The Claim
Single-set resistance training performed twice weekly for 8 weeks produces appreciable muscular adaptations in resistance-trained individuals and serves as a time-efficient alternative to higher-volume resistance training programs.
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.
Performing one set of resistance exercises twice a week for eight weeks leads to measurable muscle growth in people who already train with weights, and this approach takes less time than doing multiple sets per session.
See the scientific wording
Single-set resistance training performed twice weekly for 8 weeks can produce appreciable muscular adaptations in resistance-trained individuals, suggesting it may serve as a time-efficient alternative to higher-volume programs.
When muscles are worked under load, the force pulls on muscle fibers, which signals the cells to build more protein and add new muscle cells, making the muscle bigger and stronger.
What the research says
1 studyEven if you only do one set of each exercise twice a week, you can still get stronger and build muscle—even if you're already experienced at lifting weights. This means you don’t need to spend hours at the gym to see results.
