After months and years of flip-flopping on his future in boxing, it seems Tyson Fury is finally on the comeback trail.The 29-year-old boldly announced his return on Twitter this month with his British Boxing Board of Control hearing imminent and the possibility of an Anthony Joshua mega fight on the horizon.Boxing fans haven't seen Fury step between the ropes since he danced around Wladimir Klitschko in November 2015 on his way to the WBO, IBF, WBA (Super) and IBO heavyweight titles.Since then, personal troubles have kept him from the ring while Joshua has fought his way through the ranks with an immaculate record and three of Fury's belts.AJ will be aiming to mop up the remaining heavyweight titles by putting Joseph Parker and Deontay Wilder to sleep as Fury dusts of the cobwebs in a series of warm-up bouts.And while the 'Gypsy King' insists he could knockout Joshua at 25 stone, he knows as much as any fan that he needs to find his fitness again to compete with the best.Fury warned most recently: "Anthony Joshua, I do not care about you! Like I told you before I'll punch your face in bad boy."Fighting to me is easy & slapping punks like you is even easier. Good to see Eddie has let you of your leash for the day. But he Better put you back on before u get bitten."Aside from calling out his compatriot for resembling a 'weightlifter' and taking general digs at his personality, Fury has also been keeping fans updated with glimpses into his comeback routine.Until today, however, that simply consisted of eccentric Instagram videos of him jogging in a flat cap and coat or walking his dog.The 29-year-old latest tweet has given fans a more objective insight into his intended return and exactly how much weight he has lost recently - check out the tweet below:

Certainly a solid start and fans are happy to see Fury putting in the work:

However, there's a still long way to go for Fury who recently told Dereck Chisora that he still has seven stone to lose in Monte Carlo last week.

Given that Fury claims to have lost six and a half stone in seven weeks preparing for Klitschko, though, it would be premature to write him off.

As long as he can rustle up the fitness to slog it out with AJ, everyone's a winner.
