Porto Seguro - The German team got some motivation help from explorer and adventurer Mike Horn during a sailing outing near their camp on Brazil's Atlantic coast.
Horn talked about his exploits, such as the solo circumnavigation of the Arctic Circle and a North Pole expedition.
Germany captain Philipp Lahm was impressed, saying it was "incredible what the human body can achieve."
Lahm says the presentation by the South African-born Swiss explorer showed that "we must be well prepared, and have to respect the opponent."
