Which of the following is NOT an indicator of frailty?

Improved exercise endurance is not an indicator of frailty. In fact, frailty is typically characterized by a decreased ability to perform physical activities, leading to fatigue or a decline in endurance. Indicators of frailty often include unintentional weight loss, which signifies a decrease in overall health and body mass, poor grip strength that reflects muscle weakness, and slowing of movement that indicates reduced functional ability and mobility. These factors collectively point towards a state of increased vulnerability and reduced resilience to stress, which are hallmarks of frailty, making improved exercise endurance an antithesis to such indicators.
