The England international, who completed his transfer from Borussia Dortmund on 23 July, has been away on holiday after appearing for the Three Lions in the Euro 2020 final less than a month ago.
He also played against Czech Republic and Ukraine during the competition, at the end of a demanding season in which the 21-year-old featured in 38 games for Dortmund.
Judging by his social media output over the last few weeks, Jadon has been keeping himself in shape and that work is now continuing in the gym at Carrington as you can see in our photo gallery above.
