Muscle Groups: Bend Forward - Rectus Abdominis, Internal and External Obliques (both sides of obliques contracting together) Extend Backwards - Erector Spinae.

Reminders:

• Allow the trunk to do the movement, do not push down or pull up with the arms.
• You want to use the arm rests provided to you but only to be used as a contact point. As you pull down with the abs the arm rests will get in the way allowing us to connect the abdominal muscles to the resistance.
• Lengthen the spine before extending the back on the motion up.
• Exhale on the way down on this particular piece of equipment, as doing so will allow you to get a tighter contraction on the abdominal muscles.
• Inhale on the way up on this particular piece of equipment, as diong so will help extend the spine during this particular part of the exercise.
