As populations' life expectancies continue to increase, a major concern is whether this extended lifespan includes healthy years and improves the quality of life associated with health in old age. The disease-preventative, well-being-enhancing, and rehabilitative benefits of physical activity are scientifically established and widely acknowledged. The aim of the study was to evaluate the physical activity of adults who regularly participated in individual exercise programs in a gym. The participants consisted of 20 men, aged 41.8±10.8 years and 30 women, aged 43±10.4 years. Participants attended gym exercise programs a minimum of three times a week. The evaluation was completed in one week. The TANITAAM-120E accelerometer was used to assess physical activity. The level of physical activity was assessed based on the daily number of steps. Results indicated that the participants' average number of steps per day was lower than the World Health Organization's (WHO) recommended 10,000 steps for adults. Physical activity did not vary significantly by gender, although women exhibited a slightly higher step count. The results suggest that mere involvement in exercise programs does not necessarily contribute to achieving the recommended levels of physical activity.
