The 31-year-old is currently recovering from a hamstring injury he suffered in the Premier League clash between Tottenham Hotspur and West Ham on February 22.
Cole suffered the injury in the second half of the match at White Hart Lane and was substituted in the 68th minute.
The striker has since missed West Ham’s league games against Crystal Palace and his former club Chelsea at the Boleyn Ground.
Cole has now taken to Twitter to reveal that he is training on his own at the moment, and the problem he is facing in doing so.

Cole has been largely a peripheral figure in West Ham’s 2014-15 campaign so far, having been able to make just 14 Premier League appearances.
The veteran has scored only twice in those games, while creating five chances and having a pass accuracy of 51%. Cole, though, has a shot accuracy of 80%.
West Ham are currently 10th in the Premier League table with 39 points from 28 matches, as many as 12 points behind fifth-placed Liverpool.
