Real feedback from 22,000+ students, book readers, and coaching clients across 150 countries.
Across books, courses, and one-on-one coaching, the same themes come up again and again: clarity of instruction, biomechanical depth that other resources lack, and a coaching style that genuinely transforms training. Students describe Taco as "incredibly thoughtful and thorough" — someone who doesn't just show you what to do, but helps you understand why.
The certification program's rigor is mentioned frequently. With 40% of students giving up and 30% not passing, those who earn the certification value it precisely because it wasn't easy. Course feedback highlights the quality of 1-on-1 form review — every submission is personally assessed, and students aren't permitted to move on until technique meets the standard.
Book reviewers praise the combination of detailed photography, clear writing, and practical programming. Several note that Taco "spices things up rather than crunching through standard platitudes" — bringing genuine personality and real-world experience to technical content.
