Garry Mod: How to move multiple ragdoll body parts and once?

I’ve seen many Garry’s Mod Machinima videos where more than body parts at once. Is this done using editing software or in Garry’s Mod? (video on thread as example) (P.S I am new to this so I don’t know which post icon is correct.) (P.SS I searched and can’t find what I’m looking for)
