Before the Warriors-Nets NBA game on Thursday, December 22, Stephen Curry tried out a unique warm-up. 

The 2015 NBA Most Valuable player Curry performed an elaborate pre-serve routine and jump served a basketball with some sort of a slide approach from the sidelines. His warm-up also included a handful of football movements.

You wouldn't know it from his arm swing, but Curry's sister Sydel plays volleyball at Elon where she is a junior setter. The sibling's mother Sonya also played at Virginia Tech. 

Like many professional athletes before him, Curry has learned that volleyball's a lot harder than it looks.
