This high-intensity standing variation of the bicycle crunch targets the obliques and hip flexors while providing a significant cardiovascular challenge. It improves rotational core strength and coordination by combining a knee-to-elbow crunch with a rhythmic, jumping-jack-style tempo.

Setup

  1. Stand with your feet shoulder-width apart and your knees slightly bent.
  2. Place your fingertips lightly behind your ears with your elbows flared out wide to the sides.
  3. Engage your core by drawing your navel toward your spine to establish a stable base.

How to do it

  1. Drive your right knee up toward your chest while simultaneously rotating your torso to bring your left elbow toward the rising knee.
  2. Exhale sharply at the peak of the movement, focusing on the contraction in your obliques.
  3. Return to the starting position and immediately repeat the movement on the opposite side in a fluid, alternating 'cycling' motion.
  4. Maintain a fast, rhythmic tempo, staying light on the balls of your feet throughout the set.

Form checklist

  • Keep your chest upright and avoid pulling your head forward with your hands.
  • Ensure the rotation comes from your midsection rather than just moving your arms.
  • Drive the knee as high as possible to fully engage the lower abdominals and hip flexors.
  • Maintain a slight bend in the standing leg to absorb impact and improve balance.

Pro tips

  • Focus on the 'rib-to-hip' connection; imagine wringing out your torso like a towel at the top of every rep.
  • Keep your elbows pinned back to force your obliques to do the work of rotating the ribcage.

Make it harder

  • Add a small hop on the standing leg as you crunch to turn the movement into a plyometric exercise.
  • Increase the speed of the transitions while maintaining a full range of motion for maximum metabolic demand.
