Generic over-60 plans
Standard fitness programs assume you just need light movement. They do not program sternal precautions or account for fluid-aware routines when you have stable heart failure.
For cardiac rehab graduates: Keep your heart routine going after Phase II rehab.
Finding the right exercise after cardiac rehab means knowing your limits. This AI coach programs RPE-anchored aerobic work and breath-led strength alongside your clinician's clearance, checking your resting pulse before every session.

The problem
Why standard fitness plans miss the mark
02
Heart-rate obsession
Most apps push you to hit a target heart rate. That metric often breaks when you take certain prescriptions, leaving you guessing your actual effort.
03
Skipping the daily check
Generic routines just tell you to push play. They do not ask for your resting pulse, blood pressure, or symptoms before you start a session.
The method
How HeartStrong Fitness programs your week
01
Pre-session gate
You do not just start a workout. The coach asks for your vitals first.
RuleChecks your resting pulse and blood pressure before every single session.
02
Talk-test pacing
Heart rate monitors can mislead you. The coach relies on perceived exertion.
RuleAnchors your aerobic effort to the talk test, not heart rate.
03
Breath-led strength
Lifting requires specific breathing techniques to manage physical stress.
RulePrograms sternal-precaution scaling and cues you to exhale on every effort.
04
Fluid-aware nutrition
Meals are low-sodium Mediterranean, the coach scales a protein target to your bodyweight, and a Fluid-Watch Day menu is ready for mornings the scale jumps.
RuleFour low-sodium Mediterranean meals a day, seasoned with herbs, not salt

Built to adapt
A plan that moves when your week does.
It reads your recovery
Connect Apple Health or Health Connect. When sleep, HRV or resting heart rate say you are under-recovered, today's session gets lighter. Planned deloads follow your coach's schedule, and you can ask for one in chat.
Chat that changes the plan
Travelling, sore, short on time, missed a meal: tell your coach at any hour. It rebuilds the week or re-portions the day, and confirms the change in chat.
Check-ins it acts on
Daily check-ins and progress photos go to your coach, and your plan is adjusted from what actually happened, not what was scheduled.

How this coach works
What HeartStrong Fitness does, and what it leaves to your clinician.
- Your plan comes from HeartStrong Fitness's written programme — the week, how load goes up, when it backs off and how it feeds you, as shown above — matched to your intake: goals, schedule, equipment, injuries and the health details you share.
- It is an AI fitness coach, not a clinician. It does not diagnose, treat or change medication, and it works inside the limits your clinician sets.
- When your wearable shows low recovery, today's session gets lighter. Planned deloads follow the programme's schedule, and you can ask for one in chat at any time.
- The programme was written for this coach and is checked by automated rules. No clinician has reviewed it, and none of the organisations below has reviewed or endorsed Agents4 Fitness.
Train within the limits your cardiologist or cardiac rehab team set. Chest pain, unusual breathlessness, dizziness or palpitations mean stop and get urgent medical help.

Questions
Straight answers.
Something else? Ask your coach in chat once you are in. It answers at any hour.
How does this fit with my doctor's advice?
This coach works alongside your care team. You need clearance for unsupervised exercise first; the menus are low-sodium, and any sodium or fluid limit your team sets comes first.
What if I take medication that lowers my heart rate?
The coach anchors your aerobic work to effort and the talk test, rather than relying on a heart-rate monitor that your prescriptions might mask.
How do you handle sternal precautions?
The coach scales every strength exercise to respect sternal precautions. It also runs a pre-session gate to check your resting pulse and symptoms before you start.
Do I need a full gym?
No. You need a flat walking route or a bike, a resistance band, a chair, a wall and a single stair, and sessions run up to 45 minutes.
What happens on days I feel too fatigued?
The app reads your Apple Health or Health Connect data. If your recovery is low, the coach makes today's session lighter, or you can ask for a deload in the chat.
What do I get for free?
Your account is free — browse coaches, explore the app, and connect with a coach. Each AI coach is a monthly subscription (priced by coach); cancel anytime in a tap.
Is this a real coach or an AI?
It's an AI coach built on a real training methodology for this exact niche. It writes your plans, adjusts them from your check-ins and progress, and answers questions any time — no waiting for office hours.
What if it doesn't fit my situation?
Your plan is built from YOUR intake — goals, schedule, equipment, injuries, preferences. If something doesn't fit, tell your coach in chat and it adjusts. And you can cancel any subscription anytime.
What happens to my data?
Your data stays yours. We never sell it, and you can export or delete your account at any time. See our Privacy Policy for the details.
