Weighted Hanging Straight Leg Raise

  • Advanced
  • Compound
  • Rep-based
  • Upper legs
  • Waist

This advanced core exercise targets the lower abdominals and hip flexors by adding external resistance to a hanging leg raise, significantly increasing the demand on the rectus abdominis. It builds exceptional core strength and stability while improving grip and shoulder endurance.

Muscles worked

Primary

  • Obliques

Secondary

  • Deltoids
  • Erector spinae
  • Lats

Equipment

  • Dumbbell

Setup

  1. Place a dumbbell on the floor directly beneath the pull-up bar.
  2. Grip the bar with an overhand, shoulder-width grip and hang with arms fully extended.
  3. Secure the dumbbell between your feet, squeezing your ankles together to lock it in place.
  4. Engage your lats and core to stabilize your body and prevent swinging.

How to do it

  1. Exhale as you lift your legs straight out in front of you, keeping knees locked and the dumbbell secure.
  2. Continue the movement until your legs are at least parallel to the floor, focusing on tilting the pelvis upward.
  3. Inhale as you slowly lower your legs back to the starting position with a controlled 3-second tempo.
  4. Maintain a slight hollow-body position at the bottom to keep tension on the abs and prevent momentum.

Form checklist

  • Keep legs completely straight throughout the entire range of motion.
  • Avoid using momentum or swinging your torso to lift the weight.
  • Squeeze the dumbbell tightly with your feet to prevent it from slipping.
  • Keep your shoulders 'packed' by pulling them away from your ears to protect the joints.

Pro tips

  • At the top of the rep, focus on curling your pelvis toward your chest to maximize rectus abdominis contraction.
  • Use lifting straps if your grip strength limits your ability to complete the set for your core.
  • Visualize pulling your belly button toward your spine to engage the deep transverse abdominis.

Make it harder

  • Increase the eccentric phase to 5 seconds to maximize time under tension.
  • Perform 'Toes to Bar' by lifting the dumbbell all the way to the pull-up bar while maintaining straight legs.
