Speed bag loose help?

Question

My speed bag is mounted on my wall with the everlast mount set up. I nailed a piece of plywood against the wall and then nailed the platform with the speed bag onto that. It seems everytime I hit it, it shakes. The bolts are as tight as I can get them. I've tried putting weights ontop but they don't really work. I did see a set up with a wire connected tothe ceiling above the platform holding it up. I need advice. Thanks.

Answer 1

You might need to get a better speedbag platform.

Answer 2

try another wall. it looks like that one is already messed up. good luck
