Bench dips
Why it's worth doing
Bench dips train the triceps with minimal equipment, just a bench, nothing else, in a movement that doesn't depend on having parallel bars around or on tolerating your full bodyweight hanging from your arms, the way parallel-bar dips do.
That cost doesn't weigh the same for everyone: someone with no shoulder history and good internal-rotation mobility can handle real volume in this position, while someone who's already felt a rotator-cuff twinge on a press or a dip should treat this exercise as the first one to cut, not the last. The debate among coaches is real, but it isn't a blanket call to avoid it — it's a call to size up each person's shoulder before adding it in.
That doesn't make it an exercise to write off outright: keeping the range to about 90 degrees of elbow bend, without going deeper than that, cuts down quite a bit on the time the shoulder spends in its most loaded position. With that technique, and with no history of shoulder pain, it stays a valid option when a bench is all that's around.
In practice, it works better as an accessory to add triceps volume at the end of a pushing session than as a main movement: the technique is simple to learn, it doesn't require any unusual equipment, and the difficulty adjustment, moving the feet closer to or farther from the bench, adapts it to almost any level without needing an assisted machine or bands.
How to do it
- Sit on the edge of the bench and place your hands beside your hips, fingers pointing forward.
- Extend your legs out in front with your heels on the floor, or bend your knees for an easier version.
- Slide your hips off the bench until your arms alone are holding you up, elbows nearly straight.
- Lower yourself by bending your elbows backward, keeping them close to your body instead of flaring out to the sides.
- Stop once your arm reaches about 90 degrees of bend; going lower than that adds nothing for the triceps and asks more of the shoulder.
- Push back up by extending your elbows, without locking them out hard at the top.
- Repeat without letting your shoulders creep up toward your ears or your hips drift off the vertical path.

Muscles worked
The prime mover is the triceps brachii, mainly its lateral and medial heads, finishing elbow extension against the weight of the body. The long head contributes a bit less than it does in exercises where the arm sits overhead, like the dumbbell skull crusher, because here the shoulder stays in extension instead of flexion.
The front delt helps out as a secondary mover, mostly during the final part of the push back up. As stabilizers, the rotator cuff and rear delt take on harder work here than in most triceps exercises: they hold the head of the humerus in an internally rotated position with the arm behind the body, which is exactly the combination that generates most of the debate around this exercise.
The mid-traps and rhomboids pin the shoulder blade in place to give the shoulder a base to work from, and the core stays active isometrically, keeping the hips lined up with the shoulders through the whole range instead of letting them sag toward the floor.
Common mistakes
- Lowering past about 90 degrees of elbow bend: the shoulder starts absorbing the extra weight without the triceps getting anything more out of it.
- Letting the elbows flare out to the sides instead of staying close to the body: changes the working angle and asks more of the shoulder.
- Letting the shoulders creep up toward the ears through the whole range: removes stability right where the shoulder needs it most in this position.
- Moving the feet away from the bench before the bent-knee version's technique is solid: adds difficulty before there's a base to hold it up.
Bench dips or parallel-bar dips
Bench dips or parallel-bar dips is a comparison that gets confused by the shared name, but these are two different exercises with a pretty different demand on the shoulder.
On parallel bars, the whole body hangs from the support point with the arms at your sides, and the shoulder works through extension, a range the shoulder tolerates reasonably well even under heavy load. It's also a compound movement: on top of the triceps, it trains the chest hard when the torso leans forward.
On a bench, the arm sits behind the body and the shoulder works through internal rotation, the position the rotator cuff handles least comfortably. In exchange, it doesn't require holding up your full bodyweight hanging in the air, your feet stay planted somewhere, which makes it more accessible for someone who doesn't yet have the shoulder strength parallel-bar dips ask for.
The real debate among coaches isn't about which one to use all the time; it's that plenty of them save parallel-bar dips for whenever bars are available and treat the bench version as a stand-in for when they aren't, not as an equal alternative. For someone with no shoulder history and bars within reach, parallel bars tend to be the option with less joint compromise; the bench version stays useful when that equipment isn't around.
Frequently asked questions
Are bench dips the same as parallel-bar dips?
No, even though they share a name and target the same muscle. On parallel bars the body hangs with the arms at your sides and the shoulder moves through extension; here the arms sit behind the body, resting on the bench, and the shoulder works through a much more pronounced internal rotation. They're different exercises with a different demand on the shoulder, even if the muscle target looks similar.
Why do some coaches avoid recommending bench dips?
Because having the arm behind the body, with the shoulder rotated inward and carrying load in that position, is one of the positions the rotator cuff tolerates worst. It isn't dangerous for everyone, but it's the concrete reason plenty of coaches reach for parallel-bar dips or another triceps exercise instead, when the goal is minimizing shoulder stress, not just training the triceps.
How low should I go?
Until your arm gets close to 90 degrees of bend, not lower. Past that point, joint discomfort at the front of the shoulder usually shows up before the triceps get any extra stimulus, so going deeper doesn't buy anything and just adds risk.
How do I progress this exercise?
By moving your feet farther from the bench a little at a time; the farther out your heels sit, the more bodyweight lands on your arms. Raising your feet onto another bench is the next step, and only after that does it make sense to rest a plate on your hips.
Does hand position on the bench matter?
Yes: fingers pointing forward, hands set beside your hips, keep your wrists in a neutral position through the whole range. Turning your hands outward can feel more comfortable at first, but it changes the wrist angle under load and doesn't add anything for the triceps.
Similar exercises
Triceps pushdowns train the same muscle without asking the shoulder for any extreme position: the arm stays close to the body through the whole range, making it the most direct way to add triceps volume without the internal rotation that defines bench dips.
The dumbbell skull crusher hits the triceps from the opposite end, with the arm overhead instead of behind the body, stretching the long head in a position neither dip variation comes close to demanding.
