I've been following these guys almost since they started. The exercises and nutrition information are all research based. There are lots of choices and you can move at your own speed with all of them. They are supportive within the programs and there is a support page on Facebook for those who want it. They are responsive and helpful if you email them a question or engage the question feature on the website. Love being able to follow along in my living room. I am 73 and moving and sleeping better since I joined.
