Want to add additional columns to attached macro

Hi,

Can someone help please. I don't know how to add addtional columns to the attached macro. At the moment when I run macro it provides me with one column of data with a heading. Want to add an extra four columns. The titles of columns can be col2, col3, col4 and col6.

Many thanks.

Sub ListTraining()
Dim LastRow As Long, i As Long, StartRow As Long, NameCol As Integer
Dim ISh As Worksheet, OSh As Worksheet, j As Long
StartRow = 2
NameCol = 1
Set ISh = ActiveSheet
LastRow = ISh.Cells(Rows.Count, NameCol).End(xlUp).Row
Application.DisplayAlerts = False
On Error Resume Next
Sheets("Need Training").Delete
On Error GoTo 0
Application.DisplayAlerts = True
Worksheets.Add(After:=Worksheets(Worksheets.Count) ).Name = "Need Training"
Set OSh = Sheets("Need Training")
OSh.Cells(1, 1).Value = "Training overdue for Manual Handling"
j = 1
For i = StartRow To LastRow
If IsEmpty(ISh.Cells(i, NameCol + 1).Value) Then
j = j + 1
OSh.Cells(j, 1).Value = ISh.Cells(i, NameCol).Value
End If
Next i
OSh.Columns(1).EntireColumn.AutoFit
End Sub
