Source Free Exercise DB · 2026-07-10
Seated Bent-Over Two-Arm Dumbbell Triceps Extension is documented from the Free Exercise DB (CC0) extract, last ingested July 2026. Classification, muscle roles and instruction text are source facts; the placement and cohort measures on this page are computed by PlainExercise and are not a rating of the movement.
What the Seated Bent-Over Two-Arm Dumbbell Triceps Extension Data Reveals · DEEP · PUSH/ISOLATION
Seated Bent-Over Two-Arm Dumbbell Triceps Extension stands out on mechanic class: joint involvement separates this page from isolation peers.
Longer step lists usually mean finer setup cues, not a harder movement by themselves.
Across 71 catalogued triceps movements, the average instruction record is 744 characters and 4.7 steps; 58 of those (81.7%) clear the same ≥500-character rich bar used here. This page ranks #9 of 71 by instruction-character length (1.39× the cohort average).
Among the 123 exercises that also use a dumbbell, average instruction length is 790 characters; 19 of those peers are longer than this record. Equipment-matched peers are the honest comparison when you are choosing a substitute implement for the same pattern.
Other well-documented triceps movements (same ≥500-character bar):
- Tate Press (5 steps, 1,214 chars)
- Lying Close-Grip Barbell Triceps Extension Behind The Head (5 steps, 1,163 chars)
- Pin Presses (6 steps, 1,139 chars)
- Weighted Bench Dip (5 steps, 1,139 chars)
- Dumbbell One-Arm Triceps Extension (6 steps, 1,118 chars)
Context matters: taxonomy (level, mechanic, force, musculature, equipment) does not account for individual biomechanics, joint history, or recovery.

Consult a physician or certified trainer before starting, especially with injuries, cardiovascular conditions, recent surgery, or pregnancy.

Muscles worked
The Free Exercise DB classifies each muscle as primary or secondary. It does not measure activation, so we show involvement, not percentages.

Intensity context
For reference, here is where common activities sit on the MET intensity scale. Seated Bent-Over Two-Arm Dumbbell Triceps Extension does not have a measured MET in the source data, its intensity depends on the load and effort you use. Estimate calories for any activity with the calorie calculator.
MET values from the Compendium of Physical Activities (Ainsworth et al., 2011). A general reference scale, not a rating of this specific movement.
How to do it
- Sit down at the end of a flat bench with a dumbbell in both arms using a neutral grip (palms of the hand facing you).
- Bend your knees slightly and bring your torso forward, by bending at the waist, while keeping the back straight until it is almost parallel to the floor. Make sure that you keep the head up.
- The upper arms with the dumbbells should be close to the torso and aligned with it (lifted up until they are parallel to the floor while the forearms are pointing towards the floor as the hands hold the weights). Tip: There should be a 90-degree angle between the forearms and the upper arm. This is your starting position.
- Keeping the upper arms stationary, use the triceps to lift the weight as you exhale until the forearms are parallel to the floor and the whole arm is extended. Like many other arm exercises, only the forearm moves.
- After a second contraction at the top, slowly lower the dumbbells back to the starting position as you inhale.
- Repeat the movement for the prescribed amount of repetitions.
Common mistakes
- Rushing through reps, controlled tempo (2-3s down, 1-2s up) is what drives muscle tension on Seated Bent-Over Two-Arm Dumbbell Triceps Extension, not raw speed.
- Cutting the range of motion short - moving the triceps through its full safe range on Seated Bent-Over Two-Arm Dumbbell Triceps Extension is what most reliably separates effective reps from wasted ones.
- Using momentum instead of muscle, isolation movements like Seated Bent-Over Two-Arm Dumbbell Triceps Extension reward strict form. If you're swinging the weight, it's too heavy.
- Flaring elbows excessively on push movements, tucked elbows protect the shoulder joint and transfer more force into the target muscles.
- Breathing out of sync with the lift on Seated Bent-Over Two-Arm Dumbbell Triceps Extension - brace and inhale during the lowering phase, exhale on the exertion, especially important with a dumbbell where control matters most.
Who this is for
- People with 6+ months of consistent training who can perform basic compound lifts with good form
- People who want to train the Triceps
- People who have access to a dumbbell
Who this is NOT for
- People hunting equipment swaps, this record has none to offer; browse the peer triceps exercises for alternate patterns instead.
- Anyone with acute pain in the joints or muscles involved, pain is a stop signal, not a soreness signal
- People with unresolved injuries in the loaded joints, seek clearance from a physical therapist first
- Anyone with a recent surgery, cardiovascular limitation, or pregnancy complication without physician clearance
Progression path
Once Seated Bent-Over Two-Arm Dumbbell Triceps Extension feels comfortable with your current load, progress by (a) adding reps until you can complete 12+ per set, (b) increasing resistance by 2.5-5%, (c) moving to harder variations such as single-limb or longer lever versions, and eventually (d) stepping up to expert-level movements that train the same muscle.
See the Progression guide for a full framework on when to advance, and the Compound vs Isolation guide to decide when to prioritize this movement in your program.
Safety notes · DUMBBELL · PUSH/ISOLATION · MID
- Intermediate PUSH/ISOLATION: warm up mobility matching triceps before Seated Bent-Over Two-Arm Dumbbell Triceps Extension with a dumbbell.
- Sharp or joint pain is a stop signal. Muscle soreness during sets is normal; pain is not.
- Adjust sets, reps, and rest to recovery; 6 upstream steps are a template, not a prescription.

Using the seated bent-over two-arm dumbbell triceps extension
Three ways to put it to work.
- Train the triceps 2–3 times a week with 48+ hours between hard sets; pair this with other triceps movements for balanced development. All triceps exercises
- Match the load and rep range to your goal, strength, size, or endurance each call for a different scheme. Strength vs hypertrophy
- As an isolation movement, use it to target the triceps directly after your compound lifts. Compound vs isolation
Form before load. If a movement causes sharp or joint pain, stop and substitute a safer alternative, this is general information, not medical or training advice.
