Physical endurance is my weak spot, I build muscle fast: Musk

Elon Musk, who was seen lifting a 45 lb weight recently, said he's aiming to get to "50-pound free weights this week". "I build muscle fast. Physical endurance is my weak spot, so I'm aiming to make this quick," he stated. This comes after Musk announced that a cage fight between him and Mark Zuckerberg will be live-streamed on X.
