SPRI Xerdisc User manual

Xerdisc™
Inflation Tips
• Use a bicycle pump and ball needle to inate
the Xerdisc.
• To determine the optimal degree of ination simply
inate to the point at which the at-side surface of
the Xerdisc is parallel to the oor
when hand-pressure is applied. Slightly under
inate or over inate to create an increased
balance challenge.
• Never over-inate creating a rigid, dome-top
surface.
IMPORTANT!
Please read the instructions below before using
the Xerdisc.
• Always use the Xerdisc with spiked-side down.
• Do not place the Xerdisc on slick or slippery
surfaces. Avoid sharp objects and surfaces.
• Avoid bouncing or jumping on the Xerdisc.
• Be sure to check the Xerdisc for proper ination
before each use (refer to “Ination Tips”). Avoid
over-ination of the Xerdisc.
• Always perform general warm-up activities
prior to performing Xerdisc exercises.
• Perform only the exercises as shown in this chart
or other SPRI produced informational resources.
• Mimic all exercises without the Xerdisc until
prociency is achieved with each exercise.
• Perform an equal number of exercise repetitions
with each arm/leg to avoid development of muscular
imbalances.
• Wear appropriate footwear while using the Xerdisc.
• Make sure bottom of foot (feet) is in full contact with
top of the Xerdisc at all times.
• If necessary, place hand on wall or back of chair for
added support while performing Xerdisc exercises.
• Perform exercises in a slow and controlled manner.
• Keep abdominal muscles tight while performing
exercises.
• Avoid straining or holding your breath while
exercising.
• Discontinue any exercise that is uncomfortable
or causes discomfort.
• Consult your physician before beginning any type
of exercise program.

exercise selected.
• Rest approximately 30–60 seconds between each
exercise set.

full range of motion.

a full range of motion, increase rest time between
exercise sets or eliminate the use of the Xerdisc for a
period of time.
