Have you ever thought whats in an actual heavy bag or how it's made. This is a question that continually in my messages. I've never actually had the opportunity to watch a complete heavy bad filled until this video. After asking a few other professional fighters, they haven't either. I was told that back in the day the bags were filled with straight sand. I'm very curious if they still make heavy bags with sand.
If you have questions like this or anything else fight related or not, post it or message me so i can get to getting it for you if you laying down what im picking up...
