Seated Leg Raise form demonstration - targeted for Abs Waist workouts

Seated Leg Raise

Seated leg raises shift the emphasis toward the hip flexors more than a floor-based leg raise does, since you're working against gravity from a different angle while the torso stays upright. It's a useful option for anyone whose lower back complains during floor ab work, because the seated position takes some of the lumbar strain out of the movement. Keep the core braced so the lift comes from the hips, not momentum.

How to Do the Seated Leg Raise

  1. Sit on a flat bench with your spine upright and feet flat on the floor.
  2. Grip the sides of the bench with your hands for stability.
  3. With your legs kept straight, slowly lift them in front of you until they're level with the ground.
  4. Hold briefly at the top, then gradually bring your legs back down to start.
  5. Repeat for your desired repetitions, keeping constant tension on the working muscle throughout.

Practice and progression

Choose a short set of controlled repetitions or a manageable hold, following this movement's setup. End the set when you lose the demonstrated position. Build control before increasing repetitions, duration or resistance; holds, carries and moving drills need different prescriptions.

Technique & Form Tips

Focus on trunk flexion, rotation, or anti-movement stability as required by your specific variation. Maintain the suggested pelvic and spinal orientation to keep tension focused on the abdominal area throughout each repetition or hold.

Common Mistakes to Avoid

  • Copying the wrong trunk action: Follow the demonstrated movement. A held plank, rotation and crunch require different actions rather than the same repeated trunk curl.
  • Lower back arching: Keep the spine controlled to prevent the lower back from hyperextending under the load.
  • Excessive speed: Perform movements with deliberate control rather than relying on rapid, bouncing motions.

How to Breathe During This Exercise

Maintain a steady breathing rhythm during the effort.
