The Hatters had the footballs out on the grass this afternoon as head of sports science Jared Roberts followed up the personal testing in the gym with a "reintroduction football" session at The Brache.
Players including new signings Alan McCormack and Jack Stacey were reacquainted with the Mitre Delta matchballs the Town will use in Sky Bet League Two this season as the inclement weather gave them some favourable temperatures to work in – the gaffer Nathan Jones even sporting a Puma beanie hat and raincoat!
Jared was pleased with how the squad looked on their first day back less than six weeks since the final game of 2016-17.
"Everybody came back in good shape," he told lutontown.co.uk. "They've clearly stuck to their programmes over the summer as they all came up well in the personal tests in the gym this morning.
"This afternoon was all about reintroduction football, a few passing drills and light possession to get them used to having a ball at their feet again. It's been a good first day back – and it's good to be back!"
Boss Jones went on to explain how important the club's move to The Brache on a full-time basis has been in helping persuade new signings to step down a couple of divisions to join the club.
"It's a wonderful place and I'm sure we'll wax lyrical about it quite a lot, but the facilities we now have as a football club are outstanding," said the Welshman.
"The renovated buildings and the training pitches – everything about the place – are just absolutely wonderful and we thank Gary Sweet and the board for the support they've given us. It's part of why we feel we are going to move forward.
"What we've done this year, we are signing players from Championship football clubs who are used to these facilities, so when you are asking them to drop leagues, you're not asking them to drop quality.
"We believe that the facilities, the quality of our training programme, our environment and our culture, is minimum Championship anyway, so it all helps to attract these players."
