'Valor Fitness CB-13 Back Extension'

'The CB-13 Valor Fitness Back Extension allows the user to focus on stretching muscles while exercising muscles. Great exercise to build-up lower back muscles. Performing a reverse sit up strengthens the lower back muscles which usually are forgotten and then back pain sets in when they are used to much in such a short time.'
