Exercise and I have a stormy relationship.
I too have joined the gym many times and many times I went a couple of rounds then gave up and piddled my money away on the wasted membership.
I am really proud of you Delia... I wish I had the stick-to-itness to see it through but alas I know myself better. Now when the whim takes me I go as a casual visitor...much cheaper for me in the long run as it usually pans out to 3 visits.
Oddly when I go I quite enjoy it... I have issues I think. We have 3 gyms in this town.. an aquatic center based one... a proper beef it up type gym in its own complex and an any time gym which doesnt do the classes but only has the machines ( which I have at home and dont use)
I have a 12 meter pool, a walker and an eliptial machine as well as a a 3 1/2 k rural estate to walk around and I still do nothing...
As you can see I am bone lazy... I call it old but its really just laziness.
