Hi, i have been boxing for about 2 years and if you were to see me on the heavy bag you would think i would be a future world champion. but i have a big problem i may have the thing called gloves shy because i fought someone that was alot bigger than me and 20 years older, i just turned 14. I come from a family of boxers and they say just wait until my muscles grow bigger i have about 13 inch arms. i think my only problem is i always fight people alot bigger, i am 5-7 about 1 47 in great shape. tell me what i can do to get over this.
