Our #ManCrushMonday officially goes out to Idris Elba.

The actor took to Instagram today to share a photo of himself after hitting the sauna, and let's just say the steam wasn't the only hot thing in the room. In the snap, the 43-year-old star poses in nothing but a pair of tiny black shorts as his chiseled muscles glisten with sweat. The Thor: Ragnarok actor flexes his bicep for the camera and shows off his whole rock-hard physique in the process. Talk about a body of steel.

"Cutting weight, two days before first fight, mind in the right place," Elba captioned the image. "Fear NO guy."

The avid boxer has been spending a lot of time training in the gym for various action roles as of late, but it looks as if the actor may be stepping into the ring for his first real fight in the coming days. Check out more of his training 'grams below.
