What this site is

SwimFast publishes general information about swimming technique and training. It is not coaching, not personalised training advice and not medical advice. Using it does not create a coach–athlete or professional relationship of any kind.

Safety

Swimming carries a real risk of drowning, and some training practices carry specific additional risks. Two in particular:

• Never swim alone. Use a supervised pool or open water with a companion and appropriate visibility equipment.
• Never practise breath-holding or hypoxic sets without direct supervision. Shallow-water blackout gives no warning and has killed strong, experienced swimmers. Nothing on this site should be read as encouragement to extend breath-holding.

Consult a doctor before beginning a new training programme, particularly if you have a cardiovascular condition, a respiratory condition, or a shoulder injury.

Accuracy

We take sourcing seriously — the editorial policy sets out how — but information here is provided as is, without warranty. Records, standards and published guidance change, and a page may be out of date between reviews. Where a decision matters, check the linked primary source.

Calculator results are estimates produced by published formulas with known limitations, which each calculator page states. They are not measurements.

Liability

To the fullest extent permitted by law, SwimFast and its author accept no liability for loss or injury arising from use of, or reliance on, anything published here. You train at your own risk and are responsible for your own safety in and around water.
