Social influences

‘I wanted to be able to do something…with other people…I mean swimming they say is very good exercise…I love swimming but then that is an individual sort of thing and I wanted to do something with another group of people so that you had the social side of it.’ (7)

 Social awkwardness‘I started classes but they were too fast. I was the oldest one and everyone else was younger…and…the rec center which is a lot of younger people who do not share the same kinds of needs that we do. Kinda hard to race an 18-year-old, you know.’ (127)
‘I just think that maybe there's a male ego thing involved a little bit, but the guys like to be with the guys. Not that they don't love women but they'd rather be in an all-male class…You can get away with anything that you want. If you make a mistake or if you do something that's a little embarrassing, it's not embarrassing when you're with other men because the same things happen to them, whereas in a mixed class they would probably feel uncomfortable.’ (38)

‘The doctor said that I had to do exercises otherwise I would end up in a wheelchair, and I did the exercises, but I didn't really like it, it was hard. But he says if you don't do exercise you'll end up in a wheelchair, and if you hear the results of not doing it, you'd better do it!’ (120)

‘We have had good people teaching this. They had a super team and there isn't one of them who has not been nice to us you know and they're great, all of them have been super. It all helps doesn't it? If you get someone—an instructor—someone who you didn't like, he was bit nasty, you wouldn't want to come would you. When they are all so nice and welcoming they bring out the best in you, hopefully.’ (45)

Competing priorities‘…and doing what I need to do for [husband]…he has plenty of appointments…so I've come to the conclusion that there isn't much time to do anything…you always put yourself second don't you?’ (34)
‘My day is busy I don't have time to be bored, and it's hard sometimes to coordinate and that's why I had to stop um classes because it was pick-up time to drive out there and (pick-up the grandchildren), so I have trouble trying to fit classes around duties.’ (68)

Personal benefits of exercise  
 Strength, balance and flexibility‘I chose to do it [exercise]…and I chose it because when I was going to start walking, after mostly sitting for a year, I didn't have any balance. I didn't want to remain sitting.’ (33)
‘I'm more contented with my own self. It's every time I've been and I walk back across that yard I feel that I've achieved something that I've got a little bit stronger I'm more flexible. I'm not a failure. That's the way I feel about it.’ (45)

 Self-confidence‘But mainly, as I say, mainly to give you confidence. I mean as you get older you get scared especially if you fall over. I mean you think you're alright, then you don't, you know? And I mean most of the people there seemed to be pretty fit, reasonably fit, you know, but as I say, it's made a difference by um, or the main thing is giving you more confidence which is a really big thing, you know, a really big thing.’ (5)
