Are you lazy or allergic to exercise? It turns out your parents may be to blame.
According to ASAP Science, gymaphobics may have inherited the 'couch potato' gene from their parents.
This means they are genetically programmed to cower at the thought of activity. Gee, thanks mum and dad!
On the flip side, those spritely types who bounce around the office and love going to the gym may have got their energy sources from their own, active, parents - damn them!
