Dumbbell lying triceps extensions increase strength in the triceps. Performing the exercise with dumbbells will achieve muscular balance on both sides of the body.
Lie on a bench with dumbbells in each hand and your arms extended over your chest.
Bend your elbows and lower the dumbbells until they're just above your shoulders. Your upper arms shouldn't move. Pause and then extend the dumbbells back to the starting position by squeezing your triceps.
Do not place your feet on bench. Make sure feet are planted firmly on floor.
Do not allow your elbows to flare out to the sides.
