Exercise and physical activity is one of the best tools to boost health, improve life expectancy and reduce treatment side effects.

– There is a reason for the creation of the term “Exercise is Medicine” –


Improve overall health and reduce cancer risk factors


Help patients throughout treatment and reduce severity of side effects


Minimize chance of recurrence

Mitigate acute and chronic side effects

Increase life expectancy and enhance quality of life



A safe, customized and effective exercise program helps clients experience…


Depression, Anxiety, Pain, Injury, Fatigue, Disease Recurrence


Coping, Strength, Energy, Endurance, Mobility, Sleep Quality, Ease in Activities of Daily Living, Functional Movement, Range of Motion, Posture, Balance


Cancer patients, survivors and those with chronic health risks are less active than the general population

They all want and need help when it comes to exercise

But there is a severe lack of health & fitness professionals who have the expertise required to support cancer patients and older adults with chronic conditions

This is because working with chronic conditions, cancer patients & survivors requires a much more knowledgeable and customized approach

If you’ve ever considered working with the cancer and aging population, perhaps you’ve wondered:

  • What credentials do I need to work with special needs clients?

  • What are the liabilities?

  • What are the recommendations and guidelines for working with cancer survivors and those with chronic conditions?

  • How can I customize those guidelines to work for each client?

  • What are the risks I need to be aware of?

  • How do I conduct an effective assessment before we begin?

  • What do I need to know about each type of cancer or condition?

  • How will current treatments affect my recommendations?

  • What is appropriate at different stages of the cancer and chronic disease journey?

  • How can I help my clients build healthy habits & exercise behaviors that stick?

Don’t take unnecessary risks with cancer patients/survivors and clients with chronic conditions. Let us provide you with the most current and evidence-based education to create safe and effective action plans.  

You will get the tools, confidence and support of the global leader in cancer and aging exercise education
