Ireland's John Lacey will referee his first ever RBS 6 Nations match in February, while Alain Rolland is also included in the Elite Panel in what is his last season.
Moving out of their normal environment at Newforge Country Club, the players went through rigorous tests including shuttle runs along the beach, relay races up the sand dunes carrying 20-kilogram weights and touch rugby sessions in the sand.
The reason behind the squad's change of training venue is to have a testing environment, which includes experiences the players bodies are not used to training in.
Throughout the pre-season session, each player's individual performance is closely monitored to increase personal fitness levels and limit the risk of injuries.
Ulster's Operations Director David Humphreys, new forwards coach Jeremy Davidson and the Ulster Academy's Elite Player Development Officer Jonny Bell were on hand to oversee the progress of the players.
With their normal ice baths shelved for the day, the players took a well-deserved dip in the North Atlantic Ocean afterwards.
