One Arm Bent Over Dumbbell Kickback Overview
The one arm bent over dumbbell kickback works your triceps. The triceps are the muscles on the back of your arms. You use one dumbbell. You lean on a bench with one knee and hand. You raise your elbow to your side. Then you swing your forearm back until your arm is straight. This shapes and builds your triceps. It also works your rear shoulder a little. This move gives your triceps a hard squeeze at the top. It is simple and great for beginners. Working one arm fixes a weak side. It is light and easy on the joints. Use it on push day or arm day. It works best as a finisher after bigger presses.
What Is The Point of the One Arm Bent Over Dumbbell Kickback?
The one arm bent over dumbbell kickback targets your triceps to build stronger, more defined arms. It isolates the back of your arms better than most exercises.
How To Do The One Arm Bent Over Dumbbell Kickback
- Grab a dumbbell in your right hand and place your left knee and left hand on a flat bench for support. This braced position keeps your back safe and lets you focus on the working arm.
- Set your back flat and roughly parallel to the floor, with your spine long and your core braced. Let your right arm hang straight down with the dumbbell to start.
- Pull your right elbow up until your upper arm is tight against your side and parallel to the floor. Lock the elbow in this position because it stays put for the whole set.
- Set your shoulder blade back so you are not shrugging, and keep your neck neutral by looking down at the bench. This is your starting position.
- Keeping your upper arm glued in place, extend your forearm back until your arm is completely straight. Drive the movement purely from the triceps, not from swinging your shoulder.
- Squeeze your triceps hard at full extension and hold for a beat. The kickback loads the triceps most at the top, so that squeeze is where the growth happens.
- Lower the dumbbell back to the starting position slowly, taking about two seconds and keeping your upper arm still. Do not just let the weight drop back down.
- Keep your torso motionless throughout, resisting any urge to twist or rock to help the weight up. Only your forearm should move.
- Finish all your reps on the right arm, then switch sides. Aim for 12 to 15 reps per arm for 3 to 4 sets, since the kickback works best with lighter weight and higher reps.
One Arm Bent Over Dumbbell Kickback Form Tips
- Keep your upper arm still and pinned to your side.

- Squeeze your triceps hard at the end of each rep.
- Keep your back flat, not rounded.
- Move slow. No swinging the weight.
- Keep your elbow high the whole time.
- Breathe out as you extend your arm.
- Keep your neck in line with your back.
Common Mistakes to Avoid for the One Arm Bent Over Dumbbell Kickback
- Letting your upper arm drop as you extend. The kickback only works if the upper arm stays parallel to the floor and pinned to your side, so a sagging elbow turns it into a weak half-rep. Lock your upper arm in place and move only at the elbow.
- Swinging the weight up with your shoulder. If you heave the dumbbell back using your shoulder and body, the triceps barely fire and you just build momentum. Keep your torso and upper arm still so the triceps have to do all the work.
- Not straightening the arm fully. Stopping short of lockout skips the peak contraction where the triceps work hardest in this movement. Drive the arm completely straight and squeeze before you lower.
- Going too heavy for a kickback. Too much weight forces you to swing and prevents you from locking out cleanly, which defeats the whole exercise. Pick a lighter dumbbell you can extend fully with good control.
- Rushing the lowering phase. Letting the weight drop back fast throws away the eccentric and takes tension off the triceps. Lower over about two seconds and keep the upper arm fixed the whole way.
- Rounding your back over the bench. A rounded spine under load puts your lower back at risk and pulls your focus off the arm. Keep your back flat and long with your core braced and supported by your bench hand.
- Shrugging your shoulder up toward your ear. A shrugged shoulder steals the movement from the triceps and can strain the joint. Set your shoulder blade back and down and keep your neck neutral.
- Twisting your torso to finish the rep. Rotating your body to fling the weight back cheats the triceps and stresses your spine. Stay square to the bench and let only your forearm move.
- Bouncing at the bottom into the next rep. Using a bounce at the start robs the triceps of tension and relies on momentum. Pause briefly at the bottom and start each rep under control.
- Cutting the reps too low with heavy weight. Kickbacks shine as a higher-rep squeeze exercise, so heavy low-rep sets just invite swinging. Keep the load moderate and push the reps into the mid-teens.
- Doing uneven work between arms. Your dominant arm usually grinds out cleaner reps, which slowly builds an imbalance. Match the reps and quality on both arms and let the weaker side set the standard.
One Arm Bent Over Dumbbell Kickback Workout Tips
- Treat the kickback as a peak-contraction exercise. It loads the triceps hardest at full lockout, so make a hard squeeze at the top the whole focus of every rep.
- Keep your upper arm locked parallel to the floor. Pinning the elbow in place is the key cue that keeps tension on the triceps instead of your shoulder taking over.
- Use lighter weight than your ego wants. The kickback rewards control and a full lockout, so a lighter dumbbell you can straighten cleanly beats a heavy one you swing.
- Squeeze and hold at full extension. A one second hold at the top drives the mind-muscle connection and makes each rep far more effective.
- Control the lowering for about two seconds. A slow eccentric keeps tension on the triceps and builds more muscle than letting the weight fall back.
- Aim for 12 to 15 reps for 3 to 4 sets. Higher reps suit this movement and give you the triceps burn that drives growth without forcing you to swing.
- Brace hard on the bench for a stable base. Supporting your torso with your other hand keeps your back safe and lets you isolate the working arm.
- Program it as a triceps finisher. It works great at the end of a push or arm day after heavier pressing to fully fatigue the triceps.
- Chase the mind-muscle connection. Think about driving through your triceps to straighten the arm, since feeling the muscle work is one of the best ways to build it.
- Keep your shoulder set and still. A stable, un-shrugged shoulder keeps the load on the triceps and protects the joint.
- Match your reps on both arms. Most people have a stronger side, so let the weaker arm set the rep count to keep your triceps balanced.
- Film yourself from the side. A quick video shows whether your upper arm is staying put or drifting, which is hard to feel in the moment.
- Try a slight pause at the bottom. Killing the bounce forces the triceps to start each rep from a dead stop, which sharpens the isolation.
- Keep your wrist neutral and firm. A stable wrist keeps the dumbbell under control and stops strain from creeping into the joint.
- Warm up your elbows first. A few light reps prep the tendons so your working sets feel smooth and pain-free.
- Be consistent for horseshoe triceps. The kickback is a great detail exercise, so regular work over time helps carve out the back of the arm.
