The entire squad, minus England goalkeeper Nick Pope and Icelandic winger Johann Berg Gudmundsson, who has been given an extended break due to his involvement in Russia, reported for duty.
A series of fitness tests awaited the players, before they hit the ground running on Tuesday in preparations for the club's first European campaign in 51 years.
The Clarets embark on a week-long training camp in Cork next week, culminating in a friendly against Cork City on Friday, July 13.
And just under two weeks later, they get their Europa League campaign up and running at Aberdeen in the first leg of the second round qualifier.
