No gym needed? Scientists in China develop self-exercising muscle grafts

Scientists in China have developed a novel self-exercising muscle graft. This innovation involves injecting muscle cells below the skin, which then self-assemble into functional muscle grafts. In studies conducted on mice, these "myografts" demonstrated the ability to improve whole-body muscle mass. Furthermore, they led to positive effects on bone density, endurance, liver function, and cognitive health. The researchers believe these myografts could offer the health benefits of exercise to individuals with age-related conditions like Alzheimer's and osteoporosis, and potentially to those seeking muscle gain without physical exertion.
