back.
4. Pull your shoulder blades down and back to create a stable pressing platform.

How to do it

1. Exhale as you press one dumbbell vertically until your arm is fully locked out overhead, keeping the other weight at shoulder height.
2. Inhale as you lower the weight back to the starting position with a controlled 2-second eccentric phase.
3. Immediately repeat the movement with the opposite arm, alternating sides for the duration of the set.
4. Maintain a steady tempo, ensuring the torso remains completely still as the weight shifts from side to side.

Form checklist

• Keep your spine neutral; do not lean back or arch your lower back as you press.
• Keep your legs pressed firmly into the floor and your quads flexed to assist with stability.
• Ensure the bicep finishes next to the ear at the top of the movement for full range of motion.
• Avoid shrugging the shoulders toward the ears; keep the traps relaxed.

Pro tips

• Imagine 'growing taller' through the crown of your head to maximize spinal alignment and core tension.
• Actively pull your toes toward your shins (dorsiflexion) to create a more rigid base of support through the lower body.

Make it harder

• Bring your legs closer together to narrow your base of support, significantly increasing the demand on your obliques and deep core.
• Add a 3-second isometric hold at the top of each repetition to challenge shoulder stability.
