Instructions
Preparation
- Grasp cable stirrup from hip height pulley. Turn body away
from pulley. Position elbow of loaded arm out to side, lower
chest height. Position loaded hand back approximately shoulder
height and elbow width. Step far forward with foot of opposite
side of loaded arm. Bend knees and position heel off rear foot
off floor.
Execution
- Push stirrups foward and upward at 30º to 45º until
arm is straight and inline with cable. Return stirrup to original
position until slight stretch is felt in chest or shoulder. Repeat.
Continue with opposite arm.
Comments
- Stirrup should follow slight arch pattern, in front/above
of upper arm between elbow and chest in stretched position, travelling
inward in front/above shoulder at contracted position.
-
- In standing position, both spinal rotation and hip rotation
contribute to body's rotation. Because rear leg is only supported
by forefoot, hip of forward leg is utilized (hip internal
rotation / transverse
adduction) much greater than hip of rear leg since forward
leg offers more secure base of support.
-
- The effective range of motion of Pectoralis Major is only
about half of what it is in bilateral
non-twisting movement.
