Sometimes you see footage of a human feat that simply astounds you. You watch it again, and again. Sometimes the phrase OMFG is simply not enough!
Step forward Norway's Andreas Thordkilsen who nails an incredible jump here. Andreas is an Olympian in the Javelin and at 6'2" tall (190cm) and around 200lbs (88-93kg) is no lightweight. He undertakes gymnastics as part of his training but is not (nor has he ever been), a competitive gymnast, which makes this iron cross pretty bloody impressive.
More details at Gymnastic Bodies where, amongst the comments is buried this gem showing some not-too-shabby tumbling. Sure there are better tumblers around, but how many tumblers do you know who have won four Olympic golds and five World Championships in alpine skiing like Kjetil Andre Aamodt - the athlete tumbling here?
Let's not get to bogged down in what is and what is not 'gymnastics'. The point being that if it involves strength, speed, agility and kinaesthetic awareness - primal qualities, training can manifest itself in many forms.
