Twist And Leg Lift

  • Intermediate
  • Compound
  • Timed hold
  • Shoulders
  • Waist

A dynamic standing core exercise that integrates rotational power with hip flexion to strengthen the obliques, abs, and quadriceps while improving balance. It effectively engages the upper body stabilizers and lower body through a functional, multi-joint movement.

Setup

  1. Stand with your feet hip-width apart and your core engaged.
  2. Place your hands lightly behind your head with elbows flared out (prisoner style) or hold your arms bent at 90 degrees in front of your chest.
  3. Maintain a tall posture with your shoulders pulled back and your gaze forward.

How to do it

  1. Exhale as you lift your right knee toward your chest while simultaneously rotating your torso to bring your left elbow toward that knee.
  2. Focus on 'crunching' your obliques to bring the elbow and knee toward each other, meeting near the midline of your body.
  3. Inhale as you return your foot to the floor and rotate your torso back to the center with a controlled tempo.
  4. Repeat the movement on the opposite side, alternating legs for the duration of the set.

Form checklist

  • Keep your chest lifted and avoid pulling on your neck with your hands.
  • Drive the knee up high using your lower abs rather than just swinging the leg.
  • Maintain a slight bend in the standing leg to improve balance and stability.
  • Ensure the rotation occurs at the waist and mid-back, not just moving the elbows.

Pro tips

  • Imagine wringing out a towel at your waist to maximize oblique engagement during the peak of the twist.
  • Squeeze the glute of your standing leg to create a stable anchor for the rotational movement.
  • Pause for one second at the top of the lift to emphasize the mind-muscle connection with the abdominal wall.

Make it harder

  • Perform the movement with a slow 3-second lowering phase to increase time under tension for the hip flexors and core.
  • Hold a light medicine ball or dumbbell between both hands to increase rotational resistance and shoulder activation.
