Sam Allardyce took his Sunderland squad to the seaside for a training session with a difference this week.
So we thought we'd delve into the archives here at the Echo to bring you a gallery of training pictures from years gone by.
Sunderland players from as far back as the 1940s can be seen exercising on the promenade, doing gym work in Washington and training at the club's former ground, Roker Park, in our gallery of images.
Sunderland greats Len Shackleton and Billy Elliott are included in the images, how many more Black Cats legends can you name?
