Standing Bent-Over Two-Arm Dumbbell Triceps Extension
The standing bent-over two-arm dumbbell triceps extension has you hinge forward at the hips and extend both elbows behind you, working the triceps through a stretched, overhead-free range of motion. It isolates the back of the upper arm without needing a bench, so it works anywhere you have two dumbbells and room to bend forward. Beginners use it to build triceps strength and control before loading heavier pressing movements.
Why it works
Your triceps' main job is elbow extension, and this exercise strips away almost everything else. Bending forward at the hips takes the lower back and legs out of the equation, and keeping your upper arms pinned close to your torso means the shoulders barely move either. What's left is a long lever arm, from your pinned elbow to the dumbbell in your hand, that the triceps alone has to extend against gravity. That long lever creates real tension even with moderate dumbbells, and the hinged position lets you load the stretched position of the triceps more directly than most pressing exercises do. Because your arm swings through a wide arc behind your torso instead of straight down, the long head of the triceps, the portion that crosses the shoulder joint, gets pulled through a longer stretch than it would in a straight-down pushdown.
Set up
- Grab a dumbbell with each hand, then lean forward from the hips until your torso is close to parallel with the floor.
- Pin your upper arms against your sides with your elbows bent to roughly 90 degrees, dumbbells near your ribs.
- Keep a slight bend in your knees and brace your core to support your lower back in the hinged position.
How to do it
- Without moving your upper arms, straighten both elbows to extend the dumbbells behind you.
- Squeeze your triceps hard at the top, where your arms are fully extended behind your torso.
- Pause for a beat at full extension.
- Bend your elbows to lower the dumbbells back to the starting position with control.
- Keep your torso still throughout; the movement should only happen at the elbow.
Form cues
- Upper arms pinned to your sides the whole set.
- Hinge, don't round, your lower back.
- Extend fully, squeeze, then control the way back.
- Move only at the elbow, not the shoulder.
Breathing: Exhale as you extend your elbows back, inhale as you bend them to lower the dumbbells.
Common mistakes
Letting the upper arms swing or lift away from the torso during the extension.
Fix: Keep your elbows pinned to your sides and check in a mirror or on video that only your forearms are moving.
Rounding the lower back instead of hinging from the hips to get into position.
Fix: Set the hinge with a flat back and soft knees before you pick up the dumbbells, then hold that position.
Stopping short of full elbow extension, so the triceps never get the end-range squeeze.
Fix: Finish each rep by locking the elbows out fully behind you and pausing there before lowering.
How to program it
- This is an isolation move for a small muscle group, so 2 to 3 sessions a week works well once you've built up some tolerance.
- Pair it toward the end of an upper-body or arm session, after your heavier pressing work is done, since fatigued triceps make those presses weaker.
- Sets of 10 to 15 reps let you feel the stretch and squeeze clearly; very heavy, low-rep loading tends to pull the elbows out of position.
Safety notes
- Stop if you feel strain in your lower back rather than your triceps; that usually means the hinge has broken down into rounding.
- Use a weight light enough that your upper arms stay still for every rep; swinging the dumbbells to finish a rep is a sign to drop the load.

Frequently asked questions
How many sets and reps should I do for this exercise?
Three sets of 10 to 15 reps is a solid starting point. The triceps respond well to moderate reps here since the exercise is about controlling a stretch and squeeze, not moving maximum weight.
Can I do this without a bench?
Yes, that's the point of the standing version. You only need two dumbbells and enough room to hinge forward at the hips.
Why do my shoulders hurt during this instead of my triceps?
That usually means your upper arms are drifting away from your torso, which shifts the work into the shoulder. Pin your elbows to your sides and only move at the elbow joint.
What's a good alternative if hinging forward hurts my lower back?
Try the seated bent-over two-arm dumbbell triceps extension instead. Sitting removes the hip hinge and gives your lower back more support while you train the same muscle.
Does this exercise hit the long head of the triceps more than a pushdown does?
Yes, more so. Extending your arm behind your torso rather than straight down stretches the long head, the portion of the triceps that crosses the shoulder joint, through a longer range than a straight-ahead cable pushdown allows.
