Wigan Warriors coach Shaun Wane believes a mid-season training camp with rugby union side Bath will prove to be beneficial to both clubs.
With Wigan not involved in Saturday's Challenge Cup final at Wembley, Wane's side headed to the south west to train with the Premiership outfit.
"There are areas that we can copy and improve," h said.
"The recovery facilities and how they look after players from a nutritional point of view are the two main things."
Wane, who guided Wigan to a Super League and Challenge Cup double in 2013, continued: "On the field, we did a lot of our attack and they tried to copy what we were doing.
"They learned a lot from us and we learned a lot off the field about what we can do within our budget. It's been worthwhile doing and I'm glad we did it."
Bath head coach Mike Ford is an expert on both codes and started an 18-year rugby league playing career at Wigan in the 1980s.
The former England rugby union defence chief was delighted with what his troops got out the camp and believes it will be a big benefit once the competitive campaign gets under way next month.
Ford said: "It's been a fantastic experience for us; better than I'd hoped.
"You're always looking to freshen things up. I could see an extra level of intensity from us and when we went away to train on our own we kept that same intensity up.
"As soon you put a group of players on a field they want to compete. There's nothing better for a coach to see than that. You can't go to another rugby union club and say "what are you doing?" So it's been good to exchange ideas this way.
"You get ideas watching games but when you work with them live you get to know the real nitty-gritty side of it.
"Even if it's just half a step here or half a step there, it could be crucial with the level of detail these guys put on it."
