New 2016: Ma Long - Rio Olympic Training!

How is that ? You see a video of Ma Long , don't see a video of ZJK , and none of us have any clue of how hard either of them are working . for all you know Ma Long might have only practiced for 5 minutes that day to make this video ...

At the max we can think ... "I wonder is ZJK also working this hard , might not be he seems to always have fitness issues ?"

watching this video I was thinking "ZJK definitely is not working this hard" :D
