The dumbbell triceps kickback isolates the triceps by pinning the upper arm parallel to the torso and extending only at the elbow. Simple, effective, and easy to feel — it’s the go-to isolation exercise for anyone who struggles to connect with their triceps.
What it is
The dumbbell triceps kickback is a triceps isolation exercise performed one arm at a time. The lifter hinges at the hips to bring the torso parallel to the floor, then pins the upper arm to the torso and extends the elbow to lift the dumbbell back until the arm is straight. The strict elbow-only movement isolates the triceps completely.
Muscles worked

How to dumbbell triceps kickback: 5 steps
-
Hinge and brace
**Hinge at hips, torso parallel to floor.** Support with opposite hand on a bench.
-
Pin upper arm
**Upper arm parallel to torso, elbow bent 90°.** Dumbbell hanging down.
-
Extend
**Extend the elbow only** — upper arm doesn't move. Dumbbell arcs backward.
-
Peak squeeze
**Fully extend, squeeze triceps at the top.**
-
Controlled return
**Lower over 2 seconds** back to 90° elbow bend. Complete reps, switch arms.
How it differs from cable kickback
- Dumbbell instead of cable. Gravity provides resistance — lightest at bottom, heaviest at extension.
- Peak contraction focus. Load is highest at the fully-extended position.
- Portable exercise. No cable machine needed — just a dumbbell and a bench.
- Lower total load. Dumbbell kickback loads lighter than cable — 60-70 % of cable weight.
Common mistakes
When to use this variation
Use dumbbell triceps kickbacks as an isolation finisher or when working out at home with limited equipment. Program 3 sets of 12-15 reps per arm. Pair after heavier compound triceps work for a focused pump.
FAQ
How heavy a dumbbell?
Light — 3-8 kg for most intermediate lifters. Chasing weight kills form on this exercise.
Dumbbell or cable kickback?
Cable provides constant tension. Dumbbell peaks at the extended position. Both work; cable is slightly superior for muscle stimulus.
Standing or hinged?
Hinged (torso parallel to floor) is standard and gravity-correct. Standing versions don’t align gravity with the triceps.
