                                          EXERCISE IN EXACTLY 4 MINUTES PER DAY!

                                                                       $14, 615

      TIME IS IT. Over 92% of people who own exercise equipment and 88% of people who own health club

memberships do not exercise. A 4-minute complete workout is no longer hard to believe for all the people who

have bought our excellent Range for 30 days end up buying it, due to the health benefits experienced during that

tryout and the ROM performance score that tells the story of health and fitness improvement. At under 20 cents

per use the 4-minute Rom exercise is the least expensive full body complete exercise a person can do. How do

we know that it is under 20 cents per use? Over 90% of Rom machines go to private homes, but we have a few

that are in commercial use for 12 years and they have endured over 80,000 uses each, without need of repair.

The ROM 4-minute workout is for people from 10 to over 100 years old and highly trained athletes as well. The

ROM balances blood sugar, and repairs bad backs and shoulders. Too good to be true? Get out free video and

see for yourself. The best proof for us is that 97% of rentals become sales. Please visit our website at www.
