I bought GMB Fitness's Elements because I wanted to add something different into my fitness routine, learn some new ways to move, and make my mid-40s body feel younger. I'm really glad I did. Elements steadily strengthens and increase the range of movement of parts of the body that other routines don't reach, and since buying it I have bought several other GMB packages. I expect to be doing them for many years to come. The structure of the sessions took a bit of getting used to at first, as they are not led by a sweating, pep-talking instructor, but are calmly introduced and then leave to you to practice the same move for a few minutes. This has grown on me, though, as a different and focused way to do a workout.
