Dumbbell Kickback
The Dumbbell Kickback is a strict arm exercise that focuses on control and full extension to build stronger, more defined arms.
Dumbbell Kickback
The Dumbbell Kickback is a single-arm triceps exercise performed in a bent-over position, extending the arm from a bent elbow to full lockout behind the body. The position limits momentum and forces strict control through the entire range, making even lighter loads highly effective for isolating the triceps.
Dumbbell weight selection during kickbacks significantly affects both joint forces and triceps activation, with proper loading being essential for maximizing muscle engagement while keeping elbow stress manageable (Serbest et al., 2025). Keep your torso stable, your upper arm pinned to your side, and move only through the elbow with a slow, controlled tempo. The peak contraction occurs at full extension, so squeeze deliberately at the top of each rep.
Higher training volumes enhance muscle thickness in resistance-trained individuals (Brigatto et al., 2022), and the kickback is well suited for accumulating volume on the triceps without taxing the shoulders or chest. Allowing adequate rest between sets further supports strength and hypertrophy gains (Schoenfeld et al., 2016).
Program this exercise at the end of an arm workout or as a focused accessory movement. Reduce the weight and shorten the range to make it easier, or slow the lowering phase to increase difficulty while maintaining strict form.

Technique and form
How to perform the Dumbbell Kickback
- Stand with feet hip-width apart holding a dumbbell in each hand, then hinge forward at the hips until your torso is nearly parallel to the floor.
- Draw your shoulders back and down, keeping your spine neutral and core engaged throughout the movement.
- Bend your elbows to approximately 90 degrees, bringing your upper arms close to your sides and parallel to the floor.
- Inhale and brace your core, maintaining this stable bent position with your upper arms as your anchor point.
- Exhale as you extend your elbows, straightening your arms backward until the weights are pointing toward the wall behind you.
- Squeeze your triceps at the top of the movement, ensuring your upper arms remain stationary against your sides.
- Inhale as you slowly bend your elbows, returning to the starting position in a controlled manner.
- Maintain your hinged position throughout the set, keeping your neck aligned with your spine and gaze directed at the floor a few feet in front of you.
Important information
- Keep your upper arms completely still throughout the movement; only your forearms should move.
- Avoid using momentum or swinging the weights; use a controlled tempo to maximize tricep engagement.
- If you feel your lower back arching, reduce the weight or take brief breaks between reps while maintaining your position.
- For greater stability, you can perform this exercise with one arm at a time, placing your free hand on a bench or your thigh for support.

Muscles Worked: Dumbbell Kickback
The Dumbbell Kickback is an isolation exercise that focuses your effort on the triceps. Here's a breakdown of every muscle involved.
Primary muscles
Triceps — Your triceps extend your elbows and lock out the movement. These are the main muscle doing the heavy lifting during the Dumbbell Kickback.

FAQ - Dumbbell Kickback
Dumbbell kickbacks primarily target the triceps brachii, with emphasis on the lateral head that creates the horseshoe appearance. The exercise particularly activates the muscle during the final extension phase, making it excellent for developing definition in the back of your arms.
Position yourself in a split stance with your non-working hand and knee on a bench, keeping your back flat and parallel to the floor. Hold the dumbbell with your working arm, keeping your upper arm parallel to your torso throughout the movement, and extend at the elbow until your arm is straight without rotating your shoulder or swinging the weight.
Choose a weight that allows you to maintain strict form while completing 10-15 repetitions for hypertrophy or 8-12 reps for strength development. Most lifters benefit from lighter weights (5-20 pounds) as this exercise is most effective when focusing on complete contraction rather than moving heavy loads.
The most common errors include using momentum to swing the weight, dropping the elbow below torso level during the movement, and selecting weights that are too heavy. Also avoid rounding your back or rotating your shoulder during the extension, as these compensations reduce triceps activation and may lead to shoulder strain.
Once you've mastered the standard form, try variations like single-leg kickbacks for added core engagement, cable kickbacks for consistent tension, or incorporate tempo training with slow negatives (3-4 second lowering phase). You can also experiment with different grip positions or add a brief pause at full extension to maximize the contraction.
