INCLINE TWISTING CRUNCH
Form cues
About
A decline bench crunch with a rotation at the top of each rep, alternately driving one shoulder toward the opposite knee. Targets the rectus abdominis through the crunch motion and the obliques through the twist.
Instructions
Step-by-step technique
Set Up on the Incline Bench
Hook your feet under the foot bar of an incline bench and lie back with hands lightly placed behind your neck.
Twist and Crunch to One Side
Flex your waist and twist your torso to bring one elbow toward the opposite knee. Squeeze the oblique at the top.
Lower and Alternate Sides
Lower yourself back until your shoulder blades contact the bench. Immediately twist to the other side on the next rep. Continue alternating for the desired reps.
Common mistakes
What goes wrong — and why
Rotating arms across the body instead of the torso
Moving only the arms creates the illusion of rotation without engaging the obliques.
Drive the rotation from the shoulder and torso; the elbow should reach toward the opposite knee via trunk rotation.
Pulling on the neck with clasped hands
Neck pulling strains the cervical spine and removes abdominal work.
Hands behind the temples only; never interlock and pull — the abs must do the work.
Going too fast to generate reps
Speed-based reps sacrifice the oblique contraction quality.
Take 1 second to rotate to the contracted position and hold briefly before lowering for 2 seconds.

Adaptations for every level
Flat Floor Twisting Crunch
Perform the rotating crunch on the floor without the decline angle to learn the movement pattern.
Incline Twisting Sit-Up
Extend the range to a full sit-up with rotation for greater rectus abdominis and oblique demand.
Weighted Incline Twisting Crunch
Hold a weight plate or medicine ball at the chest while adding the twist for progressive overload.
