About this exercise

The Side-Lying Cycle Oblique Tuck is a floor exercise performed on the side where you cycle the knees in toward the chest in a tucking motion, placing intense tension on the obliques with each repetition. The side-lying position isolates the lateral core effectively without stressing the lower back.

How to Perform

  • Lie on your side with your body in a straight line, legs extended and stacked
  • Support your head with your bottom arm or rest it on the floor
  • Engage your obliques and draw both knees up toward your chest in a tucking motion
  • Extend the legs back out without letting them touch the floor
  • Continue cycling the knees in and out for the desired reps
  • Keep your hips stacked and avoid rolling backward during the movement
  • Complete all reps on one side before switching
