Run same macro on multiple sheets but not every sheet

I would like to run a small VBA macro on several sheets in a workbook, but not all sheets.

I have found this code works for all worksheets but I do not want every sheet included:
ANy ideas?

Sub Dosomething()
    Dim xSh As Worksheet
    Application.ScreenUpdating = False
    For Each xSh In Worksheets
        xSh.Select
        Call RunCode
    Next
    Application.ScreenUpdating = True
End Sub
Sub RunCode()
    'your code here
End Sub
