For almost a year, Scott Kelly did not have to use his legs to walk, but instead floated to different areas of the space station. In the past, astronauts would leave space with brittle bones and weak muscles because of the lack of use while in space, according to Scott.
But today, researchers have helped mitigate the impact on bones and muscles by implementing extensive workout routines that astronauts carry out while in space. Scott said onboard the International Space Station astronauts tie themselves down to a treadmill, strap into a bike and use a resistance device to work out for 2 to 2.5 hours a day.
“The workouts have positively impacted the astronauts' bones and muscles, and they are coming back in really good shape,” he said. “But some are losing bone and muscle but not as much as we saw in the early days."
When the bones breakdown, they release calcium, which can also lead to kidney stone formation and bone fractures. Likewise, the lack of use causes muscles to become weak and shrink, which can leave astronauts less coordinated when they return to Earth

One obvious and temporary change for Kelly was that he came back 2 inches taller than his brother because a lack of gravity causes spinal disks to expand.
[When astronauts return to Earth, they must re-adjust to gravity and can have issues with balance and simple tasks like standing up, walking or operating a vehicle.
Scott said astronauts go through a physical reconditioning program and are typically functioning normally within one-to-three weeks unless they've suffered significant bone or muscle loss, which could take months or years to recover from

@Mowgli you should go to space and come back like goku
Won't Earth gravity just shrink them back down?
