Why the changes to the popular 5BX program?

The original 5Bx program was a good exercise program that was created in the 1950’s by BillOrban and the Canadian air force. The 5BX program sold over 20 million copies between the1950’s – 1980’s and at this stage a lot of people were saying that the exercises were not safe touse. We have based the Goodbye Couch! Fitness exercise program on the original programchanging the potential dangerous exercises and instead of doing as many repetitions in aminute we have changed it to total repetitions in a row.
