I have finished both Elements and Mobility and both programs are very well structured. There are millions of fitness programs online (and I have purchased dozens of them) and I couldn't finish most of them because of boredom and lack of effectiveness. Elements is actually my first online fitness which I could finish and enjoy. The movement patterns are greatly helpful to build essential mobility and strength for daily life. Most importantly, GMB staff/trainers are helpful and they answer all my questions nicely about the programs and movements. I wasn't alone when I walked through the programs. I am now on my second run of Elements and I discover something new every day! Strongly recommend!
