How do i make a Weight Life animation?

Hello devs, how are you?
I need to develop a weightlifting animation in roblox but I don’t quite understand how to do it. I’m using Moon Animator 2 to perform the animations but it’s not working as expected, could you give me tips on how to fix it?

You have a motor6d attaching the hand and the prop together, it is working as expected. If you could clarify a true issue I might be able to help, but observing the video, everything looks fine.

it’s because I don’t know where to start, what’s the best option to be able to do this type of animation?
