Articles on readiness, neural demand and programming — written by a sports scientist, with the data behind every claim.
A typical heavy session costs 43 units of neural cost. Halving the sets brings it to 21.5. Training the same muscles on cheaper movements brings it to 17 — and keeps more stimulus than the heavy day had.
Both leg curls return 4.50 per unit of neural cost — nothing in 272 movements returns more. The Romanian deadlift returns 0.94 and the barbell deadlift 0.45. Why the least fashionable machine in the gym scores highest.
59 of 272 movements give back less stimulus than they charge in neural cost — and 58 of those are simply every movement priced at 8 or above. The full list, and the four that still belong in most programmes.
Handstand Walk returns 0.44 per unit of neural cost. Ring Muscle-Up returns 0.44. They are the only two of 272 movements below 0.45 — and neither number is a programming error.
Sort all 272 movements by stimulus-to-fatigue ratio and the median is 1.38. The band around it holds 81 movements — more than any other tier in the library, and the one least written about.
Adolescent athletes who averaged under eight hours of sleep a night carried 1.7 times the injury risk across a season. Why that number belongs next to the neural-cost ledger, not instead of it.
77 of 272 movements sit at the lowest neural cost there is. Sixteen build muscle efficiently. The other sixty-one — mobility, prehab, activation, breathing — are insurance for the expensive work.
A systematic review set subjective wellbeing checks against HRV, resting heart rate and biochemical markers to see which one actually tracked training response. The chest strap lost — consistently.
Out of 272 movements, only eighteen reach 9.0 stimulus per unit of fatigue — and sixteen of them have a neural demand of 2. The complete list, grouped by muscle, for the days your body isn't there.
272 movements analysed. The deadlift returns 0.45 for every unit of fatigue it charges. A leg curl returns 4.50. That is a ten-fold difference — and almost nobody builds a week around it.
