Calm your mind and imagine for a moment - what physical activity in real life can be performed in this position. For what purpose would one take this position - what would be the reason?
Thus, your imagination gives purpose and direction to the movement, and it becomes justified, it turns into a logical action. Once you have found the story behind your "frozen" figure - UNFREEZE it - Develop the subsequent movement as a natural expression of a justified action.
Variations
Once you become familiar with this exercise, try to add a condition/quality to your justified action. For example, you are not just jumping to catch an apple, but your legs hurt, and you must jump many times to reach the apple, or you are freezing, or you are very hungry, you are enormously big, and so on. Think how the condition/quality is influencing your physical movement and the story behind the justified action.
