01
High reps, low weight
Generic light circuits do not provide the heavy-enough load your hips and spine require to respond.
For low T-scores: Heavy bone loading with a neutral spine.
When your doctor clears you for an osteoporosis exercise program, this AI coach programs the heavy hip loading and neutral-spine lifting you need. It includes a gated impact ladder and daily balance work.

Axial Bone Loading
3–45 min · from your plan
You: My lower back started hurting yesterday. Should I still do today's squats?
Your coach: Not today. With new back pain, your pre-session check stops the session and nothing gets loaded. See your doctor first, then tell me what they found.

The problem
Why standard workouts fail this audience
02
Crunches and loaded flexion
Most fitness plans program sit-ups, which bend the spine under load and increase the risk of vertebral fractures.
03
Balance takes a back seat
Standard plans focus only on lifting, ignoring the reactive balance and fall-proofing skills you need daily.
The method
How your coach builds the plan
01
Neutral-spine lifting
Bone responds to heavy loads, but bending under that load is how vertebrae fracture. You will only lift with a neutral spine.
RuleThe coach programs heavy lifting while keeping your spine strictly neutral.
02
Gated impact ladder
Impact is introduced gradually. The post-fracture path skips impact entirely until your clinician clears you to progress.
RuleOne rung every two weeks, only with your doctor's clearance.
03
Daily balance work
Strength alone is not enough. Every day has a balance minute, and Tuesday and Saturday add fall-proofing skills such as floor recovery and reactive stepping.
RuleA balance minute every day; fall-proofing skills twice a week.
04
Calcium-forward nutrition
Your body can only absorb a certain amount of calcium at once. The plan spreads your intake, with vitamin D for absorption.
RuleCalcium is distributed across 4 meals to match what you absorb.

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 BoneStrong Fitness does, and what it leaves to your clinician.
- Your plan comes from BoneStrong 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.
Your clinician manages your condition and any medication; your coach plans training and food inside the limits they set.

Questions
Straight answers.
Something else? Ask your coach in chat once you are in. It answers at any hour.
What equipment do I need?
The plan uses dumbbells, a kettlebell or hex bar, a bench, a step, a chair and a resistance band, with a counter or rail for support. Missing one? Ask your coach to swap that exercise.
Does this work if I am recovering from a fracture?
Yes. The coach programs a specific post-fracture path that skips all impact until your clinician clears you to progress.
Can the nutrition plan accommodate a dairy-free diet?
Yes. Your coach has a Dairy-Free Calcium Day that spreads calcium across 4 meals with fortified soy milk, calcium-set tofu, sardines and greens; switch any date to it in the app.
Does the program include core work like crunches?
No. Loaded flexion is how vertebrae fracture. Your coach programs core stability work that keeps your spine strictly neutral.
How does the coach handle days when I feel exhausted?
The coach reads your sleep and resting heart rate from Apple Health or Health Connect. It makes today's session lighter when your recovery is low.
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.
