Hat trick hero Kallum Watkins said he was pleased to be able to help his team to victory on the opening day and put his tries down to the hard work in the gym during the close season.
Speaking to Rhinos TV after the game, the centre said, "I'm not sure if I would have scored those tries in previous years. I have done a lot of work with the conditioning staff to build up my strength and I needed that tonight against a very tough Hull KR team."
