Exercise
WEIGHTED INCLINE TWISTING CRUNCH (ARMS CROSSED)
Form cues
About
A loaded incline crunch adding trunk rotation with arms crossed on a weight plate, training both the rectus abdominis and obliques under progressive resistance.
Instructions
Step-by-step technique
Secure body and load weight
Hook your feet firmly under the bench pads and lie back on the incline surface. Hold a weight plate tightly against your upper chest by crossing your arms over the weight to ensure it remains stable throughout the entire range of motion.
Keep plate flush against chestInitiate the crunch movement
Engage your core to lift your upper torso off the bench while keeping your lower back pressed firmly against the padding. Focus on using your abdominal muscles to generate the upward force rather than pulling with your neck or shoulders.
Control the upward phasePerform the trunk rotation
As you rise, simultaneously rotate your torso toward one knee to target the obliques. Ensure the movement is a clean, intentional twist rather than just leaning to the side, maintaining tension in your midsection throughout the rotation.
Lead with the shoulderLower back with control
Slowly reverse the rotation and lower your upper back toward the bench under complete control. Do not let your torso crash back down, as maintaining a slow, eccentric tempo maximizes the time under tension for your core musculature.
Resist gravity on descentAlternate sides each repetition
Perform the next repetition by rising and rotating toward the opposite knee to ensure balanced development of the obliques. Continue alternating sides until you have completed all prescribed repetitions for your set, focusing on consistent form.
Maintain rhythmic breathingCommon mistakes
What goes wrong — and why
Rotating only the shoulder
Moving just the shoulder blade rather than rotating the trunk reduces oblique activation.
Rotate from the mid-back, driving the shoulder toward the opposite knee.
Losing control of the plate
A shifting plate destabilizes the movement.
Hold the plate firmly against the chest throughout the twist.
Alternating sides inconsistently
Favoring one side creates asymmetrical development.
Perform equal reps to each side and track both sides per set.

Incline Twisting Crunch (bodyweight)
Perform without added weight to learn the rotational crunch pattern.
Bicycle Crunch
A floor-based alternating rotation crunch for high oblique activation.
Weighted Decline Twisting Crunch
Use a decline bench for greater range of motion under loaded rotation.
