Leicester are at the top of the Premier League table at the moment with 53 points from 25 matches.
The Foxes are five points clear of second-placed Tottenham Hotspur and are one of the top favourites to win the league title this season.
Warburton is impressed with the performances of Claudio Ranieri’s side, and has explained why they are achieving success this campaign.
“Leicester aren’t involved in Europe for example so I was looking the other day at the number of games they have between now and the end of the season and I think it’s a game every 8.4 days or 8.5 days,” the Englishman told Rangers’ official website.
“Teams like Liverpool have got 25 or 26 games so the loading on their players and the demands on their squad is significantly higher. So I think that has been a big part of it.
“Leicester have really used their time well, their rest and recover has been well structured, the support team around the first team is obviously first class in terms of medical and conditioning.
“They’ve got the nutrition right, they’ve got the bonding right with the players, so I think it’s more basic. I don’t think it’s about formation, I think it’s more about getting the loading right with the players and getting that correct.”
Rangers are also having a good season and are favourites to gain automatic promotion to the Scottish Premiership.
The Gers are at the top of the Scottish Championship table at the moment with 59 points from 23 matches.
The Glasgow giants are eight points clear of second-placed Hibernian, who have a game in hand.
Rangers will return to action on Saturday afternoon when they take on Alloa Athletic away from home at the The Indodrill Stadium in the Scottish Championship.
