When training QM postures, the work consists in taking all the possible postures with front, back or side toward the ground and in going from one posture to the next in the easiest and fastest way possible. This work can be done statically, or better as a progression, moving through the changes of postures.
For instance, one can start in QM squat, move into forward hold by moving the hands forward, then move the feet toward the hands, etc. Such progression can be done head or feet first, with various combinations of squatting and extended QM postures.
The straight holds are excellent flexibility exercises, and one must join smoothly the different movements between postures and avoid a mechanical or rigid execution. These exercises can be done during a march or a run: stopping with the feet together or apart, one can squat and get into various QM postures before standing up and continuing.
The groupings can be done first by walking the hands and feet in various combinations (Planche 29 and 30) from squats to straight holds and inversely. The work can be made more dynamic (and harder) by moving both hands or both feet together (Planche 31). Note that in many cases it is better to progress in two steps (it can be harder, for instance when moving the feet back from squat to front hold).
Further combinations can be built to move smoothly (but not necessarily in one jump or walk) from one hold to another (Planche 32 and 33). Finally, movements of the trunk are also important to help transition smoothly between postures, and can be trained separately lying down (Planche 34).
