There is no doubt that there are some insanely fit and inspirational people around the globe. Challenging extreme limits of ones body may not be for everyone - but these people certainly took their love of fitness to new heights....literally.
600ft Acro Yoga
And we thought normal inversions were hard! Brian Mosbaugh and Kesley Ondine practicing AcroYoga on natural rock formations 600 feet above ground level. We'll keep working on our handstands.....
Ireland's Cliffs of Moher feature a 700-foot vertical drop at their highest point. The routes along the cliff have been named one of the greatest cycling routes in the world . This route isn't for amateur riders though - one wobble and you'll be falling straight into the Atlantic Ocean.
Photographer Alex Emanuel Koch captured this image of his girlfriend doing a handstand split on Norway's Trolltunga Rock. This is a massive tourists destination (the name means Troll's Tongue) but I think I'll stay standing at 2,300 feet.
Rock climbing is a killer total body workout! But rock climbing over open water without a harness? I hope that water isn't too shallow...
I'm certainly not one to rule out winter sports and activities - but this?! This guy brings it to a whole new level. I don't know if i'd trust a giant frozen water fall and a rope that small.....
Ah Kayaking, so peaceful on the open water. Nothing but the sound of your paddle rowing you along....oh wait. Clearly thats not how this trio chooses to do it. They paddled right up to the lip of Victoria Falls (the largest waterfall in the world) for a view of the 350-foot cascade of water. For the record - no one has ever survived that fall.
So you snowboard? Cool. So does this guy - just on glaciers. In this shot, Mark Sallors hits the lip of a natural quarter-pipe (which I don't know if I'd trust how stable that is....)
Black diamond runs a piece of cake for you? Grand Targhee Resort (where this photo was shot) boasts a vertical drop of 2,270 feet. No thanks.
Cliff diving has it all: hiking, rock climbing, swimming... but I definitely couldn't be paid enough to attempt Blake Aldridge's 95-foot dive from the rocks in the Red Bull Cliff Diving World Series in Portugal.
