A hell of an exercise when done properly but so much to gain from it.
Transfers to:
- overhead pressing movement
- handstand
Execution:
Lie down grabbing a stick on shoulder width (arms parallell to each other)
Tense the body by applying the following cues:
Tense the midline:
- Posterior Pelvic tilt: squeeze the butt as much that the lower back flattens out
- Bracing the abs: Decrease the distance formed by the lower part of the ribcage & the pelvis
Only when the midline is active & stays active you open the shoulder angle
- Glenohumeral Exorotation: "Try" to turn the thumbs to the ceiling (while grabbing the stick the thumbs won't be able to turn, but the shoulder will)
- Glenohumeral Abduction: pull the hands out of each other
- Scapular Elevation: press the hands away from the body (parallell to the body)
Only when the shoulder is in position you retract the scapulae
- Scapular Retraction: pull the stick to the ceiling
In Full position your body should be flattened out like a line, hence the name body line drill
When you're going past the line up then they're a few things that should be checked:
- are you arching the back? Check the midline!
- are you taking the stick on shoulder width?
- are you dislocating the shoulder? Don't! push the shoulders away, pull apart and then retract (avoid the dislocation)
Don't get me wrong, I'm not claiming these are faulty movements. They're rather not suitable in the context of creating a body line handstand or an overhead motion without arching the lower back.
