The Claim
Resistance training with equal volume performed once or twice per week for 10 weeks results in minimal muscle hypertrophy and no strength gains in trained young men, suggesting that adaptations may plateau early in this population and require novel stimuli to progress.
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.
In trained young men, performing resistance training once or twice a week for 10 weeks with a fixed volume leads to little increase in muscle size and no improvement in strength, indicating that further progress may require a change in training approach.

When trained people lift weights only once or twice a week, their muscles don't get pulled hard enough often enough to keep triggering the signals that tell the muscle to grow or get stronger. The muscle cells stop responding because the same routine doesn't challenge them in new ways.
What the research says
1 studyThis study found that even if trained guys lift the same total amount of weight, doing it once or twice a week for 10 weeks doesn’t make them much stronger or bigger. That supports the idea that their bodies stop responding to the same routine and need something new to keep improving.
