Listen, your height and weight are just fine. We've seen many of these kind of threads over the years which is normal, but this is the deal. Don't sweat that stuff.

If you want to box the most important thing is your ability to get your ass through the boxing gym doors. From there on in your determination and how much you find you like/love it will set the course for where you and boxing end up.

Good luck and welcome to Saddos.
