When giving all this advise about going to the gym, swimming, tai chi, pilates, yoga etc does anyone from the powers that be factor in the cost i wonder. I play bowls a couple of times a week and go to a knitting group this costs me 10.00 per week for these things, 40.00 per month. When you are on a limited budget that is a lot of money. Some pilates classes in our area are 10.00 a session, the gym charges a monthly fee and other classes are expensive too. I walk as much as i am able to, that is my main form of exercise, gardening helps too, plus a whole day is deligated to housework and i am bushed afterwards, changing bedding and fighting with duvets, hoovering dusting cleaning bathroom etc. If i had the money i would love to go to tai chi. I know there are courses on line but it is not the same as having someone telling you if you are doing moves correctly and there is no social aspect to doing it at home. If you have the money and time you could be as fit as a fiddle with all the different things available now adays.
