How to do the TRX Oblique Crunch

  1. Attach suspension straps to a secure high anchor point. Adjust them to hang about a foot off the ground.

  2. Place your feet in the straps and position yourself in a suspended plank position with your hands on the ground, directly under your shoulders.

  3. Ensure your body is in a straight line from head to heels, actively engaging your core.

  4. While keeping your upper body stable, draw your knees towards your right elbow, rotating your hips and flexing the abs as you bring your knees up.

  5. Reverse the motion, extending your legs back to the plank position.

  6. Without pausing, now draw your knees towards your left elbow, again rotating your hips for the twist.

  7. Extend back to the plank position to complete one repetition.

  8. Continue alternating sides for the desired number of repetitions.

Make sure to perform the exercise in a controlled manner, focusing on twisting with your core rather than using momentum. Keep regular breathing throughout the exercise and maintain a neutral spine to avoid any lower back strain.
