I was reading some articles on functional training and I came across this article: "Fitness to survive" (google it).
This men basically trains like a caveman everyday, it's a mix between parkour and strongman stuffs, he's climbing, a lot of deadlifting (of course) and lunging/high-step-up pattern (unilateral strength haters won't like it ^^), carrying odd rocks objects/logs, he's jumping, running on different surfaces, swimming..
Funny fact, he's friend with David belle, original creator of "Parkour", they started training together before parkour was created, and they went different way, "parkour" didn't include lifting/carrying heavy object, wich is the main difference.
This is the real definition of being fit. It's really inspiring.
Take a look at it if you wanna try something different.
There are some good videos interview you can find with google.
This is something different, enjoy or hate ^^.
