Iterative Refinement
Iterative refinement refers to Phase 2 (approximately 2009–2020) of Baseworks development, during which the method was continuously modified in interaction with 10,000+ learners over ~10 years, with the goal of maximizing Communicability.
The Feedback Loop
Section titled “The Feedback Loop”- Teach a movement to diverse learners (including LBA learners)
- Observe where communication breaks down (learners misinterpret, cannot execute, or default to habitual patterns)
- Modify both the movement itself and/or how it is instructed to reduce that specific breakdown
- Teach again; repeat
Prerequisite Constraint
Section titled “Prerequisite Constraint”Safety was a prerequisite constraint throughout — movements had to be “fool-proof” in the sense that even misexecution should not cause injury. However, safety is not a unique constraint (most responsible movement practices optimize for safety). What makes Baseworks unique is that, with safety as a given, the additional optimization criterion was communicability — not performance, not tradition, not therapeutic outcome.
What Was Modified
Section titled “What Was Modified”Both the movements themselves and the instructional approach were modified, though the line between the two is blurry:
- Forms were simplified and organized into step-by-step progressions (which eventually formalized into FSA)
- Symmetry and spatial constraints were imposed, changing the appearance of forms (which eventually formalized into GS)
- Identified bottlenecks were targeted: when students consistently struggled with a particular aspect, that aspect was given more training time — even if this meant more students would fail within a single session — because the bottleneck needed to be addressed for long-term communicability
- Instructional redundancies were introduced: cues like “draw the shoulders down” were applied across all movements as a default, even in contexts where the biomechanical benefit was unclear, because consistency made the system easier to teach and learn
- Foci emerged: as elements like GRAVITY, TRANSPOSE, and EQUATE began appearing across forms with different movement dynamics, the understanding of what was being trained in each form shifted from a macro-movement goal to a perceptual/control goal
The Macro/Micro Distinction
Section titled “The Macro/Micro Distinction”The movement pattern / macro-movement distinction emerged gradually. Early instructor feedback was intuitive (“there’s too much silence — you need to keep talking” or “the whole body needs to be active”). Over time, these intuitive corrections were pushed toward distinct, nameable principles.
Naming History
Section titled “Naming History”By the time Reverse Engineering began (~2016), several terms were already in active instructional use: “distributed activation,” “micro-movements” (originally referring to spine/ribcage), “natural breathing,” and “intensity modification.” Other principles existed as specific cues but had not yet been unified into named principles.
