Seated Lower Trunk Lateral Flexor Stretch

Perform the Seated Lower Trunk Lateral Flexor Stretch to improve flexibility in your lower back and lateral trunk muscles.

  1. Sit on the floor with your legs extended in front of you.
  2. Bend your right knee and place your right foot on the outside of your left knee.

How to perform the Seated Lower Trunk Lateral Flexor Stretch

  1. Set up. Set up in a stable, balanced starting position appropriate for the Seated Lower Trunk Lateral Flexor Stretch using your body weight.
  2. Brace and execute. Brace your core, control the descent, and move through a full pain-free range of motion while emphasizing your abdominals.
  3. Reset. Reverse the movement under control and reset between repetitions, keeping your form crisp on every rep.

Coaching cues

  • Move with intent — every rep should feel deliberate, not rushed.
  • Drive force through your abdominals rather than momentum.
  • Keep your breathing steady: exhale on the hard part, inhale on the reset.

Common mistakes

  • Using too much weight and losing positional control.
  • Cutting the range of motion short and missing the target muscle.
  • Letting your spine round or hyperextend instead of staying neutral.
