Use a macro like the one below
Sub InsertRows()
Dim i As Long, nRows As Integer, nEvery As Integer
Application.ScreenUpdating = False
With ActiveSheet
lastrow = .Cells(.Rows.Count, "A").End(xlUp).Row
End With
nRows = 2 'number of rows to insert
For i = lastrow To 1 Step -1
If Not IsEmpty(Cells(i, 1)) Then
Rows(i + 1 & ":" & i + nRows).Insert
End If
Next
End Sub
