Tracks
Reps only

Works

  • Abdominals
  • Obliques

How to do it

  1. Lie flat on your back with knees bent and feet on the floor.
  2. Place your hands lightly behind your head without pulling on your neck.
  3. Lift your right shoulder toward your left knee while twisting your torso.
  4. Lower back to the start position with control.
  5. Repeat the motion on the opposite side, bringing left shoulder to right knee.

Common mistakes

  • Pulling on the neck with interlocked fingers.
  • Rushing the movement and using momentum instead of muscle.
  • Lifting the hips off the floor rather than curling the spine.

Tips

  • Exhale sharply as you twist to maximize abdominal contraction.
  • Keep your lower back pressed firmly into the floor throughout the set.
  • Initiate the twist from your ribcage, not just your arms.
