The graph illustrates the proportion of individuals among various age groups who attended fitness centers at least once a month during a 20-year period from 1990 to 2010. Overall, it can be seen that the percentage of gym-goers steadily increased across all age groups over the 20-year period. In 1990, the older age group had the highest attendance, but by 2010, the younger generation had surpassed them, leading in gym participation.
In 1990, approximately 5% of 18-24-year-olds frequented the gym monthly, compared to slightly lower percentages for the 25-34 (8%) and 35-44 (7%) age groups, and only 2% for those aged 45 and above. Following this, the youngest age group experienced the most significant rise in attendance, peaking at around 55% in 2006 before stabilizing just below that figure by 2010.
Looking at the other three age groups, the 25-34 cohort displayed a steady increase, reaching approximately 50% by 2010. Similarly, the 35-44 group showed consistent growth, albeit at a slower rate, rising from 7% in 1990 to about 40% in 2010. In contrast, the 45 and over group exhibited the lowest gym attendance rates. Though participation saw modest growth, it only reached around 21% by 2010, significantly trailing behind the other age groups.
