The Claim
In resistance-trained individuals, an 8-week training protocol that increases load while maintaining constant repetitions results in slightly greater gains in maximal lower-body strength (1RM squat) compared to a protocol that increases repetitions while maintaining constant load.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Over eight weeks, resistance-trained people who progressively lift heavier weights with the same number of reps gain slightly more maximum strength in their squat than those who do more reps with the same weight.
See the scientific wording
In resistance-trained individuals, increasing load while maintaining constant repetitions leads to slightly greater gains in maximal lower-body strength (1RM squat) than increasing repetitions while maintaining constant load over an 8-week period, though the difference is small and uncertain.
When lifting heavier weights, the nervous system activates more muscle fibers at the same time, especially the strongest ones, which trains the body to produce more force in a single effort. This makes it easier to lift the heaviest weight possible.
What the research says
1 studyThis study found that lifting heavier weights over time might help you squat a little more weight than doing more reps with the same weight, but the difference is so tiny it might not matter in real life.
