“In the Fire Service, we often lift patients from awkward spaces such as a bed or a bathtub. Over my 29-year career, all that off-center lifting left me with chronic back pain. I had resigned myself to a lifetime of pain pills in order to sleep. Then I discovered MOSSA. The strength-based training, as well as the emphasis on flexibility and core, has produced a second chance at life without pain or medication.”

"A friend recommended MOSSA On Demand about 2 years ago, specifically Group Power, and I was quickly hooked. All I had were hand weights and resistance bands, but since then I've added a step and the MOSSA barbell and dumbbell sets...I love that I can be a positive role model for my kids and be a witness that you can keep moving no matter where you are physically or mentally. And I credit MOSSA for that."
