Dumbbell Tricep Extension -Pronated Grip
A lying extension done with two dumbbells, palms facing forward, lowering the weights beside your ears rather than to your forehead. Splitting the load across two independent bells lets each wrist and elbow find its own path, which is why it usually feels tolerable on days a straight bar does not.
Own the movement
Set up first, then execute. Every cue below is something you can check on your next set.
Before the first rep
- Sit on a flat bench with a dumbbell on each thigh, then kick them up as you lie back rather than curling them into place.
- Press both dumbbells to straight arms directly above your shoulders, palms facing forward.
- Tilt the upper arms back about 10-15 degrees toward your head so the triceps stay loaded at the top.
- Pull the elbows in toward each other — roughly shoulder-width — and keep them there.
- Plant both feet flat and press your lower back lightly into the bench before the first rep.
Every rep
Breathing & tempo — Inhale as the dumbbells travel down beside your ears, exhale as you extend. Three seconds down, a brief pause at the stretch, one second up.
Before you load it
- Do not lower the dumbbells onto your face. Lowering past your ears keeps the path clear even if one arm gives out first.
Sets, reps & load
Where to start, and what to change when it stops being hard.
Start with 6-8 kg per hand even if you bench well — the lever is long and the joint is unforgiving. Add 2 kg per hand once you can complete 15 reps with no elbow drift and no bounce off the bottom. Reps before weight is the right order on this one.
What goes wrong
The errors that show up most often, and the cue that fixes each one.
Imagine holding a folded towel between your elbows for the whole set. If they still spread, drop 3 kg per hand — flared elbows put the strain across the joint rather than through the triceps.
Keep the upper arms tilted 10-15 degrees back toward your head and turn round short of lockout. Vertical arms are a rest stop, and this variation exists to remove it.
Keep a straight line from knuckle to elbow and grip firmly. A collapsed wrist shifts the bell behind your hand and makes light weight feel unstable.
Pick a weight you can control for 12 reps with the upper arms motionless. This is elbow extension only; if the shoulders are helping, the exercise has become a press.
Why bother
A barbell locks both hands into one fixed spacing and one fixed rotation. If your elbows do not happen to like that geometry, the joint absorbs the mismatch. Two dumbbells let each arm settle into its own line, so the elbow flexes without a sideways twist being forced on it.
The pronated grip and the path past the ears also keep the upper arm slightly angled back rather than straight up, so tension stays on the triceps at the top instead of stacking the weight over a locked joint. It is a small change to the skullcrusher that removes most of its rest position.
Where it fits
After your heavy pressing on a push or upper day, 3-4 sets of 10-15. It works well immediately followed by a set of close-grip presses with the same dumbbells — when the extensions fail, flatten the arms out and press the remaining reps.

Asked and answered
Why dumbbells instead of an EZ bar?
Because each arm can rotate and space itself independently. A bar fixes both hands in one geometry, and if your elbows do not match it the joint eats the difference. If skullcrushers hurt your elbows, this is the first substitution to try.
To the ears or to the forehead?
Ears. The path past the head keeps the upper arm angled back, which holds tension on the triceps through the top of the rep and gives you an escape route if one arm fails. A forehead-bound bar has neither.
Should the palms face forward or each other?
Forward for this variation — it keeps the elbows tracking in a fixed plane. Palms facing each other is a neutral-grip version, slightly kinder to the elbow and a fine option, but it lets the arms wander more unless you are deliberate about it.
Can I do this on a decline bench?
Yes, and it keeps constant tension even better because the arms never reach a vertical rest position. The trade-off is a harder setup and more blood in your head. Use flat while you learn the pattern, then try decline for a change of stimulus.
