The five Leicester Tigers in the England training squad have been working hard in camp ahead of the summer series of games.
George Ford, Ellis Genge, Jonny May and Ben Youngs are in the squad for the three-Test tour to South Africa in June.
George McGuigan, meanwhile, is in camp as England prepare for a non-Test fixture with the Barbarians on Sunday, May 27.
Youngs posted the photo below of himself hard at work on his own Instagram page.
