Alex Oxlade-Chamberlain, Theo Walcott and Kieran Gibbs are seen here working in the gym at London Colney.
Oxlade-Chamberlain posted the video on his official Instagram account showing him lifting weights while fellow stars Walcott and Gibbs watch on.
The Arsenal midfielder had been a fitness doubt for this Saturday's clash with Chelsea after coming off in the 1-0 win against Spurs with a tight calf.
However he appears to be in prime fitness ahead of this weekend's match with the league leaders.
Meanwhile Theo Walcott continues his rehabilitation from a cruciate ligament injury which will keep him out for the remainder of the season.
