It’s time to revisit one of the basics of biology: mitochondria. These organelles, which occur in almost all types of human cells, generate adenosine triphosphate (ATP), the energy that cells use (Newman 2017; Newman 2018).

Every time you take a step, your piriformis muscles help to keep your stride in good form.
The piriformis is a flat, pyramid-shaped muscle in the gluteal region (you have one on each side of the body). Located behind the gluteus maximus, the piriformis attaches to the base of the spine (the sacrum) on one end and to the top of the femur, the trochanter, on the other end (Kenhub 2019; Chang, Jeno & Varacallo 2019).
