The U's squad were back for pre-season training on Wednesday morning.
They were put their paces at Florence Park and the indoor dome, with Sports Scientist Stefano Russo overseeing things.
Stef and his staff had plenty of work for the players to get through, as well as taking height, weight and body fat measurements after the close-season break.
Standing jumps, using both feet and one at a time, and short standing start sprints were completed before the players enjured the Yo-Yo test.
Stef explained: "Everything we do today gives us an idea about how well the lads worked on their summer schedules while they were away, what they're fitness levels are like and how much work they have to do to get to the levels required for the start of the season."
"We have a schedule to work to but that obviously depends on these fitness levels being where we want them to be - the better the fitness now, the quicker we can start doing ballwork as well as fitness work.
"The Yo-Yo Endurance Test is designed to estimate an individual's maximum oxygen uptake, but it basically means running between markers at increasing speeds until they can't keep up with the beeps."
"If done correctly, it's very tough because you're basically running faster and faster until your body can't run any more."
'The lads have worked hard today, so we may well have the balls out as early as tomorrow."
