This is Dmytro Khaladzhi, a 38-year-old a former circus performer from the Ukraine. He can carry a full grown horse.
Little is known about the eastern European giant but a dubious Wikipedia page dedicated to him claims he holds 63 Guinness World Records.
It does look nearly impossible. How much does a full grown horse weigh?
The size of horses varies by breed, but also is influenced by nutrition. Light riding horses usually range in height from 14 to 16 hands (56 to 64 inches, 142 to 163 cm) and can weigh from 380 to 550 kilograms (840 to 1,210 lb). – Wikipedia
What is the maximum a human can lift?
Some sports experts believe weightlifters have reached a saturation point but the imminent question remains – what is the maximum weight a human could ever lift.
Brit strongman Andy Bolton set the heaviest dead lift record when he lifted 457.5 kilograms from the floor to his thigh. The record for an overhead lift stands at 263.5 kilograms.
According to Dan Wathen, an athletics trainer at Youngstown State University, Ohio, Bolton and weightlifters like him are nearly five or six times stronger than the average man, who will struggle to lift 45 kilograms over his head, reports the New Scientist.
Todd Schroeder at the University of Southern California in Los Angeles, says, “If you look over time at the records for maximal lifts, they have crept up but are starting to plateau.” – TheHindu
If the world’s best lifter can man can lift 1,008 lbs (457.5 kg) to his waist, it does seem within the realm of possibility that a man like Dmytro Khaladzhi could carry a 900 lb horse a few steps. He would need outside help getting the horse up to his shoulders, however.
