2018 updated version now contains even more Fitness on the Move(TM) exercises in this newly expanded book. Time is the #1 reason why people don't exercise. The #2 reason is lack of access to a gym. With the ISOfitness(TM) system of Fitness on the Move(TM) There are no more excuses. You can literally workout anytime, anyplace, everywhere, thanks to the ISOfitness(TM) exercise system of advanced isomeric exercises, combined with the powerful Iso-Bow(R). The advanced isometric exercises of the ISOfitness(TM) system have been scientifically proven in thousands of independent experiments to be superior to traditional exercise methods. We've tried and tested the Fitness on the Move(TM) system by performing full workout routines in a Zero Footprint Workout Environment(TM) as passengers in cars, on trains, in cramped airline seats, on mountainsides, on beaches, and once even on the deck of a ship in a storm. The ISOfitness(TM) system of Fitness on the Move(TM) allows a full-body workout in the smallest space humanly possible thanks to our Zero Footprint Workout(TM) concept. With the Fitness on the Move(TM) system you never need to miss a workout ever again. Required Equipment: 2 x Iso-Bows - available on Amazon.com
