How to determine your muscle age and how to age-proof your muscles

We often think that losing muscle only happens to us when we reach retirement age. It actually starts happening in your late 30s and you can start losing about 8% of muscle mass every ten years from then. Due to other preoccupations in your life that affect diet and exercise, your muscles may be aging faster than your biological age. Here we explore how to determine your ‘muscle age’ and how to age proof them.1

What is muscle age?

The age of your muscles is an indication of your strength and performance of the muscles in the lower limbs versus your actual biological age. Simply put, it is how old you feel compared to how old you really are. You can actually determine your muscle age by simply performing a sit to stand test.1, 2
