The given line graph illustrates the proportion of people in four age groups who visited the gym at least once a month from 1990 to 2010.
What is most striking when looking at the data is that all four age groups exhibited an upward trend in gym over the years shown, albeit to varying degrees. Notably, the 18-24 age group had surpassed the 25-34 age group to become the most frequent gym-goers by the end of the period.
In the initial year, the predominant age group was those aged 25-34, representing 15% of gym-goers.This was followed by the figures for 18-24 and 35-44 brackets, at around 10% and 5%, respectively. In the last place stood those aged over 45, as a mere 3% of them attended the gym .
In the subsequent years, the proportions of gym-goers aged 25-34 and 35-44 experienced a generally upward trend with some fluctuations, reaching approximately 50% and 40% by 2010, respectively. In a parallel trend, the figure for the 18-24 age group rose considerably throughout the period, ultimately soaring to a peak of 52% in 2003. Unlike the other three age ranges, the data on people aged 45 and over witnessed a gradual yet modest growth, with only 22% of individuals attending the gym by the end of the timeframe.
