Training to failure produces greater hypertrophic adaptations than training not to failure, but only when total volume is not equated; when volume is equated, the two methods yield equivalent results.
You do not need to train to failure on every set to maximize muscle growth. If you train close to failure but stop before, you can achieve similar hypertrophy as long as you match the total volume (sets x reps x load) of a failure-based program. Training to failure increases recovery time and may not be comfortable for beginners.

Notwithstanding, the same authors observed that all these differences disappeared when the volume was matched, making the two training methods equivalent.
Why this rating
Supported by two meta-analyses cited in the review.

More from this paper
- Resistance training protocols must report within-exercise variables beyond load and repetitions—including failure status, range of motion, time under tension, and attentional focus—to accurately determine the training stimulus.Good
- High loads (>60% 1RM) are superior to low loads for maximizing strength gains, while both high and low loads can produce similar hypertrophy if performed to failure.Good
- Full range of motion (ROM) produces greater strength gains in full ROM tasks and greater hypertrophy in specific muscles (e.g., gluteus maximus) compared to partial ROM, although partial ROM can be used to overcome sticking points.Good
