REZULTR® is simple to use by reviewing our detailed exercise list but we highly recommend that you seek professional consultation to get the full effects of this state of the art device. If you are injured we highly recommend that you seek medical advice to ensure that you are healthy enough to exercise. After being cleared by a doctor we recommend that you use a trained and licensed Physical Therapist to ensure proper technique and for best results. If you are not injured but are just trying to get in better shape then we recommend that you first get medical advice that you are healthy enough to exercise. Once you are cleared to exercise we recommend that you contact a certified REZULTR® instructor for best results.  You can contact us at info@rezultr.com and we will give you the name of the closest REZULTR® instructor.
