Application.ScreenUpdating = False
Dim numRows As Integer
Dim r As Long
Dim Rng As Range

numRows = InputBox("How many Rows")
lastrw = Cells(Rows.Count, "A").End(xlUp).Row
Set Rng = Range(Cells(1, "A"), Cells(lastrw, "A"))
For r = Rng.Rows.Count To 1 Step -1
Rng.Rows(r + 1).Resize(numRows).EntireRow.Insert
Next r
