An old gif that's been lying around for a while, so it's a bit more amateurish on the image change. Trying to upload the backlog.

   Attention all gym-goers. This is your five minute warning of the start of Women's Hour. All gym-goers should be aware we will soon begin dispersing feminising agents through the air conditioning. Anyone not wishing to take part in Women's Hour should make their way to the exits.
If you see any male gymgoers sporting headphones, or too in the zone to hear this message, kindly tap them on the shoulder and let them know.
For those staying, I hope you brought your stretchable fabrics! If not, sport bras can be purchased in our vending machines, along with swimwear for those intending to use the swimming pool and sauna. Please be aware the restriction on heavy petting still apply to the pool area... Not that anyone ever listens...
Kindly avoid using weight lifting equipment while your bodies adjust. We remind everyone that the feminising chemicals may, on semi-rare occasions, interact adversely with anabolic steroids, for anyone wishing to avoid becoming a breast-encrusted pile of quivering wombflesh.
Thank you.
