VIDEO: In preparation for this Saturday’s Double Header, London Irish Rugby Club have taken on their toughest training session yet.

The club’s new three-season sponsor, sports-nutriton brand Etixx, challenged Leo Halavatau, Matt Parr, Luke Narraway, Geoff Cross and Conor Gilsenan to test out the world’s first Scrum Shop – a vending machine that invites users to pay with power as opposed to money – and the brand caught the entire event on camera for a funny video that shows behind the scenes at London Irish’s new Hazelwood training ground.
