Inhale as you slowly lower the dumbbells to the starting position.
Comments and tips
Only your forearms should move. Keep your upper arms horizontal and locked to your sides.
While the seated bent-over two-arm dumbbell kickback recruits no synergistic muscles, the muscles listed as stabilizers contract to keep your upper arm horizontal.
This exercise is essentially the same as the dumbbell kickback. As mentioned on the dumbbell kickback page, the dumbbell kickback is very effective at activating your triceps. In one study that compared triceps exercises for effectiveness, it came second, to be beaten only by the diamond push-up.
Keeping your upper arms horizontal when holding a heavy weight can be difficult. Therefore, if you want to lift heavy, use the cable kickback instead.
