#boxing : Getting a punching bag.
Punching bags don't come filled up like in pictures. Rather it's empty sack, folded synthetic skin bag. Will be delivered to you like that. And you need to fill it up with ...
Here's the point. With what? And how? The video bellow describes how to do that.
I haven't got mine yet. But you can order one from Daraz. Priced 2k BDT to something around 5k.
In short : put a foot of rag, then 4 kilos of sand pack. And then layer on like this. Sands should be packed in smaller plastic bag. Not just poured in.
Enjoy. Shall update if I happen to get mine, inshaAllah.
