I get a lot of personal training ideas from videos, but Danny MacAskill’s Imaginate (below) is useless for that purpose. Just training to do some of the tricks in this video will almost certainly kill you.
Danny takes BMX biking to the next level and does what I would call bike parkour. This video is impressive both from a training point of view and an aesthetic point of view; it has very clever cinematography.
Check out the outtakes/crashes at the end!
