You'll never say you don't have time to work out again

How often do you use the excuse that you don't have time to work out?

Well, Liam Finn - the high-flying, over-achieving Kiwi - has just schooled us all on the art of multi-tasking, posting the below video on his Instagram account.

Simply captioned "My workout" the video sees Finn running on a treadmill in just his underwear, playing a range of instruments at the same time. Somehow he manages to keep his feet (though the video is suspiciously short, even by Instagram's standards).

Please do not try this at your local gym. They might not let you back in.
