How do i "lock" multiple layer components of the genesis body forms?

So Im new to Daz Studio and recently purchesed the anatomy pro pack and Im having a quite a time tring to get the skeleton and the body to move in unison. The skeleton always jets out at some point. how do I remedy this?

This https://www.daz3d.com/anatomy-4-pro-bundle ? It's not for genesis, and although the skeletons and organs can be AutoFitted to Genesis they will distort. The set does include the Victoria and Michael base figures (and morphs) which are what the skeleton and organs are designed to work with - you can then fit the extras to the figure and when you pose the figure the skeleton/organs will follow. To fit the items, select them and use the Fit to button in the Parameters pane or right-click and select Fit <name> to, then pick the base figure in the dialogue.
