What this claim means

After eight weeks of practicing lifting one heavy weight repeatedly, untrained people get just as strong as those doing many lighter lifts, even though their muscles do not grow larger.

See the technical phrasing

Eight weeks of practicing the one-repetition maximum (1RM) strength test produces strength gains in untrained individuals that are equivalent to those achieved through high-volume resistance training, despite the absence of measurable muscle hypertrophy in the 1RM practice group.

Why this might work
Verified
based on 1 study

Practicing lifting the heaviest weight possible trains the brain to send stronger and more coordinated signals to the muscles, allowing more muscle fibers to fire at the same time and with greater speed, which increases force output without making the muscles bigger.
