First team coach Chris and reserve coach Clive Allen oversaw proceedings as the squad was split into three groups with fitness and rehabilitation coach Alex Court monitoring results of various running tests.
Chris said: "The most important thing for us is that the lads are pleased to be back and in good humour as always, so that's the good part of it.
"The other part and of course the serious part is enabling us to get some testing done at this very early stage of pre-season.
"The tests are short and sharp and give us measurements to work off for the rest of pre-season.
"They are not long and drawn out and we've come away from 15 or 20 years ago where the first few days would be all about endurance running.
"We play Stevenage next weekend and that's an aspect that has changed over the years - the football work and games come a lot earlier.
“The thing you think about most at this stage is fitness and building up over a period of time to take us into the friendlies.
“This time we go to South Korea, a very big trip for the players and the club and at the end of pre-season we’re always very confident that we’ll have it right for the first league game of the season."
Chris Hughton reported that the lads were in good spirits as the hard work began on the first day of pre-season at Spurs Lodge on Saturday.
