 This does however effectively shorten the length of rope or cord, so one may wish to stand on a raised platform of some sort if a more prolonged "rep" is desired.This can be reversed by holding it behind the body from below or above, allowing a different focus of muscles as well as a prolonged stretch for flexibility and endurance.It can be done at home also by tying a rope to a rod and attach it to weight like dumbbell or water buckets (with water filled as per your strength and ability).
