What it is

This bodyweight exercise strengthens your abdominal muscles by engaging your core. You lie on a flat bench or mat, extending your legs, then pull your knees towards your chest. It's a compound movement that effectively targets your rectus abdominis. Maintain controlled motion throughout the exercise.

Technique tips

  • Place hands under your glutes or grip the bench for stability.
  • Exhale as you pull your knees in, inhale as you extend.
  • Pull your knees as close to your chest as comfortably possible.
  • Avoid swinging your legs; use slow, controlled movements.
  • Keep your lower back pressed to the bench or mat.
  • Fully extend your legs without touching the ground to maintain tension.

How to track your progress

Log reps, and add the extra load if you wear a belt or a vest. Straddly counts your bodyweight in the estimated max, so added weight and extra reps both show up as progress, and new records are flagged during the session.
