The Flag · Long-Length Isometrics For Tendons · 2026-07-26 This week's Deep Read: whether end-range isometric holds build the tendon stiffness straight-arm lever work demands. Opening Flag A 2025 Experimental Physiology review (McMahon et al.) synthesizes evidence that isometric training at longer muscle-tendon lengths beats shorter lengths for tendon mechanical
The weekly architecture behind steady skill progress: ordering rules, the three dials, pairing skills, and the 4-week review.
Two different adaptations, two different training methods — and the diagnostic that tells you which one is stalling your skill.
The mechanics behind every progression ladder: joint torque, moment arms, straight-arm vs bent-arm adaptation, and how to read any ladder like a coach.
