Hide Rows On All Worksheets Meeting Criteria

I have the following code that works well on a single worksheet

Sub hide()
For Each rw In ActiveSheet.UsedRange.Rows
If rw. Cells(3) = 0 And rw.Cells(5) = 0 And rw.Cells(6) = 0 Then rw.Hidden = True
Next rw
End Sub

However I want it to run on each worksheet in the workbook when I run the macro. I tried this but it seems to loop continuously on the first worksheet. When I press escape the line "next row" is highlighted in yellow by the debug in the VBA Editor.

Sub hide()
Dim ws As Worksheet
Dim rw
For Each ws In ThisWorkbook.Worksheets

For Each rw In ActiveSheet.UsedRange.Rows

If rw.Cells(3) = 0 And rw.Cells(5) = 0 And rw.Cells(6) = 0 Then rw.Hidden = True
Next rw

'Next ws
End Sub
