Forget the “Riff” and on with the ripped! Rapper Riff Raff took to his Twitter on Wednesday, Jan. 28, to proudly unveil his weight gain of a whopping 55 pounds.

The added pounds, however, have been an intentional process for the jacked artist. Riff Raff (who famously inspired James Franco‘s character in Spring Breakers) recently announced that he has been training with Hulk Hogan to pursue a professional wrestling career. Last fall, Riff Raff, 33, told his Instagram fans that he was starting a “VERSACE STRENGTH TRAINING” session to shape up, and part of his routine included abstaining from all alcohol and drugs for 100 days.

Riff Raff’s world-famous trainer also shared the news last month, which many took as a joke after he tweeted: “Can’t wait to start training with my new partner @JODYHiGHROLLER !!! Hulkamania is going NEON brother! HH.”

On Wednesday, the “Illest” rapper proved that it wasn’t a joke. “170 TO 225 POUNDS,” Riff Raff tweeted alongside before-and-after pictures. The rapper’s insane new physique and bulging biceps were on full display in the gym snap, in addition to his firm (and tan!) chest.

Riff Raff shared another body-baring photo of himself last week, this time without a shirt. In the pic, the rapper flexes HIS GUNS IN a post-shower selfie. Accompanying his photo was hypothetical commentary from ESPN. “AT 6’2 224 POUNDS JODY HiGHROLLER iS LiTERALLY ONE OF THE BiGGEST ARTiSTS iN THE LEAGUE,” he hilariously wrote in the imagined quote.

Riff Raff’s weight gain process was captured in a mini-documentary posted to Vice this past week. “You gotta get bigger, faster, stronger,” he noted of building muscle mass. The rapper added that he was “gaining weight and feeling great,” and nowhere near done. “Every day I’m gaining weight. By this time next year, I want to be 250,” he noted in the mini-doc.

As for how he’s managed to pull off his astounding weight gain? It’s certainly not from eating healthy. “I don’t want to hear that s—,” he notes. “I don’t want any rules… tell that to the pythons.”
