Melanie Wilson from the GB Rowing Team shows you how to use a rowing machine or ergo to train for and take part in The Nation on Trial. The GB Rowing Team invites you to get fit in February 2012 and put yourself to the test with a 2K trial - just like our rowers in this important year for British Sport! The challenge is simple, fun and open to everyone of any ability aged 16 and over. Get on a rowing machine, train and register your best 2K time in February. That's the race distance for Britain's rowers at the 2012 Olympic Games and the distance used for the GB Rowing Team Senior Trials in early March.
