Anthony Joshua lost his WBA, WBO and IBF titles, as well as his undefeated record, in a shock defeat by Andy Ruiz Jr in June in New York.

The Briton will be attempting to reclaim his heavyweight crown in Saturday's rematch in Saudi Arabia, and he took part in a public workout on Tuesday ahead of the hotly anticipated fight.

Looking slimmer and faster than before, Joshua is said to have lost weight in search of even more speed for the so-called "Clash on the Dunes".
