How to do the lying dumbbell tricep extension
- Lie on a flat bench while holding two dumbbells directly in front of you. Your arms should be fully extended at a 90-degree angle from your torso and the floor. The palms should be facing in and the elbows should be tucked in. This is the starting position.
- As you breathe in and you keep the upper arms stationary with the elbows in, slowly lower the weight until the dumbbells are near your ears.
- At that point, while keeping the elbows in and the upper arms stationary, use the triceps to bring the weight back up to the starting position as you breathe out.
- Repeat for the recommended amount of repetitions.
