The Oblique Sit-Up is a bodyweight exercise that targets the oblique muscles on the sides of the abdomen while engaging the rectus abdominis and transverse abdominis for core stability. Performed by lying on your back with knees bent, one hand behind the head, and twisting the torso to bring the elbow toward the opposite knee during the sit-up, it builds rotational strength and enhances waist definition. Ideal for athletes, fitness enthusiasts, or anyone seeking to improve core power and oblique development without equipment.
How to Perform Oblique Sit-Up
- 1Lie on your back on the floor with knees bent and feet flat on the ground, hip-width apart.
- 2Place your left hand behind your head, elbow flared out, and right hand on your right thigh.
- 3Engage your core by pulling your belly button toward your spine.
- 4Exhale as you curl your upper body up, twisting your torso to bring left elbow toward right knee while sliding right hand up your thigh.
- 5Inhale as you slowly lower your upper body back to the starting position.
- 6Repeat for desired reps, then switch sides (right hand behind head, left hand on left thigh).
- 7Key form tips: Keep movement controlled—avoid jerking or pulling with your neck. Focus twist on obliques, not momentum. Common mistakes: Arching lower back or letting feet lift off ground.
