Training at altitude and cryotherapy sessions are versions of how staff bring Rugby World Cup squads to peak fitness.
The All Blacks went through a series of SAS sessions before the 1999 tournament and four years later the Springboks were put through the shame of Kamp Staaldraad in preparation for the tournament.
It was a bizarre arrangement on many fronts.
The Springbok squad had been named but coach Rudi Straeuli suggested to them that Camp Barbed Wire would confirm places for the trip to Australia.
He pitched it as a bonding camp but many, including captain Corne Krige, felt degraded and humiliated by their treatment.
