It's been a remarkable year for Stuart Lancaster and his Leinster rugby team, winning both the Pro14 and the Heineken Cup, making them the most successful Irish rugby team of all time.
Lancaster managed England RFU between 2011 and 2015, taking over a team in despair after the departure of Martin Johnson.
But, with all his successes as a national manager and at Leinster comes a lot of hard work and tough-loving.
Speaking to For Fit Sake Podcast this week, as per punditarena.com, was his team's strength and conditioning coach Cillian Reardon, who gave us an insight into the Lanacaster's unique 'stuesday training sessions'.
“Basically a system of three teams out (in training) and they play phase after phase after phase and it’s pretty much non-contact, but the amount of phases that we play and change the position of where the ball is on the pitch and what teams are facing each other.
“So depending on how tough (Lancaster) wants that session to be, he’ll either do it for 15 minutes, 20 minutes or 40 minutes, but players know that they’re essentially going to have to play fifteen-on-fifteen rugby and deliver quality in that session in a sort of, fairly, chaotic scenario.
“I think those days are really useful and that’s more or less what I’m describing when I’m saying Leo and Stuart are running a program there that conditions players for the game without having to lean on massive intervention from (strength and conditioning) staff.”
The recent success of the Ireland-based Leinster is largely due to the impact of Lanacaster, a man tipped for the Ireland job come the stepping down of Joe Schmidt.
But 'Stuesday' can't come quick enough for the boys in blue, who were granted a difficult group for the upcoming Heineken Cup, with four-time winners Toulouse, Wasps and Bath.
