I think there comes a time in many peoples lives when they just accept that they're not athletic. I've known for a while now that getting sweaty in the pursuit of fitness does not come naturally to me. I tell myself that a nearly full time job and two small kiddie winks is the reason I don't work out a lot. But, to be honest, when I was footloose and fancy free I was a lazy moo. I've always been fairly slim, (apart from at the moment, at the moment my bum is definitely on the peachy side) so I haven't felt the imperative to work out frequently. I wasn't really encouraged to exercise as a teenager and was always too self conscious to work out in front of other people. A classic recipe for exercise avoidance. Having said all that, historically I've managed to dip in and out of a regime of some kind. The gym, walking, ballet, riding, tennis, mountain biking - I've done it all in small doses, keeping my stamina ticking over.
