Stage blocking is possible in a variety of classrooms, but may require some adjustments.  Consider rearranging chairs to allow for greater movement and connection.  Especially in large lecture halls with stadium seating or a balcony, it is helpful to assess how much you can use the space without interrupting students' line of sight.

Consider recording yourself teaching for later review.  Most instructors report that they learn a great deal about their use of space, timing, gestures, and habits of speech.

If you realize that you are in the habit of making unwanted movements, it may be easier to find an acceptable alternative than to try to eliminate it altogether.

Professor McGraw recommends that you strategize about your movement in advance, even marking your lecture notes for blocking.

As you plan your presentation, it is helpful to contemplate the timing of your movement — just before, during, or after a significant statement.  Will your movement highlight or distract from a particular statement?  Some practitioners have found that moving just before usually works best to highlight a particular statement.
