I have been dealing with a severely strained back muscle for a little over 4 years now. I have tried yoga, incorporating more resistance training into my exercise regimen, random chiropractic stretches; NOTHING HAS EFFING WORKED. But, this is. I've only been on it a week, and I already have movement restored on my left side where the back injury lies. My hip does not hurt when I bend any longer, and my balance is being restored after 2 years of leaning to one side. Many thanks Alex. Everyone has their own journey, and I see the negative reviews. All I can say is that this may not be for everyone, but some do benefit. Gratitude, again, for this program. (No, I'm not a bot or paid reviewer.)
