British heavyweight Anthony Joshua has returned to the gym following the recent car crash which killed two of his close friends and team members.

The former world heavyweight champion, 36, sustained minor injuries in the incident in Nigeria on 29 December.

Sina Ghami and Latif ‘Latz’ Ayodele died when their vehicle, in which Joshua was also a passenger, collided with a stationary truck on a major road near Lagos.

Nineteen days after the crash, Joshua has posted a video on Snapchat showing him hitting pads and working out, with the message “mental strength therapy” at the bottom of one clip.

He beat Jake Paul in Miami on 19 December, 10 days before the crash occurred while he was on holiday in Nigeria.

Last week he posted a tribute to his strength and conditioning coach Ghami and trainer Ayodele on Instagram., external

“I didn’t even realise how special they are,” he wrote. “I’ll just be walking with them and cracking jokes with them, not even knowing God kept me in the presence of great men.

“100% it’s tough for me, but I know it’s even tougher for their parents.”
