When performing low-weight resistance exercises, stopping just before complete muscle fatigue results in the same muscle growth as pushing until complete exhaustion.
See the technical phrasing
Training to volitional discomfort (stopping 1–3 repetitions short of failure) during low-load resistance training produces the same degree of muscle hypertrophy as training to momentary muscular failure.
When lifting light weights close to exhaustion, muscle fatigue builds up from repeated contractions, forcing the nervous system to recruit stronger muscle fibers that were not used at first. These stronger fibers are more capable of growing, and their activation triggers signals that cause the muscle to add new contractile units, leading to muscle growth.
