First up, a lengthy gym session to prepare for ball work and running in the heat at Hotspur Way.
The players were split into groups of three for the runs.
The squad are back out this afternoon for the second session where they will concentrate on technical and tactical work.
Look out for pre-season updates on our social channels - Facebook, Instagram and Twitter - including the all-new Eric Dier's Diary #DiersDiary.
COMING SOON - Assistant Head Coach Jesus Perez talks us through pre-season - part one tomorrow!
