New Research Unveils Muscle Growth Secrets: Why Training to Failure May Not Be Necessary

Research indicates that training near the point of failure enhances muscle growth, although its effects on strength gains remain unclear.
When engaging in resistance training, such as weight lifting, there is significant interest in understanding how approaching muscle failure—the point where you can no longer complete another repetition—impacts your results.

While research has looked at this concept in different ways, to date, no meta-analysis has explored the pattern (i.e., linear or non-linear) of how the distance from failure (measured by repetitions in reserve) affects changes in muscle strength and size.
