• Grasp the Hand Grips in both
hands, drawing them over
your shoulders. Rest the back
of your fists on your chest or

flat or in a normal arch,

ribs toward your hips. Move as
far as you can without moving

Success Tips
• Lift your chest, keep your knees bent
and feet on Platform.

rather than lead it. Maintain normal
neck posture.
• Tighten your abs throughout the
entire exercise, relaxing only at the
end of each set.
• Move slowly to eliminate
momentum.
• Allow exhalation up and inhalation
down without exaggerating
breathing.
