- Why resting heart rate, sleep hours, step count, and VO2 Max are the right four metrics to track
The Opportunity
Your iPhone has been tracking health metrics since the first day you carried it. Step count, resting heart rate, sleep hours, VO2 Max if you have an Apple Watch. The data exists. Most people never look at it beyond the weekly summary notification.
A 10-minute weekly check-in with ChatGPT turns that passive data collection into an active health monitoring brief. Not a diagnosis. Not medical advice. A structured read on the metrics your body produces every day.
This is a PromptHacker Premium article.

The Four Metrics That Matter
The Apple Health export contains hundreds of data points. Four produce the highest signal for executive health monitoring without requiring clinical expertise to interpret:
1. Resting Heart Rate (RHR). The average heart rate while at rest - available from iPhone with wrist detection or, more accurately, from Apple Watch. A sustained increase of 5+ BPM from your personal baseline without an explanatory cause (illness, altitude, alcohol) is a reliable early indicator of physiological stress, poor recovery, or overtraining. Track the 7-day rolling average, not the daily reading.
2. Sleep Hours (and Sleep Score with Apple Watch). Total sleep time from iPhone is available without Apple Watch, but Apple Watch adds sleep stages and sleep score. The actionable threshold: below 6.5 hours average for more than 3 consecutive days produces measurable cognitive performance degradation. This is the threshold where the brief should flag the pattern.
3. Step Count Weekly Total. Step count as a proxy for overall movement. The 7,000 to 8,000 steps per day range is the threshold associated with all-cause mortality reduction in peer-reviewed literature (JAMA Neurology, 2022; JAMA Internal Medicine, 2023). Track weekly total, not daily.
4. VO2 Max trend (Apple Watch required). VO2 Max is a direct measure of cardiovascular fitness. Apple Watch estimates it from outdoor walking and running workouts. A declining VO2 Max trend over 8 to 12 weeks is the most lagging but most meaningful signal in the standard Apple Health data set.
Getting Your Numbers
From iPhone:
- Open the Health app
- Tap the Summary tab
- Browse the Browse tab for each metric individually, or read the weekly averages on the Summary tab
For the quickest workflow: open the Health app, browse the Summary tab, note the 7-day averages for each of the four metrics above. Takes 90 seconds.
For Apple Watch wearers: the Vitals app (watchOS 11+) shows the same four metrics on a single screen.
The Weekly Check-In Prompt
I am going to share my iPhone health metrics from the past 7 days. Based only on these numbers, give me a structured health brief with three sections: 1. PATTERNS TO NOTE - any metrics outside typical healthy ranges or showing a direction change from the prior week if I provide those 2. ONE THING TO PRIORITIZE this week based on what the data shows 3. ONE QUESTION TO ASK MY PHYSICIAN at my next appointment if any metric warrants professional follow-up My metrics this week: Resting Heart Rate (7-day avg): [X] BPM Sleep (7-day avg): [X] hours Steps (weekly total): [X] VO2 Max (most recent Apple Watch estimate): [X] - skip if unavailable Prior week for comparison (optional): Resting Heart Rate: [X] BPM Sleep: [X] hours Steps: [X] VO2 Max: [X] Do not make diagnostic claims. Flag patterns worth attention and note when a pattern crosses a threshold that warrants a physician conversation.
The Monthly Trend Prompt
Run this at the end of each month. Paste four weeks of numbers.
Here are my iPhone health metrics for the past 4 weeks. Identify any trends moving in a concerning direction over the full month, and any metrics that are improving. Summarize the month in 3 to 5 sentences and flag the one metric most worth discussing with my physician. Week 1: RHR [X] BPM, Sleep [X]h, Steps [X], VO2 Max [X] Week 2: RHR [X] BPM, Sleep [X]h, Steps [X], VO2 Max [X] Week 3: RHR [X] BPM, Sleep [X]h, Steps [X], VO2 Max [X] Week 4: RHR [X] BPM, Sleep [X]h, Steps [X], VO2 Max [X]
Using the Brief With Your Physician
The weekly brief is designed to produce one specific output: a question worth asking your physician. Not a list of concerns - one question, when the data warrants it.
The physician interaction is most productive when you arrive with a specific pattern ("my resting heart rate has been 7 BPM above my normal baseline for 3 weeks") rather than a general worry. Print the monthly trend summary and bring it to your annual physical. A physician who sees a 4-week RHR trend, sleep pattern, and VO2 Max trajectory can act on that data in 5 minutes. The same conversation without the data takes 15 minutes and produces less actionable output.

Action Steps
- Open your Health app this week and check the Summary tab for the four metrics above. Note the 7-day averages and write them down or save them to a Note.
- Run the weekly check-in prompt with this week's numbers. If you have last week's numbers, include them for comparison.
- Save the output. A simple Note on your iPhone with the weekly brief and the date creates the running health record that powers the monthly trend prompt.
- Set a weekly calendar reminder for Sunday evening or Monday morning: "Health check-in - 10 minutes." The prompt takes 5 minutes to run once you have the metrics noted.
- Run the monthly trend prompt at the end of each month and bring the output to any scheduled physician appointments. This is the step that converts the weekly brief from useful to clinically actionable.
