Oxford United boss Chris Wilder says he will seek the advice of fitness experts from Super League side Wigan Warriors this summer.
Wilder's players came under fire from chairman Kelvin Thomas recently who said they weren't fit enough.
The U's owner, Ian Lenagan, is also chairman of Wigan and has urged Wilder to take advantage of the resources available to him.
"We have fantastic connections with Wigan who place a massive importance on fitness," Wilder told BBC Radio Oxford.
"It's part of the club that we need to study and improve because obviously from my point of view as manager I need players on the training ground and available for selection.
"We are always trying to make them fitter and raise the bar and make the levels better."
