I've got this habit with my rear hooks lately, but I dont know if it really makes a big difference. When I throw the rear hook, i tend to bend my arm. Picture it like this. My hand is in front of my neck, and my elbow is up towards my face, so it's almost like im curving it downward. I havent got into heavy sparring yet so I dont know of this is a bad habit or not. If it's not gonna affect anything then I'm fine with it, I just wanted to know if it needs to be fixed. I'm very new to boxing so forgive me for stupid questions.
