Abs, Obliques

A crunch variation that adds rotation, targeting the obliques alongside the front abs for a more complete core workout.

How to do it

  1. Lie on your back with your knees bent and hands lightly behind your head.
  2. Curl your torso up and rotate, bringing one elbow toward the opposite knee.
  3. Lower back down under control.
  4. Repeat on the other side, alternating with each rep.
  5. Keep the movement controlled rather than fast and jerky.

Coaching tips

  • Focus on rotating through your torso, not just pulling with your elbow.
  • Keep your lower back gently pressed into the floor throughout.
  • Quality over speed — slow, controlled twists work the obliques far better than fast ones.

Common mistakes

  • Pulling on the neck with the hands instead of rotating through the core.
  • Moving too fast, which relies on momentum instead of oblique engagement.

Frequently asked questions

Do twisting crunches make your waist smaller?

No exercise spot-reduces fat around the waist — twisting crunches build oblique muscle, but visible definition depends on overall body fat.
