The Claim
In adults aged 60–85 years, a 3-month program of resistance training performed three times per week at 75% of one-repetition maximum, with four sets of 15 repetitions per exercise, is associated with improvements in lean mass, lower limb strength, and cardiorespiratory function, as measured by sit-to-stand performance, handgrip strength, and spirometry, compared to no intervention.
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 adults aged 60 to 85, a structured resistance training program performed three times weekly for three months leads to measurable increases in lean body mass, leg strength, and lung function compared to no exercise.
See the scientific wording
In adults aged 60–85 years, a 3-month program of resistance training performed three times per week at 75% of one-repetition maximum, with four sets of 15 repetitions per exercise, is associated with likely improvements in lean mass, lower limb strength, and cardiorespiratory function, as measured by sit-to-stand performance, handgrip strength, and spirometry, compared to no intervention.
Lifting weights repeatedly makes muscle fibers tear slightly and then rebuild thicker and stronger, which increases muscle mass. This also trains the nerves to activate more muscle fibers at once, making movements like standing up or gripping stronger. The muscles use more oxygen and energy during and after exercise, which improves breathing capacity over time.
What the research says
1 studyOlder adults who did strength training three times a week for three months got stronger, gained muscle, and breathed better — even without protein shakes. Doing nothing didn’t help as much.
