General strength and fitness
As we age we lose approximately 1% of muscle mass per year from the age of 40. At 60 we have about 20% less muscle mass than at age 40. It is very important to maintain muscle strength. Weakness can lead to falls and fractures, inability to compensate when out of balance, difficulty getting out of bed or a chair, getting up stairs, fatigue and pain. We all want to live a long but also active life. The vast majority of nursing home admissions are due to weakness, falls, and mobility issues. One could argue that as we age strength and fitness through regular exercise is more important than at any other age.
