Designed by rowing champion Josh Crosby and fitness educator Jay Blahnik and already a hit in the US, the 50 minute class aims to beboth exhilarating and motivational, by encouraging participants to work as part of a 'crew'.

The interval-based workout involves a series of drills, starting at a slow and steady pace, and then building in intensity to test speed, stamina and determination.

Participants use specially designed WaterRower Indo-Row machines, which are equipped with an Indo-Row/Pace Coach monitor, providing instant feedback on pace, distance and calories, so they can monitor progress.
