You used to be able to find ads for ‘The Reg Park Muscle Builder Set’ on the back of Reg’s magazine “The Reg Park Journal.” If you saved up your allowance for one of these sets, you got quite a haul: a 10-strand cable exerciser, a wall pulley attachment, a head strap, foot stirrups, two hand grips (for a mighty, he-man grip) a cable exercise and rowing machine and, of course, several free courses to show you how to use it all.
