Every set does not need to go to failure
No. Hard sets matter, and getting close to failure can help hypertrophy, but the evidence does not turn momentary failure into a requirement for every set.

A 2021 systematic review and meta-analysis found comparable hypertrophy between failure and non-failure training when volume was equated, with no overall strength advantage from failure. Proximity-to-failure reviews keep effort as an important variable, but the dose-response is noisy. A separate acute-fatigue meta-analysis found greater immediate fatigue, perceived effort, metabolic response, and muscle-damage markers after failure training.
What to do instead
Keep most working sets hard and controlled, often with one to three clean reps left. Use true failure selectively on stable, lower-risk accessories, final sets, or short phases. If performance drops, joints ache, technique changes, soreness lingers, or the next session gets worse, reduce failure work before blaming motivation.
