I have to agree about the benefits of starting to work out again. My wife and I started going to a local community-center gym once a week. We go on nights where it is not so crowded. On Tuesday and Thursday there are maybe 10 other people there and we pay about $2-3 per visit. If we want to buy a card, we can reduce that to about $1.
My wife mostly does cardio but will probably start doing some light weight work soon. I do about 50/50. I am 59 and my wife is older. We both feel great when we come back and after a shower, it often leads to other things. We are both still in decent shape, but want to get the metabolism going. I spend too much time in front of a computer (for work) and want to get flexible again...
