Watch: All Blacks hit the gym before Barbarians clash

The All Blacks have begun their preparations for Sunday's clash with the Barbarians by hitting the gym at their London hotel.

Steve Hansen's men are in England to kick-off their end-of-season tour of Europe, which begins at the weekend at Twickenham.

And after arriving in Teddington at the familiar Lensbury resort - where they stayed for the 2015 World Cup - they made a trip to the hotel's weights room.

Beauden Barrett and Aaron Smith were among the New Zealand rugby stars to work on their strength ahead of the highly-anticipated clash.

Peter Gallagher, the All Blacks physio, was a busy man as he prepared the players for the Twickenham showdown.

Barrett and Co will also travel to France, where they face a double-header with the hosts, before visiting Scotland and Wales.
