Barbell Sitted Alternate Leg Raise

The barbell sitted alternate leg raise adds resistance to a seated leg raise pattern, working the abs and hip flexors as each leg extends and lifts against the bar's weight. Alternating legs keeps one side working while the other briefly rests, which changes the fatigue pattern compared to raising both legs together. Keep the core braced and avoid leaning back excessively to counterbalance the load.

How to Do the Barbell Sitted Alternate Leg Raise

1. Sit on a bench with your back straight, resting a barbell across your thighs.
2. With your legs straight, raise one leg as high as you can while keeping the other leg on the floor.
3. Lower that leg back down, then repeat with the other leg.
4. Keep alternating legs for your desired number of repetitions.

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.

Comfort and Control

Choose a load and range you can control. Stop if the movement causes pain. If discomfort persists, stop and ask a qualified professional about an appropriate exercise and range.

General guidance: Mayo Clinic on weight-training technique. Follow the specific movement steps above for this variation.
