VARIATIONS

Bent-Knee Hip Raise

Knees bend to roughly 90 degrees

This bodyweight movement targets the lower abdominal muscles by forcing a posterior pelvic tilt. It builds core strength through a controlled hip flexion pattern without spinal loading.

HOW TO DO IT

  1. Lie flat on your back with arms resting at your sides.
  2. Bend your knees to roughly 90 degrees and lift feet slightly off the floor.
  3. Contract your abs to pull your knees toward your chest.
  4. Roll your pelvis upward until your hips clear the ground.
  5. Pause briefly at the top while squeezing your core.
  6. Lower your hips and legs slowly back to the start position.

COMMON MISTAKES

  • Swinging the legs using momentum instead of muscle control.
  • Arching the lower back off the floor during the lowering phase.
  • Straightening the knees before reaching the top contraction.

TIPS

  • Initiate the movement by tucking your tailbone, not just lifting legs.
  • Exhale sharply as you curl your hips upward.
  • Keep your lower back pressed into the floor during the descent.
