I've just started doing some classes at the gym and am having terrible trouble with my trousers, which rather classily keep sliding down my arse.
They are some m&s Capri style ones, fit very well - they feel a bit snug round my waist - but once we get going, they start sliding and I'm hitching them up constantly.
I thought initially it was my knickers as I was wearing a pair of satiny material ones, so tonight wore the big cotton pants, but exactly the same result.
No-one else seems to have this problem - what am i doing wrong? Or recommendations of stay up gym kit?
