Eddie Jones has prepared an interesting innovation to help take his England side another step closer to a third-straight Six Nations title.
When England take on Scotland at Murrayfield on Saturday you might notice that their substitutes will be wearing some special clothing.
Since taking charge, Jones has placed huge emphasis on the role of replacements during matches and the Aussie has really gone the extra mile to ensure everyone he chooses to bring on can have no excuses for not making an impact.
According to the Daily Mail, the idea is for each member of the squad not in the starting XV to wear heated trousers on the bench.
At first, it might sound a little bizarre and something that is unlikely to have that much of an impact but it has been done before in other sports - with positive outcomes.
For example, at the 2012 London Olympics, British cycling athletes wore them to help their muscles loosen up and their results that summer spoke for themselves.
The trousers can generate up to 40 degrees Celsius of heat, and they are just the latest in a line of innovations that Jones has bought to the England side.
The former Japan coach has also brought in drones to film training and provide footage of running lines of the players.
Perhaps the most unorthodox training method brought in is to have the team practice line-outs wearing boxing gloves, and with washing up liquid on the ball.
Of course, Jones' aim is to give the England side every possible advantage they can get during the game in order to beat their opponents.
The hot trousers will get their first bit of action come Saturday at Murrayfield, where the temperature is expected to be a rather cold three degrees at the 4:45pm kick-off time.
Jones has also had his side scrummaging other established national teams in training as well as meeting the likes of Danny Kerry, Pep Guardiola, Arsene Wenger, Antonio Conte and Gareth Southgate to pick their brains.
It will be very interesting to see what effect, if any, these innovations have on the England side in the coming games.
