A couple of my friends made a video of themselves training towards the end of this year. Basically, the two of them are really into freerunning/Parkour and you don’t realise how hard they train and practice until you watch videos like this. Check it out – you might see them running around Portsmouth yourself one day.
Make sure you click on the link in blue above titled “End of 2011 video” to watch it!
Also, I’d advise you to stop the video around 5:00 before it descends into bloopers and the really weird sense of humour that some of my friends’ friends seem to have!
