Serena Williams and husband Alexis Ohanian competed in the fitness competition over the weekend and according to Williams, there were parts that were a bit of a struggle.  

  “This first video was a 5 and a half foot jump half way through I knew there was no chance to get my legs over so I remembered my gymnastics classes from my youth! The rings lol look I tried! Hahahah,” she wrote.  

Is there anything she can’t do? Nope, she can do everything!
