Making a simple punching bag

Hello I have been trying to find a way to make a simple punching bag for a little si mI am making just for myself. I have done some searching on the internet and on the forums and cannot find much on how to do this. Some of the things I have seen are using hing joints or cables, but I haven’t found any more specifics. Iif anybody could give me any advice or link or information please let me know I appreciate it so much thank you very much.

There is really nobody that can help guide me with this? I guess I’ll try other forums.

aye, did you ever find a way to do this?
