CYBEX VR2 Owner’s Manual
The Positioning
• Adjust the seat to allow the upper arm to rest on
the pad.
• Check the weight to insure that the appropriate
resistance has been selected. Body position
and control of the motion should never be
compromised by excessive weight.
• Grip the handles and rotate to the desired position.
• Sit with the spine erect and scapula retracted.
• Position the arms parallel to each other.
• Note the pivot point at the right edge of the arm
pad. Position the elbows in line with the pivot
point.
• By depressing the scapula (lowering the shoulders),
press the upper arms firmly into the pad and
elevate the elbows slightly.
The Motion
• Tighten the biceps and flex the elbows as far
as possible without raising the elbows further.
• Return to the starting position without resting and without changing the shoulder arm
position or elbow alignment.

FINISH POSITION
• Associated Muscles - The brachialis and brachioradialis are both prime movers for elbow
flexion. The brachialis is equally effective in all radioulnar positions, however, it is empha-
sized alone when pronation is maintained during elbow flexion due to the decreased effec-
tiveness of the biceps and brachioradialis in this position. The brachioradialis is emphasized
when the neutral (hammer) position is maintained.
