Thank you for your feedback!
The Twisting Crunch is a floor-based exercise where you lift your upper body while rotating toward one knee. By combining a crunch with a controlled twist, it challenges the core more than a straight-up crunch and helps build strength through rotation.
You should feel the effort mainly in the front and sides of your core. Focus on smooth movement, keeping your lower back lightly pressed into the floor and your neck relaxed. Rotate from your torso rather than pulling with your arms, and control both the lift and the return.
This exercise fits well into core workouts, circuits, or conditioning sessions. To make it easier, reduce the range of motion or keep both feet on the floor; to make it harder, slow the tempo or pause briefly at the top of each twist.
How to Perform the Twisting Crunch
- Lie on your back with knees bent and feet flat on the floor, placing your hands lightly behind your head with elbows flared out.
- Draw your navel toward your spine to engage your core, ensuring your lower back maintains contact with the floor throughout the movement.
- Exhale as you lift your shoulders and upper back off the floor, keeping your neck neutral by maintaining space between your chin and chest.
- As you curl upward, rotate your torso by bringing your right elbow toward your left knee while extending your right leg.
- Hold the contracted position for a brief moment, focusing on the oblique muscles working during the twist.
- Inhale as you slowly lower your upper body back down, controlling the descent without fully relaxing at the bottom.
- Repeat the movement on the opposite side, bringing your left elbow toward your right knee while extending your left leg.
- Continue alternating sides with a controlled tempo, avoiding momentum and keeping your movements deliberate and precise.
Important information
- Keep your elbows wide throughout the movement to prevent neck strain and maintain proper form.
- Focus on the rotation coming from your core rather than simply moving your elbows toward your knees.
- If you feel any neck discomfort, try placing your tongue on the roof of your mouth to help stabilize neck muscles.
- Make sure your breathing remains consistent and coordinated with each phase of the movement.
FAQ - Twisting Crunch
Twisting Crunches primarily target the obliques (side abdominal muscles) while also engaging the rectus abdominis (six-pack muscles). The rotational component specifically activates the internal and external obliques more effectively than standard crunches.
Beginners can perform the movement with a smaller range of motion and no added resistance. For a greater challenge, advanced lifters can hold a weight plate or medicine ball against the chest, increase the rotation angle, or elevate the feet off the ground.
The most common mistakes include pulling on the neck, rushing through repetitions, and rotating from the neck rather than the torso. Focus on initiating the twist from your core, keeping your neck in a neutral position, and controlling the movement throughout the entire range of motion.
For optimal results, perform 2-3 sets of 12-15 controlled repetitions on each side, 2-3 times weekly. Quality always trumps quantity with this exercise—focus on proper form and complete muscle engagement rather than high rep counts.
Twisting Crunches may not be suitable for those with existing lower back conditions due to the rotational stress. If you have back issues, consult a healthcare provider first and consider starting with stabilization exercises like planks before progressing to rotational movements.
