Progressbar is an element of the user interface that indicates the progress of an operation, in this action you are doing there is no action that needs Progressbar.

An example where you can use Progressbar is the use of Asynctasks to load API data, download image and so on... unless to simulate the Progress you use some postDelayed setting a time to simulate a delay in the screen transition.

 btiniciar = (Button) findViewById(R.id.btiniciar);
    btiniciar.setOnClickListener(new View.OnClickListener(){
      public void onClick(View v) {

                //MOSTRAR PROGRESS
                final Handler handler = new Handler();
                handler.postDelayed(new Runnable() {
                    @Override
                    public void run() {
                     //ESCONDER PROGRESS
                       Intent it = new Intent(MenuActivity.this,LoadActivity.class);
                       startActivity(it);
                       finish();
                    }
                }, 2000);
      }
    });
