“A Finnish study demonstrated that people over 65 years of age enjoy better overall health after taking up resistance training at least once a week. Interestingly, the participants did not need to work out very often to enjoy the benefits of physical exercise. Once-a-week sessions of resistance training sufficed to enhance various aspects of their health throughout the trial. Bi-weekly workouts achieved the best effects. Furthermore, people with poorer health derived the greatest amount of health benefits from physical exercise. Older people who did resistance training every week experienced increases in muscular strength. They also displayed improvements in their cardiac health, cholesterol and inflammatory levels, and systolic blood pressure. Last but not least, their mental health also improved. “We found that individuals who were close to having high blood pressure, high cholesterol, high blood glucose, or high levels of inflammation improved the most after our 9-month training program,” remarked University of Jyvaskyla researcher Dr. Simon Walker. “Training two or three times per week didn’t provide greater benefit in these individuals.”
