The Claim
Twelve weeks of resistance training consisting of 8 exercises performed at 10–15 repetitions maximum leads to significant increases in upper limb strength (27–37%), lower limb strength (16–22%), lean soft tissue (5.6–8.8%), muscle quality (10.5–25.2%), and IGF-1 levels (7.1–10.1%) in untrained healthy older women, with no difference observed between performing one or three sets per 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.
If older women who aren't used to working out do 12 weeks of strength training—using 8 exercises and doing 10 to 15 reps each time—they’ll get noticeably stronger in both arms and legs, gain muscle, and improve key health markers, whether they do one or three sets per exercise.
See the scientific wording
Twelve weeks of resistance training using 8 exercises at 10–15 repetitions maximum significantly increases upper limb strength by approximately 27–37%, lower limb strength by 16–22%, lean soft tissue by 5.6–8.8%, muscle quality by 10.5–25.2%, and IGF-1 levels by 7.1–10.1% in untrained healthy older women, regardless of whether one or three sets are performed per exercise.
What the research says
1 studyThe study found that older women who did resistance training for 12 weeks got stronger and built more muscle, no matter if they did one or three sets per exercise, just like the claim says.
