General, unofficial information

gymnical is an independent site. It is not affiliated with, endorsed by, or connected to any government agency or to any organization named on the site. Figures, dates and other data are unofficial copies or estimates for general information only. Nothing on the site is financial, tax, legal, medical or safety advice. Results are estimates from published formulas and public data for healthy adults. They are not medical advice, not a diagnosis and not a training prescription. Talk to a doctor before starting a new exercise program or a maximal test if you have a health condition, an injury or any doubt, and stop if you feel pain, dizziness or chest discomfort.
