Terms of use and health disclaimer
Last updated: 22 October 2026
Sergeant Fitness (the app and the website at sergeant.fitness) is provided by Alderstrom Limited ("we", "us"), a company registered in the United Kingdom. By creating an account or using Sergeant Fitness you agree to these terms. If you don't agree, please don't use it. Questions: support@alderstrom.com.
Health disclaimer
Sergeant Fitness gives general fitness information only. It is not medical advice, and it does not diagnose, treat, cure or prevent any illness or condition. Nothing in the app, including what Sarge says, the exercise instructions, goals, step and weight targets, replaces advice from your doctor or another qualified health professional.
- Check with your doctor before you start this or any new exercise programme, and before changing your diet or aiming to lose weight. This matters most if you are pregnant or have recently given birth, have had surgery or an injury, or have a heart, blood pressure, breathing, back, joint, bone or other medical condition, or take medication.
- Stop straight away if you feel pain, dizziness, faintness, chest pain or tightness, unusual shortness of breath or palpitations, and get medical help if it doesn't pass. A gentle burn or tremble in a working muscle is normal; sharp or lasting pain is not.
- Never push into pain. Work within your own limits, use a sturdy chair or wall for balance, and exercise on a clear, non-slip floor.
- Weight and step targets are general suggestions, not a plan made for you. Aim for gradual change: a safe pace for most people is 0.5–1 kg (1–2 lb) a week.
- Sarge's tone is for motivation and fun. Never let it push you to train when you are unwell, injured or unsure.
You take part in the exercises at your own risk and are responsible for deciding whether they are suitable for you.

Your data
How we keep and use your information is set out in the privacy policy.
The service
We work to keep Sergeant Fitness accurate and available, but we provide it "as is" and can't promise it will always be available, error-free, or give any particular result. We may change, add or remove features.
Our liability
Nothing in these terms limits our liability for death or personal injury caused by our negligence, for fraud, or for anything else that the law does not allow us to limit, and nothing affects your statutory rights as a consumer. Otherwise, we are not responsible for loss or damage that was not a foreseeable result of our breaking these terms or failing to use reasonable care and skill, or for injury or loss that results from ignoring the health disclaimer above.
Changes and law
If we change these terms we'll update this page and the date at the top; continuing to use Sergeant Fitness after a change means you accept it. These terms are governed by the law of England and Wales, and if you live elsewhere in the UK you can also bring proceedings in your local courts.
