Health Tip

As people age, they naturally lose muscle mass, so it’s important to strength train to stay strong. If there’s only time for one exercise, do a set of squats, experts say.

Squats strengthen all of the muscle groups in legs, including the calves, quadriceps, hamstrings and glutes, as well as muscles in the lower back and core. Those muscles provide the foundation for most activities of daily living, such as climbing a set of stairs and simply standing up from a chair.
