CYBEX VR2 Owner’s Manual
The Erector Spinae
• Spinal Extension - The erector spinae are respon-
sible for extension and stabilization of the spine.
• Range of Motion - Motion of the spine is elimi-
nated in this exercise. The goal is to maintain
proper spinal alignment with the erector spinae
during resisted hip extension. This is identical to
the proper functional lifting motor pattern required
in daily activity. Hip motion should be limited to
that which can be performed with proper spinal
alignment.
• Associated Muscles - The gluteus maximus and
hamstrings are responsible for hip extension. The
hamstrings will be involved to a lesser degree due
to the position of slight knee flexion.
