Gmod Blender: How to place back mesh into it's original place.

[Jooby1]

I am weight painting a model.

I am dragging the front of the foot upwards to weight paint the areas that aren't weight painted.

After doing that I can't get it onto it's original place. I tried repeat but it didn't work.
Is there any way to put it back into it's place without undoing what I weight painted.

Thanks!

Select the bone and press alt+g or alt+r if you rotated it
