Answer: Vertebrae
Explanation: Your back is composed of twenty-four individual bones called vertebrae that are stacked one on top of the other to make up your backbone or spinal column. The entire column sits on the sacrum, a large triangular bone that connects the spine to the hips. The top seven vertebrae in the neck are called the cervical spine.
Physical activity should be a balance. It is important to have a mix of moderate, low, and vigorous activity! From walking to yoga to crossfit it is important to keep a balance.
