Form is shape. It is typically max range of motion shape. It is supposed to be flexible in application.
If you don't get to the point of application where you come to understand the flexibility of the form shape, then you need to practice more.

Forms should be at the end of training, not the beginning.
Basic stance, punches, kicks, throws and locks first, then drills and apps, then spar, then when proficient, re-communicate all through forms.
