Adaptive Training Plans: How the Plan Adjusts to You
Adaptive training is real science with honest limitations. What peer-reviewed research says about autoregulation and HRV-guided plans, and how Movement Rebels applies it. 7-day free trial.
Heat Acclimation When You Train in a Cold Climate
Preparing for a hot race when you live somewhere cold. Sauna protocols, hot baths, overdressing, and the plasma-volume adaptation explained honestly, with the studies to back it up.
How to Taper: Arrive Fresh Without Losing Fitness
Cut volume 40-60%, keep intensity, and you peak. The evidence is clear. Most athletes get it wrong by resting too much, not too little. Here is the honest science and a practical execution guide.
Normalized Power Explained: The Algorithm Is Sound, the Hype Around It Is Not
Normalized Power weights variable efforts to estimate real physiological cost. The math is solid. The blind spot the hype skips: NP is only as good as your FTP, and FTP is a moving target.
Periodization for Recreational Athletes: Which Model, and How Much You Need
Linear, block, undulating: the honest evidence on which periodization model recreational athletes actually need, and what the research says about adherence, minimum dose, and adapting on the fly.
Training Stress Score (TSS): Useful Number, Wrong Anchor
TSS quantifies session load well. The mistake is treating it as a recovery metric. Here's what it measures, where it breaks, and how to actually use it alongside the signals it ignores.
VO2 Max Intervals: The Sessions That Raise Your Ceiling
3-5 minute reps near 90-95% HRmax with near-full recovery are what the evidence actually supports for raising VO2max. Dose, work:rest, weekly frequency, and why most people run them wrong.
Zone 2 Heart Rate: Find Your Real Z2
Your watch zone is probably wrong. 220-age misses individual max HR by 10-15 bpm. Here's how to find your actual LT1 ceiling with the talk test, drift method, ramp protocol, or a lab.
Zone 2 Training: When It Works, When It's a Waste
Zone 2 is real, old, and oversold. Here's the honest version: when low-intensity volume is your highest-leverage work, when it isn't, and how to execute it without wasting easy days on junk tempo.
