Former World Heavyweight Boxing champion Anthony Joshua has returned to the gym following the recent car crash which killed two of his close friends and team members.

The 36 year old British fighter sustained minor injuries in the incident in Nigeria on December 29.

The 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 December 19, 10 days before the crash occurred while he was on holiday in Nigeria.
