We won't waffle when it comes to looking at these Belgian runners.

 Three-quarters of Belgium's men's 4x400 relay team at the Rio Olympics is made up of brothers from one family.  

Leg 1 of Belgium's team, which qualified for tonight's final, was run by Julien Watrin. After that, the Borlée Brothers took over, with Jonathan followed by Dylan and then Kevin running the anchor leg. Kevin and Jonathan, both 28, are twins. Dylan, 23, is the baby.

The athletic bloodlines extend to their sister, Olivia, who qualified from the Olympics in the women's 200 meters.

The brothers are not shy of posting shirtless shots on their Instagram pages (Kevin,Dylan, Jonathan).
