Kneeling takes your legs out of the movement, so the band anchored at waist height behind you loads a pure trunk twist toward the opposite hip. Compared with the standing oblique version, there is less sway to leak force through, which makes it easier to feel the obliques doing the rotation rather than your hips.
How to do the Banded Kneeling Oblique Crunch
- Attach the band to a sturdy anchor point at waist height.
- Kneel down facing away from the anchor point and hold the band with both hands, keeping your elbows bent and close to your sides.
- Engage your abs and slowly twist your torso to one side, bringing your hands towards your opposite hip.
- Pause for a moment, then slowly return to the starting position.
- Repeat on the other side.
- Continue alternating sides for the desired number of repetitions.
Tip: Breathe out as you crunch and let the last bit of air leave the lungs at the top of each rep.
Muscles worked
Primary
Abs · Core
The rectus abdominis shortens to bend the spine forward, and each rep should end with the upper abs fully contracted and the ribs pulled down.
Secondary
- Obliques — Twisting or side crunch variations bring the obliques in, and you should feel them along the side of the waist on the working side.
Common mistakes
- Pulling on the neck — hands behind the head should support, not yank; keep the elbows wide and the chin about a fist away from the chest.
- Sitting all the way up — a crunch is a curl of the ribs toward the pelvis, not a sit-up; the lower back should stay on the floor the whole time.
- Cranking out fast reps — momentum does the work if you bounce; lift to a squeeze, hold for a count and lower slowly.
- Never adding load — once bodyweight reps get easy, hold a plate on the chest or use a cable rather than doing sets of 50.
Where it fits in a workout
Crunches close out a session after the heavy work, or they can fill the rest periods between sets of a lift that does not need much bracing. Pair a cable crunch with a cable side bend on the same stack.
How many sets, how heavy and how hard: see what the ACSM position stands support.
