In answer to LisaSH. I'm not really overweight, though if I lost 6 or 7 kgs I'd be happy. I'm hoping to increase my riding time now that the we are entering Autumn. It's been too hot to ride much lately (I'm a bit of a sap). High 30's and low 40's C temps do put me off somewhat.

As I said before, my legs are much stronger, but no visible shape change is evident, although they could be a trifle more toned now. I check them out in the mirror every now and then to see if they've changed. Recently changed the height of my seat and have noticed muscles complaining above the knee now. I'd been riding with the seat set in one position since I'd bought the bike and thought I'd make a change and see what happened. Am riding a medium men's Avanti hybrid/comfort bike, and it felt OK in the bike shop for my height 5'6". I'm no expert in this, just learning.

P.S. I'm new to the internet world and have only recently joined 2 cycling forums and replying to a thread is very experimental at the moment - so forgive the errors please.
