The line chart illustrates the percentage of European people in four age groups who went to gym once a month or more from 1990 to 2010.
Overall, people in both four age groups went to the gym more frequently through the 20-year period. Notably, although the percentage of people aged from 25 to 34 who exercised at the gym was initially dominant, the figure of people aged 18 to 24 surpassed this proportion in 2010. While people who were over 45 always went to the gym occasionally in that period.
Looking at the second highest percentage, around 6% of people aged from 18 to 24 went to the gym at least once a month, followed by the figure for those aged 25 to 34, at nearly 5% in 1990. The figures for both two groups increased gradually by the time until 1998 when they coincided at a percentage, accounting for over 30%. After that, the percentages of teenagers rose significantly before fluctuating, reaching at 60%. Whereas, the figure for those aged 25 to 34 surged to 50% in 2010.
Turning to two other groups, the proportion of people in both two groups started at below 5% in 1990, however, people over 45 years old went to the gym less than those who aged 35 to 44 . After that, the former grew significantly until 2006 before reaching its peak at 40%. Similarly, the latter increased steadily and surged at over 20% at the end of the period.
