After fist-punching his way through the U.S. Army's basic training program, bobbing and weaving through an amateur boxing career, and drop-kicking every last test that stood between him as his law degree, the poet-warrior Edward Rush opened a commercial gym in Washington, DC. He soon grew tired of folding towels for patrons who only wanted to use his gym as a place to read magazines or watch TV while they jogged, so he closed up shop, moved to NYC, and opened a personal-training gym and fitness laboratory. There, he earned the nickname "The Mad Scientist" for his grueling, inventive, and rewarding training method, called IFS.

For a quick, intense workout, students can turn to the gym's CrossFit classes. CrossFit incorporates a fusion of strength and cardiovascular conditioning exercises that grant bodies with sculpting, toning, and endurance-boosting benefits in less than an hour. In fact, many members hustle through the retinue of handstand pushups and Olympic-style power cleans on their lunch hours via the gym's power lunch program, which includes a paleo-diet meal delivery when the workout is completed. Whether over lunch, early in the morning, or at the end of an office day, students can attend classes up to six days a week and retire to well appointed locker rooms equipped with showers, towel service, and complimentary grooming products.
