The Englishman, who is only 31, has been struggling for fitness.
His contract with Trabzonspor in Turkey was terminated in March when he got a four month betting ban. Now Sturridge is fit and is hoping to find a new club.
"Still active and focused baby," he wrote on Instagram on Sunday.
"The comeback is near."
The player has been training with Kidsgrove Athletic, who are in the eighth-tier of English football.
Kidsgrove chairman Mick Fitzjohn told the Stoke Sentinel: "He's coming down to keep himself fit and he's working hard while he finds a new club.
"He comes down most days and he can let himself in. He lives locally and we don't mind that. It's a nice set up.
"I've been down there painting but we haven't chucked him a brush just yet to help out."
