What happens to your muscle determines What happens to your health.
Most people find out to late.Â
I'm here to change that.
I'm Donna McCook — Physiotherapist, Exercise Physiologist with thirty years in clinical practice experience behind me in health and injury rehabilitation including with applied back pain rehab, exercise prescription for bone health (osteoporosis / osteopenia) and muscle health (with aging, post cancer and post illness), and managing the physical changes associated with menopause.
I am currently a PhD Candidate researching how the significant weight loss, now readily possible with GLP-1RA medications, impacts muscle health. I'm researching this because I am concerned.Â
Losing muscle during weight loss may feel like an acceptable trade-off for you today; but we may well be trading today's health problems for a far bigger one down the track if we are just passive in the process.Â
For women especially, I query how much muscle loss is really ok. Particularly as we age. I'm not comfortable waiting for that conversation to catch up. So - I am bringing together what I have learnt so far to share with you so you too can make informed decisions about on ways to invest in your future self.Â

Redefine. Recompose. Rebuild.
Three pillars. One philosophy. Whether the conversation is about weight loss medications, menopause, or health and injury recovery — the clinical thread is the same. Muscle is not a fitness outcome. It is a metabolic organ, a structural foundation, and one of the most underestimated determinants of how well you age. Understanding it changes everything about how you approach your health.
Redefine
Muscle isn't just what moves you. It's what keeps you well. Understanding that is where everything changes.
Recompose
Improve your body composition as a health strategy - not an aesthetic goal. Learn how to protect your muscle at every stage of life.
Rebuild
Whether through weight loss, injury, pain or simply time - sometimes we need to recover what's lost. Come back stronger. Rebuild your strength.Â
