The point in a set where another complete repetition cannot be performed with the intended technique.
Why Failure matters
Training close to failure can stimulate muscle growth, but reaching absolute failure on every set may add unnecessary fatigue.
A practical example
Ending a machine chest press when another controlled repetition is no longer possible.
Common mistake
Confusing technical breakdown, pain or unsafe movement with productive muscular failure.
Keep the context in mind.
Training and nutrition terms describe general principles. The right exercise, intensity or food target still depends on your experience, health, goals and schedule.
Personalised coaching
Apply the principle to your own training.
A definition is useful, but your programme still needs to match your experience, schedule, recovery and goals.
