YOU probably have tight calves and restricted mobility in your feet. Most of us do- you are not alone! Use this simple stretch with the half roller to lengthen your back line. This will help you walk with less restriction and keep you from shuffling along. BY THE WAY! We have this prop in all areas of the studio. Help yourself to this stretch anytime you are at Body Dynamics or buy one for your personal use at home! Walking without pain is wonderful! Enjoy!
