The start of pre-season is a time for players to push themselves to their physical limits as they aim to get up to speed ahead of the new football season.
However it's not all bleep tests and hours spent running up hills.
A key part of many clubs' process is welcoming the newcomers into the squad by with something of a baptism of fire.
Of course, we're talking about the initiation ceremonies.
While several Arsenal youngsters were initiated for making the jump to first team level, it was very much the same for Freddie Ljungberg.
The Gunners favourite previously held the role of under-23s coach, but with Unai Emery looking to improve on last season's performance, he has promoted the former winger to first team duties.
Ljungberg has taken on the role of assistant first team coach where his knowledge of the game - along with his rapport leading Arsenal's young prospects - will be used to the benefit of Emery's side.
While he's not technically a new addition to the club, he was still put through his paces in his initiation, with the 42-year-old made to stand on a chair and sing to the congregated Gunners camp.
While it's hard to tell what song he's singing, one Twitter user said that it was by Swedish singer-songwriter Tomas Ledin called ”En del av mitt hjärta” (A piece of my heart).
Whatever it was, Arsenal's fans were loving every minute of it.
