On the exercise cards there is an arrow button on the right side. click on this to browse progressions. The progressions are listed in order of difficulty. Inside the progressions selection, you can click on the picture of the progression to reveal the video and form cue description.

YES, of course - if you are able to stick to the specified rep range for the exercise, then go ahead. Especially for technical exercises, some steps may be ambiguous for some people. Other times, two progressions may even be of the same difficulty, just in a different way, or with different equipment so you can choose what is most convenient for you. We are also all different, so in a few cases, one progression that is considered more difficult for some, may be easier for you and vice versa.

In some cases however, you may even want to introduce your own progressions between two progressions by doing what I like to call progression interpolation.

In short this means that for progressions including distances and depths, you can create an intermediate progression with the distance, or depth in between the one specified by the two separate progressions.

The difference between a module and a workout is that a module is not regarded as a complete general workout, but a complete specific workout for a specific skill. It includes specific warm-up only, so if you are only doing a module stand alone (not after, or in another workout), a general warm-up is recommended before starting.

In other words, a workout has a wider purpose and is complete in the sense that it also includes a more gerneral warm-up. Many workouts are however also "specialized", but the category of specialisation is somewhat wider than for modules.

As an example, "Planche 1 module", only contains specific warm-up targeting muscles relevant for planche training. The module itself, only uses drills relevant to improve planche strength and to learn the planhce (or tuck planche in the case of planche 1 module). The "straight arm L2" which is a workout on the other hand contains a complete wam-up and exercises and drills for both planche and front lever as well as core strength

The terms "modules" and "workouts" and the difference explained here is not a general thing, but a differentiation I have made in order to provide flexible solutions oin terms of programming.
