Should I refrain from hitting the heavy bag before I get a boxing coach? I heard that doing so will build bad habits. The boxing gym where I live is still closed due to COVID-19. I mean... I really do wonder... There's some good stuff in ExpertBoxing.com. Can't I just buy some of their DVDs and self-teach? Obviously, without a coach, training partners, and sparring partners, I won't get anywhere. But what about merely learning proper technique?? I have a working camera with a tripod. Still, I'll likely won't go that route. But I do wonder if it truly is a bad idea.
