Mark Wahlberg seems to be telegraphing a certain message with his latest thirst trap post -- which comes on the heels of David Beckham's lawsuit against his fitness company.

The actor threw up a video Wednesday on his IG page, and while it wasn't the first thing he's posted since David filed suit against Mark's F45 training brand ... it is the first one where he's shirtless and barking aggressively, interesting considering what's going on BTS.

The video's pretty simple ... it's Mark standing outside in the wee hours of the morning -- 4 AM, apparently -- which seems to be the start of whatever workout routine he's getting into.

Sylvester Stallone came within a hair's breadth of tanking "Rocky II" because of a gruesome injury, and you won't believe how he powered through to shoot the flick!

Sly and Arnold Schwarzenegger sat down with Harvey, and for the first time ever together they talked about their unbelievable rivalry and how it blossomed into a close friendship.

Arnold's trainer and compadre, bodybuilding legend Franco Columbu, trained Sly for "Rocky II," and when Franco challenged Sly to a bench press competition, the actor was game ... until he ripped his pec off the bone.

Sylvester Stallone estuvo a punto de fracasar en "Rocky II" por culpa de una horrible lesión, ¡pero no te vas a creer cómo se las arregló para rodar la película!

Sly y Arnold Schwarzenegger se sentaron con Harvey, y por primera vez juntos hablaron de su increíble rivalidad y cómo esta se convirtió en una estrecha amistad.

El entrenador y compadre de Arnold, la leyenda del culturismo Franco Columbu, entrenó a Sly para "Rocky II", y cuando Franco retó a Sly a una competición, el actor estaba dispuesto... hasta que le arrancó el pectoral.

Two fitness titans are on a path to square off in court, because David Beckham has sued Mark Wahlberg's company over a fitness deal that made the former soccer star way lighter in the wallet.

Beckham's company, DB Ventures Ltd, alleges in the lawsuit F45 "duped" him into signing on with F45 Training, a company in which Wahlberg has a 36% interest. M.W. also serves as the company's chief brand officer.

Beckham, who got close to Mark when he moved to Cali to play for the L.A. Galaxy, became F45's Global Ambassador. The selling point -- David has millions of social media followers, so it would presumably greatly expand the reach of the company.

Dos titanes del fitness van camino de enfrentarse en los tribunales, porque David Beckham ha demandado a la empresa de Mark Wahlberg por un acuerdo de fitness que aligeró la cartera de la ex estrella del fútbol.

La empresa de Beckham, DB Ventures Ltd, alega en la demanda que F45 lo "engañó" para que firmara con F45 Training, empresa en la que Wahlberg tiene una participación del 36%. M.W. también es el director de marca de la empresa.

Beckham, que se acercó a Mark cuando se mudó a Cali para jugar en el L.A. Galaxy, se convirtió en Embajador Global de F45. El argumento de venta: David tiene millones de seguidores en las redes sociales, por lo que presumiblemente ampliaría enormemente el alcance de la empresa.
