Ben Affleck's DCEU trainer offers up that he wants to get Robert Pattinson jacked for Matt Reeves The Batman movie.

It's unknown if Rehan Jalali is actually training Robert Pattinson or if he simply is offering his services but in a tweet, Jalali remarked: "we’ll get Robert Pattinson jacked!!"

Robert Pattinson having trouble bulking up for The Batman

It's actually been rumored that Robert Pattinson is having trouble bulking up for The Batman, which is causing the movie to be delayed.

If Rehan Jalali is indeed training Robert Pattinson now, his tweet seems to corroborate the rumor.

Again, Rehan Jalali could simply be stating he could help with Pattinson putting on weight for The Batman, so there may not be any insider knowledge.

Rehan Jalali is the author behind "The Six-Pack Diet Plan" and is a "Body Transformation Specialist." As noted, Jalali helped Ben Affleck get into the best shape of his life to play Batman for director Zack Snyder as Affleck packed on 24 pounds of muscle for the role. "The Six-Pack Diet Plan" saw Affleck eating six to seven small meals a day featuring 45 percent carbs, 35 percent protein, and 20 percent essential fats.

Regarding Robert Pattinson, it's claimed he is having trouble packing on muscle for his role which is causing production to be delayed at least a couple of weeks. As I speculated, the reason for the delay is because of the need to create the new Batsuit, which obviously would need to be fitted to Pattinson's body. If they want Robert Pattinson to have a bit more muscle, obviously they couldn't create the new Batsuit until Pattinson is at the weight they want him.

Pattinson is a rather slender dude, so he might just need the right diet to pack on the pounds. Rehan Jalali seems to be someone with the knowledge to help him get there.
