Im 15 i just started boxing, i weight around 145, im pretty stout, i bench 205. i started boxing a few days ago, its all pretty good, but my left arm seems to be having trouble. it feals really weird to jab, it feals like its not making very much power, how can i get my arms trained where i can punch strait out and go strait abck to defennce its just not working
the best thing i can say to you is just keep training.and if its not that then it might just be you dont know your jab is hard,or it might be that it aint hard but it will get better the more you train.
sorry i couldnt help you
