Of course there are some risks overdoing these kinds of drills.

Although I love a gorgeous toe-extension line in artistic activities, this sort of technique, commonly used with gymnastis coaches can be quite destructive to the extensor tendons and stabilizing ligaments of the foot and ankle.
Often, relying on this method can easily lead to ankle and foot instability, premature osteoarthritis, and what is known colloquially as “turf toe” in athletes.
This method discussed by Ms. Mary-Lee Tracy relies on brute force, ergo passive plantar flexion as opposed to active plantar flexion (which athletes are using mid-maneuver).
I encourage techniques that involve active extension and strengthening, rather than brute force, to avoid unnecessary damage to athletes’ feet and ankles.
