Trunk Twist
Rotate the ribs side to side from a tall standing stance to warm the obliques and mid-back.
Overview
Trunk Twist is a standing rotation drill on Flexor. With arms out at shoulder height, the ribs and chest turn side to side while the feet stay planted.
What Trunk Twist targets
The obliques and thoracic spine create most of the rotation, with the shoulders and gaze following the turn.
Why add Trunk Twist to your routine
It is a quick way to warm the mid-back before sport, lifting, running, or any session that needs comfortable rotation.
- Standing drill with no equipment.
- Works best at a smooth, conversational pace.
- Keep the lower body quiet so the trunk does the turning.
Who it's for
Beginners, team-sport athletes, racket-sport players, and desk workers who want an easy rotational reset.
When to do it
Use early in warm-ups or between sitting blocks when you can stand and move.
Trunk Twist is a standing thoracic rotation warm-up. The feet and hips stay mostly forward while the ribs, shoulders, and gaze turn side to side in a smooth rhythm.
Setup cue
Stand with feet about hip-width apart, knees soft, and arms reaching out at shoulder height. Brace lightly through the abdomen so the pelvis stays mostly forward as the ribs begin to rotate.
Practice notes
In Flexor, Trunk Twist is typically prescribed as about 1 min per round, 1 rep, and 1 set. Adjust the dosage to what feels sustainable, breathe steadily, and ease off if anything feels sharp or unsafe.
Guidance
How to perform, tips, mistakes, safety notes, and benefits for Trunk Twist.
Follow these cues in order. Move with control and stay in a comfortable range.
- Stand with feet about hip-width apart, knees soft, and arms reaching out at shoulder height.
- Brace lightly through the abdomen so the pelvis stays mostly forward as the ribs begin to rotate.
- Turn the chest and gaze toward one side, letting the opposite arm travel across the body with control.
- Rotate back through center and toward the other side, keeping the motion smooth rather than whipping the arms.
Cues that help the movement stay smoother and more controlled.
- Rotate from the ribs and upper back while the hips stay mostly square.
- Let the head follow the chest instead of twisting the neck separately.
- Keep the knees soft so the low back does not absorb the whole twist.
Patterns to watch for so the shape stays clearer.
- Swinging the arms hard enough that momentum pulls the spine past control.
- Locking the knees and forcing rotation through the lower back.
- Letting the hips spin fully with each turn instead of warming the trunk.
Keep things comfortable and stop if something feels wrong.
- If you have a history of spinal/neck injury, disc issues, or recent surgery, consult a clinician before progressing range or intensity.
- Stop if you feel sharp pain, numbness, tingling, dizziness, or symptoms that radiate.
- Stay within a comfortable, controlled range; muscular effort or mild stretch tension should not become pain.
- Move smoothly without bouncing, jerking, or forcing the range.
Why people include this movement in their practice.
- Warms thoracic rotation before running, field sport, tennis, golf, or upper-body training.
- Coordinates obliques, ribs, shoulders, and gaze while the lower body stays grounded.
- Requires no equipment and works well as a short standing desk break.
