How does Serena Williams have the body she can show off in h magazine? Well, she’s punching her friend in the stomach – that’s the latest of Serena’s weird training techniques. Just kidding, Serena’s shared with us her fun times.
The tennis star also asks the viewers what they think of the jab. I can say it’s not a bad entertainment method if you’re really bored. Thanks for the hint, Serena!
