Si's bizarre pilates contraption looks suspiciously suggestive

Si & Gary 18/10/2017

Si has recently started doing pilates classes with his wife Jodi. Their instructor suggested they purchase an Oov to help with their core strength.

But what the heck is an Oov? Si brought his one into the studio to show the team first hand and give them a demonstration on how to use it. It does look slightly suggestive however...
