Since the '80s, the King of Pop Michael Jackson awed his fans with his talent for dancing. But he especially boggled the minds of many in his music video for Smooth Criminal, where Michael iconically tilted his body in a 45-degree angle when it's only humanly possible to do just 25-30 degrees, neurosurgeon Dr. Manjul Tripathi explains in an interview with CNN—and that's granted you have a strong core.
So how did Michael pull this off? The renowned singer simply played with illusion and wielded the power of fashion at the same time. A paper written by three neurosurgeons, led by long-time Jackson fan Dr. Nishant Yagnick, divulged that MJ was able to execute the dance move through a special shoe that he designed.
In fact, this invention has "a patent registered under his name," the published journal titled Journal of Neurosurgery: Spine says. "Along with fellow inventors, MJ developed a special shoe that had a slot in the heel. The triangular slot could engage a hitch member (a metallic peg, which emerged from the stage floor at just the right time), allowing the dancer to obtain the right amount of extra support to be able to lean forward beyond physiological limits."
But the paper's authors also notes that "even with specially designed footwear and the support of the hitch member, the move is incredibly hard to pull off, requiring athletic core strength from strengthened spinal muscles and lower-limb antigravity muscles."
