Is anyone teetotal?

As for exercise swimming is probably the most low impact exercise you can do. Alot of the time I alternate front crawl with just my arms then back stroke with just my legs to give myself a bit of a rest. You just need to go up to your local pool and plonk yourself in the slow lane and paddle along at f*ck all speed as just getting used to using it is important. Quitting before your tired or hurt is also important.
