Out on the trail, keeping this pace conversational — that's Zone 2.
Run or cycle steady for 45 min targeting Zone 2 by heart rate. Once per month finger-prick a lactate meter at the end of the session — staying ≤ 2.0 mmol/L confirms you are truly in Zone 2. Without testing most people drift into Zone 3.
The protocol
| Target | ≤ 2.0 mmol/L |
| Duration | 45 min |
| Frequency | 3–5x/week |
| Lactate check | monthly, end of session |
Skip this if
- anaemia
- uncontrolled cardiovascular disease
- finger-stick aversion
Zones off an age formula are a guess — the meter I prick a finger on is where mine came from.
Full transcript
Out on the trail, keeping this pace conversational — that's Zone 2. Easy enough to talk in full sentences, hard enough that you're still moving. Thirty minutes here, three times a week, and you're building the mitochondrial base that makes everything else — sprints, recovery, focus — work better. More protocols like this on agegen.ai.
