Step by step instructions, muscle activation and variants for the Lying Elbow-to-Knee Crunch.
The Lying Elbow to Knee is a bodyweight core exercise performed on the floor that crunches the opposite elbow toward the knee in a twisting motion, targeting the abs and obliques. It combines spinal flexion with rotation to train both the rectus abdominis and the lateral core muscles effectively.
The Lying Elbow-to-Knee Crunch is a foundational movement that builds strength and muscle through controlled, progressive overload. Train it 1 to 2 times per week with 3 to 5 working sets per session, gradually adding weight or reps as form holds up.
