Dieselnoi Chor Thanasukarn was one of the most ferocious knee fighters of all time. This short training clip demonstrates the immense power he was able to generate in his knee strikes, and the huge height advantage he had over opponents at the same weight.
Dieselnoi became Lumpini champion and went undefeated for 4 years, winning the prestigious “fighter of the year” award in 1982 before retiring due to the fact that nobody wanted to fight him anymore.
