Dumbbell Floor Lying Single-Arm Hammer Press

Lie flat on your back on the floor holding a single dumbbell with a neutral hammer grip and lift your straight legs slightly off the ground.

Engage your core to press your lower back firmly into the floor and place your free hand lightly on your stomach for balance.

Press the dumbbell straight up toward the ceiling until your arm is fully extended above your chest.

Slowly lower the dumbbell back down until your upper arm rests gently on the floor before repeating.
