Recent research has shown the benefits of strength training to include reduced risk of stroke, heart attack and diabetes. Specific to older adults, resistance training can reduce sarcopenia (age related muscle loss) and fall risk as well as help to maintain bone mass.
This article cites research concluding that “resistance exercise promoted better anti-inflammatory balance and physical performance simultaneously with an increase in cognitive profile in older women with cognitive impairment”.
Aim for 3-4 strength training sessions per week and choose exercises and weights that provide a challenge. If you’re just starting out, check with your doctor & consider body weight exercises, light dumbbells or resistance exercises or even household items.
A session or two with a trainer is a great idea to ensure you’re choosing the right weights & that your form is on point.
