A crunch variation that targets the obliques by rotating the shoulder toward the opposite knee, building rotational core strength and lateral trunk stability.
Form tips
Cross your arms over your chest or place your fingertips lightly behind your ears — never pull on your neck.
Rotate your shoulder toward the opposite knee, not your elbow — this ensures spinal rotation rather than just elbow movement.
Complete all reps on one side before switching to maintain focused oblique tension.
