Sisters of Steel is general strength and fitness education. The training, videos and materials are for information only. They are not personalised to you, and using them does not create a coaching, medical or professional relationship between you and Colleen O'Leary or Sisters of Steel.

We are not medical professionals and this is not medical advice. Before starting this or any exercise programme, speak to your doctor first, particularly if any of the following apply to you:

  • a heart condition, chest pain, or high blood pressure
  • a bone, joint or muscle problem that exercise could make worse
  • dizziness or problems with balance
  • you are pregnant or have recently given birth
  • you have been inactive for a long time, or are returning from injury or illness
  • you take medication for a heart or blood pressure condition
  • any other reason you think you should check before exercising

You take part at your own risk. Exercise carries a risk of injury. Work at your own level, focus on good form, and never push through pain.

Stop straight away and get medical help if you feel pain, dizziness, chest pain, shortness of breath, or feel unwell at any point during or after training.

If your health changes after you join, check with your doctor again before carrying on.

Nothing here removes any legal rights you have, or limits our responsibility for injury caused by our own negligence where the law does not allow that to be excluded.
