VO2 Max Training Strategy
| Phase | Method | Mechanism | RPE Target |
|---|---|---|---|
| Wks 1–3 | Zone 2 base + movement habits | Builds mitochondrial density, fat oxidation, cardiac stroke volume | 3–4 |
| Wks 4–6 | Extended Zone 2 + tempo pickups | Longer aerobic bouts deepen mitochondrial adaptation; pickups prime interval tolerance | 4–5 |
| Wks 7–9 | Zone 2 + true VO2 Max intervals (1–2 min hard) | Short hard bouts maximally stress the oxygen delivery system; base sustains recovery | 4 base / 6–7 intervals |
| Wks 10–11 | Peak intervals + taper | Final stimulus followed by recovery — supercompensation window for VO2 Max gains | 3–7 then 3–4 |
Note: Because BP medication may blunt heart rate response, always use RPE as your primary intensity guide. Zone 2 = you can speak full sentences comfortably. Intervals = clearly hard but not desperate.
HRV & Recovery Habits
Sleep First
7–9 hours nightly with a consistent wake time is the single largest driver of HRV improvement. One night of poor sleep can suppress HRV for 24–48 hours.
BP Medication & HR Zones
Beta-blockers and some other antihypertensives blunt peak HR. Never chase a heart rate number — use RPE exclusively. Your perceived effort is the accurate signal.
Stress Management
Even 5–10 min of slow diaphragmatic breathing (4-sec inhale, 6-sec exhale) daily produces measurable HRV improvement within 2–4 weeks. Do it before sleep.
Alcohol
Even 1–2 drinks suppresses HRV for 24–48 hours after. If HRV tracking is a goal, limiting alcohol during the 12 weeks will produce the most visible results.
Tracking HRV
Measure first thing in the morning before getting up. Apps: HRV4Training (phone camera), Elite HRV, or a Garmin/Polar wearable. Use a 7-day rolling average — not single readings.
When to Back Off
If HRV drops more than 10% below your baseline for 2+ consecutive days, reduce that week's intensity — swap a cardio session for an easy walk or yoga. The plan serves you, not the reverse.
