Older People Benefit From Progressive Resistance Strength Training

Yep - training is what it is all about. Not "exercise."

"Progressive resistance strength training not only helps older adults become stronger but also makes their everyday life easier, a Cochrane Review suggests.

Muscle strength decreases naturally as people age. This reduction in muscle strength could affect older adults carrying out daily activities. Progressive resistance strength training is a type of strength training that uses free weights, exercise machines, or elastic bands to strengthen muscles. Key to this type of this (sic) exercise is adjusting the resistance, or weight, according to the person's progress. This exercise can be prescribed to help older adults gain the strength necessary to carry out everyday activities such as walking, climbing stairs, bathing or doing housework."

Go for it if you value your independence.
