Biomechanical evidence, resistance adaptation, progressive overload, and movement efficiency.
Low-intensity aerobic work does not destroy muscle tissue or blunt hypertrophy. When applied correctly, it expands left ventricular stroke volume, multiplies capillary networks, and accelerates recovery between resistance training sets.
Lifelong strength does not require abandoning heavy compound lifts after 40. It requires understanding changes in tendon collagen cross-linking, joint lubrication, and managing intra-session volume to sustain high output for decades.
One hour in the gym cannot counteract 10 hours of stationary seated posture. Understanding non-exercise activity thermogenesis and the molecular kinetics of lipoprotein lipase changes how we view daily movement.
