Doing strength training three times a week for three months can help improve muscle size, strength, belly fat, cholesterol, blood sugar, and overall metabolic health in women around 69 years old who are otherwise healthy.

What we've found so far is that 12 weeks of resistance training three times a week may improve muscle, strength, and metabolic health in older women. The evidence we've reviewed leans toward benefits in muscle size, strength, belly fat, cholesterol, blood sugar, and overall metabolic health for healthy women around 69 years old [1]. Our analysis of the available research shows that regular strength training over three months is linked with positive changes in several aspects of health. We looked at 32 supporting assertions and found no studies that contradicted this pattern [1]. These findings suggest that three weekly sessions of resistance training may help increase muscle mass and strength, which can support mobility and daily function. At the same time, improvements in belly fat, blood sugar control, and cholesterol levels point to potential benefits for metabolic health [1]. We want to be clear: this is what we’ve found based on the current evidence. We don’t know if these results apply to all older women, especially those with chronic health conditions, since the data focuses on those who are otherwise healthy. Also, we can’t say how long these benefits last after training stops, or whether more or less training would work better. It’s important to note that we’re not claiming this routine “proves” or “definitely causes” these changes. We’re reporting what the evidence we’ve reviewed shows so far. The number of supporting assertions is high, and none refute it, but science is ongoing. As more data becomes available, our understanding may evolve. Practical takeaway: For healthy women in their late 60s, doing strength training three times a week for three months might help build muscle, get stronger, and support key health markers like blood sugar and cholesterol.
