Focus on moving the weight with your triceps, keeping control of the weight as you slowly lower the dumbbells back to the starting position.
Keep your body as still as possible, moving only your forearms.
Keep your head up and eyes forward throughout the exercise.
Instructions
Select a pair of dumbbells and place them on the floor in front of a flat bench.
Sit on the edge of the bench and pick the dumbbells up from the floor using a neutral grip (palms facing inward).
Get into the starting position by keeping your back straight and bending over at the waist. Your torso should almost be parallel to the floor.
Tuck your upper arms close to your torso and bend at the elbows, forming a 90 degree angle with your upper arms and forearms. This is the starting position.
Moving only at the elbow joints, raise the dumbbells behind you until your arms are fully extended.
Pause, and then lower the dumbbells back to the starting position.
