Khabib Nurmagomedov is one of the most feared fighters in the UFC.

The 31-year-old holds a perfect record through 28 professional fights with eight of those victories coming via KO/TKO and 10 coming via submission. Khabib is reportedly set to defend his UFC lightweight title against Tony Ferguson early next year in New York and he’s already training in an unusual way.
 

This past weekend, Khabib revealed a new part of his training regimen which includes him swimming against stream in an icy cold river in Russia, which is pretty wild even for a man who has wrestled bears.
