If you freeze while moving forward, try moving to the side or backward for a couple of steps.
Point to the ceiling or touch your nose — just doing something different from the original movement should be enough to break the freezing.
Use a Laser Pointer
A laser pointer can be useful to help you quickly overcome freezing, pointing the laser in front of your foot and then standing on the laser spot will usually do the trick.
Step Over Something
You can either step over a crack on the sidewalk or visualize an item to physically step over.
Use a Mini Metronome
A mini, portable metronome is useful for providing a beat which can help you avoid freezing or get you started again.
Singing or Humming
Singing or humming a song and then restarting in time with the beat can help break the freezing spell.
Counting out a rhythm or saying “one, two, three, go” can help overcome freezing.
Shift Your Weight
Shifting your weight from side to side can often help you take that first step.
Marching up and down on the spot for a few moments can help restart your momentum.
