I now have a membership. It costs me £15 a month, and I can go as much as I want. The gym is open 24 hours a day, and every day except Christmas and New Year. I feel this is some of the best moolah I've ever invested in myself.
Any kind of mood I'm in, any time of day or night, I can go and row for half and hour/an hour and change my mood for the better.
I'm heading over to another part of the forum. I think I feel like I'm not much of a newcomer any more.
