Have you ever wondered how many people actually use their gym memberships? According to a report from the International Health, Racquet & Sportsclub Association (IHRSA), more than 45 million health club members made an average of 102 visits to facilities in 2009. Those members earned about $75,000 per year and paid an average of $41.47 per month for gym membership; their average age was 40.7 years.

“[With] less discretionary income, consumers now expect to pay a bit less for their memberships, but they tend to use them more,” said Melissa Rodriguez, IHRSA’s research manager.

The information was printed in The IHRSA Health Club Consumer Report: 2010 Health Club Activity, Usage, Trends & Analysis.
