in boxing i used to be scared to spar guys who were bigger because i would get my butt kicked . then i learned about timing and proper technique and gained more confidence when i was able to hit them back i believe this story please tell me ore well the first gym i trained at was pretty brutal ... nobody held back punches , we would pretty much try to knock each other out such a manly thing to do dont you agree ? it was fun and now i 'm a beast haha
The size and strength disparity with larger opponents caused the feeling of fear.
