The dumbbell woodchopper traces a diagonal path from high on one side to low on the other, holding a single dumbbell in both hands. The obliques drive the rotation while the hips and shoulders sequence into it, which makes the movement closer to a throwing or swinging action than to a crunch. Because the load travels a long arc, control matters more than weight here. A light dumbbell moved deliberately trains the pattern better than a heavy one thrown by momentum.
Muscles Targeted
- Primary: Internal and external obliques
- Secondary: Rectus abdominis, transverse abdominis, gluteus maximus
- Tertiary: Shoulders, lats, quadriceps
Starting Position
Stand with the feet slightly wider than shoulder-width, knees soft, holding one dumbbell in both hands. Lift the dumbbell above and outside one shoulder with the arms nearly straight, letting the torso rotate toward that side and the rear heel turn slightly. Brace the trunk and keep the ribs pulled down. The gaze follows the dumbbell so the neck rotates with the torso rather than against it.
Execution Steps
- Set the stance slightly wider than the shoulders with the knees softly bent.
- Raise the dumbbell above one shoulder and let the torso rotate toward that side.
- Brace the trunk hard, then start the movement by turning the hips, not the arms.
- Chop diagonally down and across the body, finishing just outside the opposite hip and knee.
- Control the finish with the arms straight and the trunk still braced, then pause.
- Reverse the path slowly back to the start, resisting the pull on the way up.
Form Cues
- Hips first: the rotation starts at the pelvis, and the arms simply carry the load along.
- Arms long, not stiff: keep a small elbow bend and let the shoulders travel with the torso.
- Turn the back foot as the hips rotate rather than grinding the knee.
- Keep the dumbbell close enough that the shoulders never feel yanked at the end range.
- Slow the return so the eccentric half of the rep is trained too.
Common Mistakes
- Using the arms alone: swinging with the shoulders while the hips stay square removes the obliques from the movement entirely.
- Going too heavy: a dumbbell that has to be thrown turns a controlled rotation into momentum the trunk never resists.
- Rounding the lower back: bending forward instead of rotating loads the lumbar spine in a twisted position.
- Locked feet: keeping both heels pinned to the floor forces the rotation down into the knees and the lower back instead.
- Dropping the return: letting the dumbbell swing back up to the start position skips the eccentric half of the working range.
Variations
- Cable woodchopper: constant tension through the whole arc of the movement.
- Low-to-high chop: reverse the direction to train the opposite rotation pattern.
- Half-kneeling chop: one knee down to remove leg drive and isolate the trunk.
- Medicine ball chop and throw: adds an explosive power element for athletes.
- Banded woodchopper: resistance rises steadily as the movement finishes across the body.
Tips for Progression
- Slow the return to three seconds before adding any extra weight to the movement.
- Add a one-second pause at the finish position of every single repetition.
- Progress from standing to half-kneeling to remove the leg contribution entirely.
- Match total repetitions on both sides before increasing the load you use.
Training Notes
Run this after the main lifts, in the accessory block, at two to three sets of ten to fifteen reps per side. The pattern trains rotation and anti-rotation together, so it pairs well with pressing and hinging work. Keep the load light enough that the finish position is controlled, since the value here is in the deceleration rather than the weight lifted.
