Health & safety disclaimer

BLACKBONE helps you plan, log and track strength training. Please read this page before you use it. It is part of our terms of service.

1. Not medical advice

Everything in BLACKBONE is general information: the exercise library and its videos, generated workouts, programs, calculators, strength levels, recovery estimates and guides. None of it is medical, physiotherapy or nutrition advice, and none of it is made for your body or your health history. It does not replace a doctor, physiotherapist, dietitian or qualified coach who has assessed you in person.

2. Check with a professional first

Talk to a doctor before you start or change a training program, especially if you:

• have a heart, lung, blood pressure, joint or other health condition;
• have an injury, recent surgery, or pain that hasn't been checked;
• are pregnant or have recently given birth;
• take medication that affects your heart rate, balance or blood pressure;
• haven't trained in a long time, or are new to lifting weights.

3. Train within your limits

• Warm up, learn the movement with light weights, and add load gradually.
• Use a spotter, safety bars or collars for heavy lifts, and keep the area clear.
• Choose weights you can control for every rep. The numbers the app suggests are a starting point, not a target you must reach.
• Rest and recover between hard sessions, eat and drink enough, and sleep.

4. Stop if something feels wrong

Stop training straight away if you feel chest pain or pressure, severe shortness of breath, dizziness or faintness, sharp or sudden pain, or anything that worries you. Get medical help if it doesn't pass quickly. In an emergency, call your local emergency number.

5. What the app's numbers mean

• Estimates. One-rep max, strength levels, body fat, calories, recovery and similar figures are calculated from formulas and averages. They can be wrong for you.
• Limitations. Choosing areas to work around hides some exercises, but the app can't judge your particular injury or tell you an exercise is safe for it.
• Exercise videos show one way to do a movement. Your setup, range of motion and equipment may need to differ.

6. Coaches

Coaches listed in BLACKBONE have shown us a certification, which we checked before approving them. We don't supervise their advice. A coach is responsible for the guidance they give, and you decide what to follow and what to share with them.

7. Your responsibility

Exercise always carries some risk of injury. You decide what you lift and how, and you train at your own risk, to the extent the law allows. Our terms of service explain the limits of our responsibility.
