Well done, Nic. Sounds like you're well over that bad weekend now!
Daisy, I often find the gym mind-numbingly boring too and have had to use all sorts of (non-food!) tricks and bribes to keep myself on the treadmill or elliptical cross trainer (the bike and steppy are less of a problem because I can read on them). I've just joined a gym with television and radio channels on tap, which helps. And I enjoy doing the resistance machines.
Aeons ago, when I first came aboard the old forums, I posted something to the effect that the treadmill was boring, and one of the responses was a tactful version of "if it's boring, you're not pushing yourself hard enough". I think, for me, there was more than a grain of truth in that.
Cath, you definitely don't want that fellow in the gym with you. Imagine being labelled as the girl who's always with that bloke who thinks the machines are for sitting on to have a drink and a chat. I quite enjoy a gossip (ran almost a mile at 5.5mph without noticing it when one of the staff came over to chat about the GNR while I was on the treadmill) but most of the time, like you, it's head down and serious sweating.
Cheers, V-rap.
