Did You Know? There are twice as many gyms in the United States as there are McDonalds restaurants. If it looks like there is a gym on every corner in most town, its more likely because there is. There were over 30,000 gyms in the US in 2012 in comparison to about 14,000 McDonalds. That gap is widening, too. Growth of fast-food restaurants has slowed since 2005 but the number of gyms has increased by 10%.
