Personal Trainer

As part of my weight loss regime, I'm thinking of getting a personal trainer. I've wanted one for a while but never got round to it. They do them at my gym. I think it's about £25-30 an hour so I would probably do it once a month unil I am closer to my target weight and then amp it up to once every two weeks.
I really want to lose weight first but gradually tone up. I'll a call tomorrow and find out some details.
By the way, I didn't take my measurements down. I keep forgetting! I have to do it first thing in the morning so that it would tie up with my weight. On a good note though, I bought a pair of jeams in size 16 and they keep falling down! Hopefully I'll notice more differences soon!
