Keeping water fit when away from the sea can be near impossible...however, with a little bit of imagination and a pool then you can keep your wave count up and water confidence high.

It's tons more fun than swimming. 

I'm currently in talks about creating a course with a well known gym. If you're in London and you'd be keen to know more send me an email.

The backstroke basically helps stretch the muscles you've just hammered and works on opening up the chest. 
So no excuses... go hit the pool!
