Protocol cards, scientific rules, visual guides and carousels — free from Dr. Dragutin's Ph.D. knowledge base. No fluff. No guessing. Just science.
Downloadable PDF resources built from the same knowledge base used in the Ph.D. Protocol courses. Free preview — full programming in the complete courses.
Lactate threshold training protocols — from Zone 2 base building to LT2 ceiling work. Includes the VT1/VT2 Biofeedback Rule and complete protocol table.
Six scientific rules that define VO2 Max performance — from the LT2 relationship to metabolic flexibility and personalized threshold training.
One chest & back training session for each of the 5 neurotypes — methods, loading, tempo, rest and key principles. Train your brain, not just your muscles.
Scientific slides built for Instagram — navigate, screenshot and share. Each slide downloads as a high-resolution PNG.
Dopamine, Acetylcholine, Adrenaline, Glutamate, GABA, Serotonin — what motivates each and the training principle that fits.
Open Carousel →All 5 neurotypes decoded — training method, volume, intensity, fat loss protocol, worst mistakes. @opusathletic editorial style.
Open Carousel →The Point of No Return — LT2 definition, physiology table, same VO2 max different performance, 4 training protocols.
