About Us

In the early 90’s, after suffering several exercise related injuries and feeling generally worn out, Adam Zickerman was struck by the notion that brief, intense exercise performed just once a week could yield equal and, possibly superior results compared to his five-day-a-week exercise routines.

For five years, Adam immersed himself in the exercise sciences, and recruited his family and friends as guinea pigs while he developed his exercise protocol. In 1997, he opened his first InForm Fitness – a 300 square-foot space, in a dank basement, with five pieces of used equipment.

The big break came in November that same year when this ‘radical’ workout was featured on the front page (Science section) of the New York Times. This resplendent publicity led InForm to open its second location in midtown Manhattan during the summer of 1999.

InForm’s ecstatic, and quickly growing, client base fueled more national publicity and a book deal with HarperCollins. In 2003, Adam and friend Bill Schley, co-wrote, Power of 10: The Once a Week Fitness Revolution. The book became a NYT’s bestseller and Adam was thrust into the limelight appearing regularly on the local and national media scene extolling the virtues of the Power of 10 workout.

Currently, InForm Fitness’s headquarters is still housed at the same Midtown address, although it’s been expanded to 4,000 square feet and serves over 300 clients weekly. In recent years, InForm has opened 5 additional locations – Los Angeles, CA., Leesburg, VA., Boulder, CO., Denville, NJ., Port Washington, NY. – and launched a mobile gym; a 27-foot bus with retrofitted equipment available to train people at their home or office.
