3/4 sit-up

The 3/4 sit-up is a bodyweight exercise focused on the muscles of the core. It is similar to a sit-up, but stops short of the top position. This keeps constant tension on the abs, making it more difficult than traditional sit-ups. It can be performed for time or for reps, with the feet anchored or free, as part of the ab-focused portion of any workout.

Benefits

  1. Activates and strengthens the abs, in particular the rectus abdominis or “six-pack” muscles
  2. Strengthens the hip flexors in addition to abs
  3. Simple way to progress sit-ups when they become easy to do for high reps
