what muscles or parts of your body help you bowl fast? what can i do to increase my speed?
i'm fairly well built (179cms/68 kgs; slim-semi muscular, seventeen years old). take that into account.
i think if i compared my current speed to everyone my age, i'd be in the top 70%. but i have never been speed-gunned, so i don't know details.
