Medical concerns
Do not use information from this website to delay or replace advice from a doctor or another appropriately qualified healthcare professional.
Seek professional advice before beginning or materially changing an exercise programme if you have an injury, diagnosed condition, unexplained symptoms, are pregnant or postpartum, take medication, or have been advised to restrict exercise.
Stop exercising and seek appropriate help if you experience concerning symptoms. If you need urgent medical help in the UK but it is not a life-threatening emergency, use NHS 111. Call 999 for a life-threatening emergency, in line with NHS emergency guidance.
Nutrition and supplements
Nutrition information is general and may not be appropriate for your health, dietary requirements, allergies, medication, training load or goals.
Do not use an article to diagnose a nutrient deficiency or begin high-dose supplementation. Supplements – including iron, vitamin D, caffeine, creatine, nitrate products and electrolytes – can be unnecessary, unsuitable or harmful in some circumstances. Seek advice from a doctor, pharmacist or registered dietitian when individual assessment is needed.
Competitive athletes are responsible for checking current anti-doping rules and the testing status of supplements they choose to use.
Training information
All exercise carries risk. Examples, sessions and training ranges are educational illustrations rather than personalised instructions. Adaptations may be required for your experience, health, environment and current fitness.
You are responsible for deciding whether an activity is appropriate for you and for obtaining professional support when needed.
