My Arms Are Trembling Watching Serena Williams's Boxing Session With Mike Tyson

There's strong, and then there's Serena Williams boxing with Mike Tyson strong. Over the weekend, the two legends got together for a private boxing lesson, and if you thought Serena's forehand was intimidating, just wait until you see her throw a punch. Serena is currently training with her coach Patrick Mouratoglou at the annual Mouratoglou Preseason in Florida, when a visiting Mike came to switch things up. "The aim is to bring together current and upcoming players, as well as celebrities from the world of entertainment for a unique team-building opportunity ahead of the upcoming season," WTA said of the event.

Mike showed Serena where to hold her hands and the proper positioning of her feet, and since we're all aware of her insane strength, it makes perfect sense that Mike had to hold down the free-standing punching bag while she hit it. "Wouldn't want to get in the ring with this GOAT," Mike wrote on Twitter. There are few people who have the title of the GOAT in their respective sports — the greatest of all time, that is — and when two GOATs like Mike and Serena get together, mind-blowing workouts ensue. Check out the videos of Serena boxing with Mike ahead, and prepare to be impressed.
