How to do dumbbell one arm kickback
Master the setup, range of motion, and tempo for safer, more effective reps.
Overview
The Dumbbell One Arm Kickback is an isolation exercise that targets the triceps, specifically the long head. Because of the angle of your body, the resistance is highest at the very top of the movement when your arm is fully straight.
This isn't an exercise for 'ego lifting.' It’s about control, the mind-muscle connection, and holding that squeeze at the top. It’s a fantastic finishing move to polish off an arm workout.
Why Use It
- Provides a unique peak contraction that other tricep moves miss.
- Requires zero fancy equipment—just a dumbbell and something to lean on.
- Great for developing the 'horseshoe' look of the triceps.
When to Use It
Use this at the very end of your workout as a 'finisher.' It works best with higher reps and light to moderate weight.
Stats
Instructions for Proper Form
Setup
- The Support: Place one hand and knee on a flat bench. Your other foot should be on the floor.
- The Position: Hold a dumbbell in your free hand. Pull your elbow up until your upper arm is in line with your torso.
Execution
- The Kick: Keeping your upper arm perfectly still, straighten your arm to move the dumbbell back in an arc.
- The Squeeze: When your arm is fully straight, pause and squeeze your triceps for a full second.
- The Return: Slowly lower the weight back to the starting position (90-degree bend at the elbow).
Pro-Tip
The 'magic' of this exercise happens in the last two inches of the movement. If you don't get your arm perfectly straight, you're missing the best part of the rep!
Common Mistakes
- The Pendulum: Swinging the weight back and forth using momentum. This does nothing for your triceps!
- Dropping the Elbow: If your elbow points toward the floor, the gravity is no longer working against your triceps at the top.
- Rounded Back: Keep your spine neutral to avoid unnecessary back strain.
Mistakes by Level
Beginner
- Letting the elbow drop during the return phase.
- Not straightening the arm completely.
Intermediate
- Using a weight that is too heavy, leading to a 'jerking' motion.
- Rotating the torso to help lift the weight.
Advanced
- Rushing the eccentric (lowering) phase.
- Losing the peak contraction at the end of a set.

Setup Requirements
- Find a bench or a sturdy rack to lean on.
- Place one hand and the same-side knee on the bench, or stand in a staggered stance leaning forward.
- Keep your back flat like a tabletop.
- Pull your elbow up so your upper arm is parallel to the floor and tucked against your ribs.
Form Checklist
- Is my upper arm staying still, or is it dropping toward the floor?
- Am I using my shoulder to swing the weight?
- Am I getting my arm completely straight at the top?
- Is my back staying flat?
Range of Motion
Start with your elbow bent at 90 degrees. Extend your arm back until it is perfectly straight and parallel to the floor.
Breathing Pattern
Exhale as you kick the weight back; inhale as you slowly return to the 90-degree start position.
Tempo Guidance
1 second to kick back, a 1-second hard squeeze at the top, and 2 seconds to lower it back down.
Caution Notes
- If you find yourself swinging your torso to get the weight up, the dumbbell is too heavy. Drop the weight and focus on the squeeze.
Programming
Treat these guidelines as practical programming defaults, then scale load, volume, and frequency to match the rest of the training week.
Best For
- Defining the triceps.
- Finishing an arm workout.
- Training at home with limited equipment.
Goal Tags
Rep Ranges
- 12-15 reps for maximum blood flow and pump.
- 15-20 reps for endurance.
- 10-12 reps is the lowest you should go for this move.
Set Guidance
2-3 sets per arm is usually enough to finish the muscle off.
Rest Guidance
Minimal rest (30-45 seconds) to keep the intensity high.
Frequency
Can be done 2-3 times per week.
Pairings
- Pair with a Cable Pushdown for a total tricep burnout.
- Pair with a Concentration Curl for a focused arm finish.
Audience Notes
- Beginners often struggle to keep the elbow high—watch yourself in a mirror.
- Advanced lifters should focus on the 'isometric' hold at the top.
Substitution Targets
- Cable One-Arm Kickbacks for more consistent tension.
- Bench Dips if you don't have dumbbells.
Variations
Use progressions to increase difficulty when you master the movement, and regressions if you struggle with proper form or face mobility limitations.
Regressions
Cable Kickback
The cable provides constant tension, making it easier to feel the muscle working throughout the whole range.
Best for: Those who struggle to feel their triceps with dumbbells.
Progressions
Kickback with a Pause
Holding the top position for 3 seconds forces more muscle fiber recruitment.
Best for: Advanced lifters looking for more intensity without more weight.
FAQ
Common Questions
Is this better than a pushdown?
Not necessarily 'better,' but it hits the muscle differently. Pushdowns allow for heavier weight, while kickbacks provide a better peak contraction.
Can I do these standing?
Yes, just hinge forward at the hips so your torso is almost parallel to the floor. If you stand too upright, the exercise becomes a bicep curl for the wrong muscle!
