Description
Powercore Exercise Balls are professional grade Anti-Burst, and have a maximum user weight of 150kg. Our Exercise Balls are made from stronger materials which prevent them from popping or slipping.
NB* How to inflate an exercise ball:
Blow it up until its rock hard (preferably with a petrol station air pump), let it stretch (it needs to stretch!) and then blow up again until you get to recommended size. This may take a few days. DO NOT OVER INFLATE.
There are some possibilities to cause the ball burst:
1) Load weight more than 150kg
2) Ball is inflated too big (much more than its specified size)
3) Ball too old, more than one year usage
