The given line chart depicts the proportion of Europeans across four age groups who frequented the gym at least once a month over a 20-year period from 1990 to 2010. Overall, all four age cohorts experienced a steady upward trend throughout the two-decade timeframe. The 18-24 age group registered the highest attendance rates for the bulk of the period, while those aged above 45 remained the least frequent gym-goers throughout. Regarding the two younger demographics, in 1990, the attendance rates of the 18-24 group and the 25-34 group were nearly identical, standing at 7% and 8%, respectively. The percentage of 25-to-34-year-olds experienced a steady and uninterrupted rise throughout the period, reaching 51% in 2010. In contrast, the figure for the 18-24 age cohort grew more steeply from 1998, surpassing that of the 25-34 age group at around 46%, before peaking at 58% in 2006 and remaining at this level until 2010. Regarding these two demographic groups, the gym attendance rates of those aged 35-44 and over 45 stood at 5% and 3%, respectively, in 1990. The 35-44 age cohort showed a relatively gradual increase for the bulk of the period, reaching approximately 26% in 2006, before accelerating sharply to 40% by 2010. Meanwhile, the 45+ group followed a similarly modest but consistent upward trajectory, though at a considerably slower rate, ultimately reaching only 22% in the final year.
