Anytime Fitness, Delaware

No matter what time it is, someone somewhere is working out at Anytime Fitness. More than 1,800 franchised clubs across the country fling open their doors 24 hours a day, revealing gaggles of equipment designed to make working out less of a chore. Rows of Lifestyle Fitness treadmills and Precor ellipticals mounted with cardio TV let guests work out and catch up on their favorite shows, and Expresso game cycles blend the excitement of playing video games with the exercise of riding your bike to a friend's house to play video games. In addition to copious supplies of free weights, the gym also stocks a Koko all-in-one training machine. The futuristic robot-butler-esque equipment stores individual workout plans and progress on a chip so exercisers can track their performance over time on the built-in monitor.
