A gymball has to offer a fine balance between support and instability, if the ball is too rigid or too soft then the effects
on your core stabilising muscle will be compromised. The Reebok gymballs all perform to these optimal levels even
if you are simply using the ball to sit on at a desk or performing dynamic exercises.
Using the right size ball is important, some people seem to think bigger is better but actually the correct size of ball
is based on your height because when lying down this effects the position of your back and pelvis. If you are less
than 175cm tall (5 feet 8 inches) then go for a 55cm ball. 176 – 195cm (5 feet 8 inches to 6 feet 3 inches) then you
need a 65cm and if you are 196cm (6 feet 4 inches) or more then you need the 75cm. If you are going to use the
ball for sitting at a desk (which is a fantastic idea) then you can go for a ball one size smaller so that you don't have
pressure on the back of your legs when sitting on the ball.
The materials that we use to make our gymballs are a very high quality and will give you the best performance if you
follow this advice. When you blow the ball up for the first time only blow it up to 80% of the correct size then leave it
overnight to allow the fibres to 'stabilise' then add the remaining 20% the next day. This will make the surface of the
ball smooth and most stable.
Did you know?.. All Reebok gymballs are anti- burst, now that does not mean you can stab it or kick it around. No,
what it actually means is if you were unfortunate to get a puncture in the ball whilst you were using it instead of
going 'pop' like a ballon it deflates slowly to avoid the risk of injury.
