Lie on a flat or incline bench holding dumbbells that are resting vertically on your chest. Your palms have to be facing away from your face and your elbows flared out.
This is your starting position.
Begin extending your arms just as you would with a regular triceps extension exercise, without moving your shoulders. In other words, try and move just the elbow joint to extend the arm and move the weight.
Similarly to the landmine press – extend your arm to the point where it’s almost straight. Do not lock your arms out as you would be putting a lot of unnecessary tension on your elbow joints and removing the stress away from the triceps muscle.
