Since the early 1970's, a quiet, yet effective revolution has been taking place in the realm of exercise science. 

Starting with his invention of Nautilus® equipment, Arthur Jones gave birth to what is now known as High Intensity Training, or HIT.  This form of training places the emphasis on brief, infrequent, yet high effort workouts, as opposed to the longer, more frequent, lower effort workouts more commonly followed by the general public.

Mr. Jones' innovations eventually lead to the modern day fitness center.  After a decade of dominance with clubs using his methods and brand name exclusively, the fitness mainstream eventually diversified to other equipment such as bikes, treadmills, stair climbers, and elliptical machines.

What was once 24 HOUR NAUTILUS® , eventually became 24 HOUR FITNESS® , with the blink of an eye.  However, no one has ever credibly challenged the results of Mr. Jones' original training concept. 

In its infancy, HIT workouts were considered to be effective when being performed two or three times per week with user defined workouts and traditional weight stack equipment. 

Tone in 12™ advances the revolution with our Isofitness™ training program, which allows you to replace as many as three traditional workouts per week with just one 12-minute session.

Isofitness™

First developed by exercise theorist/author Greg Kelly in the year 2000, Isofitness™ has evolved over the years as a program originally requiring 90 minutes of weekly exercise.  This number moved downward over the years to 30 and 20 minutes, through continued refinement of his methods and equipment.

Today, Greg has achieved a total fitness solution at TONE in 12™ in just 12 minutes per week.

Greg has also developed a low cost, modified version of TONE in 12™ for training at home.  Total time invested will vary depending on available equipment, instruction, and training skill.
