Create a progressive zone 2 cardio plan for building aerobic fitness with heart-rate guidance, talk-test cues, recovery checks, and schedule adaptations.
Prompt Template
Act as an endurance coach creating a safe, progressive Zone 2 cardio base-building plan. Design a [duration]-week plan for [person/profile] with [current fitness level] and [primary goal]. Available days per week: [days] Preferred modalities: [walking, cycling, running, rowing, swimming, elliptical] Session length available: [minutes] Heart-rate data available: [max HR, lactate threshold, resting HR, or none] Constraints/injuries: [constraints] Strength training or sport schedule: [other training] Recovery concerns: [sleep, stress, soreness] Include: 1. **Zone 2 target** — heart-rate estimate plus talk-test/RPE cues 2. **Weekly schedule** — sessions, modality, duration, and intensity 3. **Progression rules** — how volume increases and when to hold steady 4. **Warm-up and cool-down template** 5. **Recovery checks** — signs to reduce volume or intensity 6. **Optional strength/mobility support** 7. **Travel/bad-weather alternatives** 8. **Tracking dashboard** — metrics to log weekly Add a short safety note: this is general fitness guidance and anyone with medical concerns should check with a qualified professional.
Example Output
Zone 2 Target
Estimated range: 118-132 bpm based on a 185 bpm estimated max HR. If heart-rate data feels inconsistent, use the talk test: you should be able to speak in full sentences, but singing would be difficult. RPE: 3-4/10.
Week 1 Schedule
| Day | Session | Details |
|---|---|---|
| Tue | Bike Zone 2 | 30 min easy spin, nasal breathing if comfortable |
| Thu | Incline walk | 25 min at conversational pace |
| Sat | Longer aerobic | 40 min bike or brisk walk, no surges |
Progression Rule
Add 5-10 minutes total per week only if sleep, soreness, and motivation remain stable. Every fourth week, reduce volume by 20%.
Tracking
Log duration, average HR, perceived effort, energy after session, and next-day soreness.
Tips for Best Results
- 💡Provide actual heart-rate data if you have it; otherwise ask for talk-test based guidance.
- 💡Keep Zone 2 easy enough that you can repeat it consistently — boring is often the feature, not the bug.
- 💡Mention other training so the plan does not overload your week.
- 💡Ask for indoor and travel alternatives if your schedule changes often.
