class Import  

def import_workouts(rows)
   CSV.foreach(@import_file_path, {headers: true}) do |row|
      attributes = row.to_hash
      workout = Workout.new(attributes)
      
      unless workout.save
        workout.save(validate: false)
        workout.update_column(:status, :needs_revision)
