I stumbled upon GMB a few months before the pandemic, and boy was that a good thing. Even before lockdowns began, I had progressed from minimal hip mobility to being able to stand from a squat with my heels up by going through the legacy Elements program. Since then, GMB has come out with several new programs and a new way to access most of them, Praxis, that has made it even easier (and I still have access to Elements several years later, so a great investment), and with more attention to modifications for those of us who are not already olympic gymnasts. Even so, I still need to work on my self-discipline, because I will fall off the wagon from time to time and need a kickstart to get back in the habit, so I have been ecstatic to participate in two Live programs (Elements and Mobility) and look forward to the day when Facebook is no longer required for such events. At any rate, I'm still amazed that I hadn't lost most of the gains I'd made when falling off the wagon, such as being able to stand from squat, but that may be because once I could squat and stand, I'd use the ability "in the wild" whenever I could, like picking up something off the floor or whatever. Highly recommend GMB for gaining or regaining mobility as well as for those more athletic types fine-tuning the already superior mobility they already have--there is definitely something for everyone, and getting started, I'm confident, is something everyone will wish they had done sooner.
