The France international returned from his summer holidays in Senegal on Thursday ahead of pre-season training with his Liverpool team-mates at Melwood.
The 25-year-old centre-half wasted no time in his bid to return to full fitness as Sakho headed straight for the gym on Friday morning.
And the former Paris Saint-Germain defender sparred with his trainer in the boxing ring in the above clip that he posted on his Instagram page.
Sakho wrote: “Back to training !! #Boxe #Plaisir #comeback #Liverpool #soon”
The Liverpool defender uploaded another Instagram post with more action shots from his Friday morning workout.
Sakho may have drawn inspiration from his Reds colleague Daniel Sturridge after the striker uploaded a video of a sparring session with a boxing bag yesterday.
Liverpool face Stoke City, Arsenal, Manchester United, Everton, Tottenham Hotspur, Chelsea and Manchester City in their first seven away games of the 2015/16 campaign.
