I used to go to curves which is a womens only thing, not quite a gym-you do 30mins 3 times a week (or more) doing 30secs on a resistance machine and then 30 secs jogging on the spot, moving round in a circle. It doesnt sound like much but I got really good results-massive inch loss! then was struck down with glandular fever and couldnt go and by the time I was well enough to exercise again it had shut down! Gutted! Although if I remember it was quite expensive-£30 per month which then you would need to pay for swimming on top of that
My local leisure centre is £28per month which includes the gym any classes and swimming pool. They do not allow kids in the pool after 9pm and it is pure bliss! I went this morn and spent most of the time trying to find somewhere to swim around them-sticking to nights from now on!
