The Claim
Six weeks of twice-weekly resistance training to failure using either 10 or 20 repetitions per set is associated with improvements in multi-joint strength in healthy young men, with a small but significant advantage for 20-repetition maximum over 10-repetition maximum in the lying leg curl exercise.
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 healthy young men, performing resistance training twice a week for six weeks with either 10 or 20 repetitions per set leads to increases in strength across multiple joints, with a small but measurable benefit for the 20-repetition protocol in the lying leg curl exercise.

When muscles are worked to failure with many repetitions, they use more oxygen to recover quickly, which lets them keep contracting strongly for longer. This allows the muscles to generate more force during exercises like the lying leg curl when using higher repetitions, giving a small edge in strength gains compared to fewer repetitions.
What the research says
1 studyIn young men, doing leg exercises twice a week for six weeks with either 10 or 20 reps per set made them stronger, and doing 20 reps gave a tiny extra boost in strength for the lying leg curl machine.
