Anthony Joshua back in the gym after knockout win against Francis Ngannou

Only four days after defeating Francis Ngannou in Saudi Arabia, Anthony Joshua is working hard in the gym.

After his incredible victory, the British celebrity is eager to get back in the ring and is making every effort to do so.

Joshua shared pictures of himself working out early in the morning in a Dubai gym with his strength and conditioning crew on Instagram.

At the end of the session, the heavyweight flexes his body and does several yoga techniques.

Anthony Joshua's next fight?

Joshua, 34, has his sights set on facing British champion Tyson Fury, but he'll probably have to wait at least a year to face the "Gypsy King".

Following their May 18 fight, Fury has an immediate rematch deal with Oleksandr Usyk.

Ngannou, a former UFC champion, was knocked down three times by Joshua in just two rounds, and referee Richard Gonzalez stopped the bout early.

In between waiting to confront Fury, the former Olympic champion revealed three names he had in mind to challenge Fury after his recent hot streak of victories in the ring.
