How to Perform the Leg Raise

  1. Lie flat on your back on a mat or bench with your legs fully extended and arms at your sides or tucked under your hips for support.
  2. Press your lower back firmly into the floor to engage your core from the start.
  3. Keeping your legs straight and together, slowly raise them upward by contracting your abdominals.
  4. Continue lifting until your legs are perpendicular to the floor or as high as you can go while keeping your lower back pressed down.
  5. Pause briefly at the top, squeezing your abs.
  6. Lower your legs back down slowly and under control, stopping just before your feet touch the floor.
  7. Maintain constant tension in your abdominals throughout the entire range of motion.
  8. Repeat for the prescribed number of repetitions.

Common Mistakes to Avoid

Allowing the lower back to arch off the floor

Press your lower back into the ground throughout the movement; if it lifts, reduce the range of motion or bend your knees slightly.

Using momentum to swing the legs up

Move slowly and deliberately, taking 2-3 seconds on both the lifting and lowering phases.

Dropping the legs too quickly on the way down

Control the eccentric portion; the lowering phase is where much of the core strengthening occurs.

Muscles Worked

Benefits

  • Effectively targets the lower abdominals, which are often underdeveloped in many trainees.
  • Requires no equipment and can be performed anywhere.
  • Strengthens the hip flexors, which are important for athletic performance and posture.

Pro Tips

  • Place your hands under your glutes or grip a bench behind your head for extra lower back support.
  • To increase difficulty, hold a light dumbbell between your feet or add ankle weights.
  • If straight legs are too challenging, bend your knees slightly to reduce the lever arm.
