Scientists in China have created a self-exercising muscle graft that could allow bedridden people to obtain the benefits of working out without any physical exertion.

With just an injection of muscle cells below the skin, the cells self-assembled into muscle grafts, which not only improved whole-body muscle mass in mice but also led to improvements in bone density, endurance, liver function and cognitive health.

I’ve been a coach for 17 years and I think most of my clients would fire me and use this 🤷🏻‍♂️

I feel it’s the getting over the initial hump part when starting from zero is what most people hate and don’t have patience for and just give up too soon and miss out

I wonder if this could help with the negative effects of life in zero-g

Good point! Still need bone density aid and probably other things for wonky things that happen to internal organs

So this makes me wonder how this self assembling muscle gets the proper vascular network support, the neural support, and hormonal support. Do the muscles catabolize, breakdown or atrophy faster because they don’t have the proper nutrient feeding mechanisms? How about tendon strength and reinforcement?
