Long COVID Reconditioning — 25 Minutes

A paced, low-impact reconditioning session using nasal breathing and controlled effort (RPE ~3–5).

Warm-Up

Gradually raise heart rate and prepare joints while keeping effort easy. Paced approach to ease into movement.

March in Place and Step Ups target Type I slow-twitch fibers and mitochondrial density without triggering post-exertional malaise. Sit to Stand and Glute Bridge reload the posterior chain through controlled, closed-chain movement — restoring neuromuscular recruitment patterns that autonomic dysfunction often disrupts.

Why Post-COVID Bodies Demand Pacing

Why Post-COVID Bodies Demand Pacing

Long COVID impairs cellular energy production at the mitochondrial level, meaning perceived effort spikes disproportionately to actual output. Nasal breathing acts as a built-in throttle, keeping heart rate within parasympathetic-friendly zones and preventing the symptom flare that follows anaerobic threshold crossings.

RPE as Your Periodization Tool

RPE as Your Periodization Tool

Bird Dog and Cat-Cow aren't just mobility work — they retrain proprioception and spinal stabilization that fatigue and deconditioning erode. Track your RPE session to session; when RPE 3 feels like RPE 1 across two consecutive sessions, that's your signal to cautiously add one rep or one set — never both simultaneously.
