- The early changes that happen when people try to gain strength is largely driven by the nervous system. It gets better at recruiting the muscles we already have. While it’s important to be challenged, this doesn’t have to be grueling.
- Muscles change slower than the nervous system. Our body is always recycling tissue to keep it healthy. If we provide stress to the tissues they will produce more protein than we recycle, leading to increased muscle size and strength.
- Satellite cells donate cells to existing muscle, which helps with repairing tissue, remodeling tissue, and increasing our capacity to be strong now and into the future
