The Sydney Swans second-to-fourth-year players returned to the training track on Monday morning to begin preparations for season 2018.

Gloomy skies and ominous clouds greeted the players as they took part in skills sessions broken up by running blocks around Darlinghurst's Weigall Fields.

The rain came then went. Regardless, the moisture and ensuing humid conditions failed to dampen the boys' enthusiasm and work ethic during the two-hour session which was followed by gym work back at the SCG.

Isaac Heeney and Callum Mills led the charge on the opening day which featured players in their second, third and fourth years of football.

Their more experienced teammates return in a fortnight's time.

Alex Johnson and Sam Fisher were also among the group to return on Monday, the pair fighting hard to earn back a spot on the list following their delisting in the off-season.

There were also some fresh faces among the coaching ranks with Steve Johnson, Dean Cox, Jeremy Laidler and Tadgh Kennelly starting their new roles.

Kennelly fronted the media following the session for the first time since returning to the football club where he played 197 games and won a premiership.

Showing a hint of few nerves, the 36-year-old development coach couldn't have been happier at being back in clubland and with the boys' performance on the track.

"(I was) probably a bit apprehensive about coming back in again - it's like my first day of school," Kennelly said.

"Most of the players have moved on, there's still a couple left, but the coaching structure has changed dramatically.

"A bit nervous, I was, but I've been back for a couple of weeks now and we're no back training.

"It's always interesting watching. You can pick up a few things from the young men when they arrive at training. You don't have control over them for the eight weeks while they're away but they all showed up pretty well today."

The hard work continues on Wednesday.
