1. Feet positioned so that the thighs are
roughly parallel to the floor. The feet
should always be maintained securely
in position for the maximum strength
measurement.
2. Roller: Roller pad at chest height
(should not constrain the chin when
curling forwards).
Starting position
Upper body leaning all the way back.
The roller pad should be resting lightly
on the chest.
Finishing position
Upper body curled as far forward as
possible.
Exercise description
Keep the arms bent in front of the
roller. During the curling movement,
use the abdominal muscles to curl
one vertebra at a time. Repeat the
process when extending backwards
again.
Please note:
People with back problems should res-
trict the range of motion and keep the
feet relaxed.
