Section 1 — My Heart Rate Zone Calculator

Fill in your age and calculate your personal heart rate zones.

My age:     Estimated MHR (220 − age):   bpm

Zone% MHRMy Range (bpm)How It FeelsPrimary Use
Zone 150–60%
Very easy, can singWarm-up, cool-down, rest days
Zone 260–70%
Easy, full conversationAerobic base, fat burning
Zone 370–80%
Moderate, short sentencesAerobic capacity, tempo
Zone 480–90%
Hard, barely speakingLactate threshold, intervals
Zone 590–100%
Maximum, cannot speakVO2 Max, sprint intervals

Formula: Zone bpm = MHR × Zone%    e.g. Zone 2 lower = MHR × 0.60    Zone 2 upper = MHR × 0.70

Section 2 — 8-Week Progressive Cardio Plan

Complete the session log after each cardio session. Target zones are guidelines — listen to your body.

Weeks 1–2: Foundation (Zone 2 Only)

SessionDateEquipment UsedDurationAvg HR / ZoneNotes / Effort
W1 Cardio 120 mins Zone 2
W1 Cardio 220 mins Zone 2
W2 Cardio 122 mins Zone 2
W2 Cardio 222 mins Zone 2

Weeks 3–4: Building (Zone 2 + Zone 3 Introduction)

SessionDateEquipmentDuration / TargetAvg HRNotes
W3 Cardio 125 mins Zone 2
W3 Cardio 225 mins Zone 2–3
W4 Cardio 128 mins Zone 2
W4 Cardio 228 mins Zone 2–3

Weeks 5–6: Developing (Zone 2 + First HIIT Session)

SessionDateEquipmentDuration / TargetAvg HRNotes
W5 LISS30 mins Zone 2
W5 HIIT8×(30s hard / 90s easy)
W6 LISS32 mins Zone 2
W6 HIIT10×(30s hard / 90s easy)

Weeks 7–8: Consolidating (Zone 2 + Longer HIIT)

SessionDateEquipmentDuration / TargetAvg HRNotes
W7 LISS35 mins Zone 2
W7 HIIT12×(30s hard / 60s easy)
W8 LISS35 mins Zone 2–3
W8 HIIT2×(5 mins Zone 4 / 3 mins easy)

Section 3 — LISS vs HIIT Comparison

LISSHIIT
Intensity60–70% MHR, Zone 285–95% MHR, Zone 4–5
Duration30–90 minutes15–30 minutes total
Primary energy systemOxidative (aerobic)Glycolytic + Oxidative
Best forAerobic base, fat oxidation, recoveryVO2 Max, lactate threshold, time efficiency
Recovery neededLow — can do most daysHigh — max 2–3x per week
Beginner recommendationStart here for 4–6 weeksIntroduce after aerobic base is built
EPOC (afterburn)MinimalSignificant — elevated calorie burn for hours after

Section 4 — Equipment Technique Notes

Make notes on what you have practised and what to focus on next time:
