Dh is the typical office worker/couch potato. Sitting at desk all day and in front of TV/PC all night.
He gets up at 6.45, leaves for work at 7.30 - long commute which requires car. Gets home at 6, we eat as a family, he spends some time with dd's, then when dd's in bed he chills out - by then it's about 7.30. Sure, he could go out to do some exercise then - but who has the energy/motivation? At weekends we like to be together as a family - we do go for walks, but they're not really exercise with a two and a four year old in tow!
So when do people fit it in???
(Btw dh is very slim so he feels justified in not doing any exercise.)
