Congratulations and thank you for your purchase of Core-Tex Sit!
Please take the time to review all enclosed materials to maximize the benefits and safety associated with
the Core-Tex Sit.
Movement is life and the Core-Tex Sit is an exercise device that can help keep us healthy doing
something most people do for up to 10 hours a day! Your Core-Tex Sit allows for a controlled, dynamic
sitting experience that provides benefits to the lower back, hips, core and pelvic floor.
The patented design allows the Core-Tex Sit to tilt, slide and rotate all at the same time and at just the
right amount. Core-Tex Sit is designed to be sensitive and responsive to any subtle weight shifts of your
body once you are sitting on it. Its motion and how far the top can move is limited by an internal
stopper. As soon as your buttocks make contact your Core-Tex Sit, your body will immediately need to
engage your muscles to control the motion.

•burn calories while working at the computer
Step 1
Choose your chair. The ideal seated surface for your Core-Tex Sit is on a flat, firm chair with slight
padding or no padding at all. Sloped, contoured or very soft, deep cushioning on the chair will interfere
with motion of your Core-Tex Sit. Larger individuals will find chairs with minimal to no padding to
work best. If using with a swivel chair and/or a chair on wheels, it is recommended that you lock the
chair and wheels so that the chairs motion does not counter the motion of Core-Tex Sit.

Step 2
Center your Core-Tex Sit. Place your Core-Tex Sit directly in the center of your chair and away from
the edges.
Step 3
Center the top. Use your hand on the foam top to bring the top as close to center as possible before you
sit. As you sit, hold the top place until your buttocks comes in contact with it. Center your “sit bones”
on either side of the peak of the top. The sit bones are the bones under each of your buttocks. The
center of the logo should now be in the center of your hips and
buttocks. This will allow for equal movement in all directions.
Never grab the underside of the padded section of your Core-Tex Sit
when sitting. Keep fingers and clothing clear of the space between
the top and bottom sections.

Step 4
Sit with feet flat on the floor or feet on a stool as needed. Your foot contact with the ground or stool will
provide the needed foundation to safely and effectively engage the muscles of the hips, abdominals and
lower back.
How to use your Core-Tex Sit:
1. Unconsciously reacting to movement of Core-Tex Sit while you are engaging other parts of your
body. For example, as you work at your desk and reach for your phone, your body’s center of
gravity shifts slightly. Core-Tex Sit will move, and your body will need to engage to react and
control the motion without you having to think about it.
2. Purposefully moving Core-Tex Sit in directions you desire. You decide how you want Core-Tex
Sit to move by controlling which direction it moves.

3. Use your Core-Tex Sit for as little as a few minutes per day or up to 30:00 increments while
working. If your buttocks gets tired from the sitting surface, simply remove from your chair and
use again later when ready.
Start with our FOUNDATIONAL FIVE:
a. Front to back
b. Side to side
c. Diagonals
d. Circles
e. Spinning
The analogy of sitting in the center of a clock can be helpful. With the FOUNDATIONAL FIVE,
always keep your torso tall and still with your head over your shoulders. Movement of your body
should occur from the bottom of your ribs (midsection) to your hips. Avoid tilting the torso in response
to motion of Core-Tex Sit.

Front to Back-tilt the front down toward 12 o’clock, creating a backward pelvic tilt and flattening the
lower back. Tilt the back down toward 6 o’clock causing a backward pelvic tilt and arch in the lower
back. Move continuously back and forth for the desired repetitions.
www.coretexfitness.com/sit ©2020 Reactive Training, LLC
Side to side-tilt the left side down toward 9 o’clock, causing your right hip to raise and creating a side
bend of your body to the right. Tilt the right side down toward 3 o’clock, causing your left hip to raise
and a side bend of your body to the left. Move continuously back and forth for the desired repetitions.
www.coretexfitness.com/sit ©2020 Reactive Training, LLC
Diagonals-tilt the back to left to 8 o’clock then right front toward 2 o’clock. Move continuously back
and forth for the desired repetitions. After the desired repetitions, move from 10 o’clock to 4 o’clock.
Move continuously back and forth for the desired repetitions.

Circles-use the top of Core-Tex Sit to create a full circle around the base as if you were touching every
number on the clock. Move your hips like a hula dancer. First move in a clockwise direction for the
desired repetitions and then repeat in a counter-clockwise direction for the same repetitions.
www.coretexfitness.com/sit ©2020 Reactive Training, LLC
Spinning-with your feet pointing straight ahead and your head and shoulder pointing straight, spin
Core-Tex Sit back and forth from left to right by shifting knees side to side. Do your best to keep your
shoulders and head facing forward. Move continuously back and forth for the desired repetitions.
