With only 2 days use, I can feel my muscles loosening from holding so much stress. Using it the first time I could feel it immediately made me engage my core muscles.
My whole family (2 adults, two teens) enjoy using this. We each have different health and wellness needs (I want lymphatic and bone density assistance, my husband wants post workout relief, teens want challenging workout) and it meets all our needs. A great item to add to our home gym.
