Polarised vs Pyramidal Training: How Elites Distribute Intensity
Stephen Seiler's research transformed how we think about training intensity. Polarised, pyramidal, and threshold — the data on which distribution produces the fastest adaptations.

Hypoxic Tents and Normobaric Altitude: What the Evidence Says
Home altitude tents simulate hypoxia at sea level via reduced oxygen fraction. Here's what the HIF-1α, EPO science, and real-world protocols show — and where they fall short.

Inspiratory Muscle Training: The Respiratory Limiter Intervals Miss
Dempsey 2006 identified the metaboreflex: inspiratory muscle fatigue diverts blood from working legs. McConnell Romer 2004 shows IMT gives 15% performance gain. Here's the protocol.

Genetic Potential and Trainability: What the HERITAGE Study Found
The HERITAGE Family Study trained 481 subjects identically for 20 weeks. VO2max gains ranged from 0% to 100%. The reason is gene-environment interaction — and it changes how we think about genetic potential.

Altitude Masks and VO₂max: What They Actually Train Is Your Breathing
Elevation training masks do not lower blood oxygen saturation or simulate altitude. But they do train inspiratory muscles — and that IS a real ergogenic. Here's the science.
