The first team players haven't been the only ones back at work this week.
The Tigers' youth team squad has also reported back for duty and the youngsters have been put through their paces down at the Ideal Standard Centre of Excellence.
Running, ball exercises and ice baths have been the order of the week so far, all under the watchful eyes of Billy Russell and Neil Mann.
Despite the heat and humidity rising by the day, there have been some full-on sessions and Head of Youth Russell has been pleased with the application of his players.
"We're all glad to be back out there," said Russell.
"It's been a short break really with all of the preparations for the EPPP (Elite Player Performance Plan), but we're back out there coaching now and that is the thing that we look forward to and it's what it's all about.
"The lads have been good this week and we've got another bunch of decent lads this year. We're going to make sure that, as a staff, we set out to challenge them as much as we can to get the best out of them.
"But in terms of pre-season, we're linking in with the first team and doing similar forms of testing. We've also got a few friendlies lined up to help get us prepared for the season."
Amongst those at training this week have been a new batch of first-year scholars.
Max Clark will be the most familiar to City fans with the local youngster having already represented England at U16 level and played for the reserves last season. He is joined by Leon Dawson, Niall Doran, Eoghan McCawl, Sam O'Connor, Rory Watson and Ryan Fallowfield on first-year terms and Russell is pleased with how they're settling in to day-to-day life with the club.
"They're settling in well," added Russell.
"We've got some local lads there who have been with the club for a number of years and we've also got a couple of boys who have come over to us from Ireland."
