When people ask What Is The Hardest Sport, MMA or boxing often tops the list. Sport is a very demanding, physically, mentally, and emotionally, of these athletes. Every day, fighters are training for hours, exhausting their strength, speed, and endurance, and learning complex techniques. And they're exposed to an injury risk every single day, while playing against men under extreme pressure who are trying to take their collective lives as well. Unlike team sports, the fight is 1 v 1, and the fighters are alone in the ring or cage, relying only on their skill and willpower. That’s why MMA and boxing are widely considered among the Hardest Sports In The World—they demand total commitment and unmatched toughness.
