The moms have let go of their strollers to do "Step Ups". The RollerSizeR toning device is held in front of the Chest line, shoulders down. This keeps the chest and core still so the focus of tone is clean and less stresful on the joints. If you have bad knees you can do it on a curb. The RollerSizeR tones the arms and makes the "Step Up" exercise cleaner and less stress on back and knees. Once the moms have done ten, I sometimes have them balance into "Tea Time". The RollerSizeR® is held out in front at eye level. This works the fat under the bra and again defines the arms. They balance and focus the energy as they try to lift up the back leg as high as possible. Standing leg gets toned and the entire body is getting a serious workout.
