Definition
The full breakdown. What it is, why it matters, how to use it.
Form failure is the rep at which technique breaks down — the bar slows excessively, range shortens, or compensatory movement appears. Stopping at form failure (instead of grinding through ugly reps) trains the target muscle harder and reduces injury risk.

Real Questions
Question 01
Should I always train to failure?
No. Stopping 1–2 reps shy of form failure on most sets and pushing to failure only on the last set produces equal or better growth with far less fatigue.
