Michael Phelps has been working out with his former coach but is still not ready to announce a much-speculated comeback to swimming in time for the Rio Olympics.
Bob Bowman told The Associated Press on Sunday that Phelps has been swimming occasionally with the North Baltimore Aquatic Club - largely as a means of getting in better shape.
Phelps and Bowman remain close friends and business partners.
The winningest Olympian with 18 golds and 22 medals overall announced his retirement from swimming after the 2012 London Games.
Initially adamant he would never compete again, Phelps softened his stance this past summer after reports began swirling of an imminent comeback. He told the AP during the world championships in Barcelona that he doesn't "know what's going to happen in the future."
