Via medium of soul. Soul can store neutral spiritual energy and turn it into kinetic energy with training.

cant the spiritual energy ignore physics?
human
To some degree, yes; but it's not exactly ignoring it. Just like how electromagnetic energy isn't very affected by gravity. They are connected but their properties makes them ignore some of the implications of each other. 

That said, you can't create something out of nothing. Even if you could use materializing magic or some bs like that, you would need to spend the energy needed to form atomic connections, atoms, their subatomic particles, waves of those particles etc. 

Magic can look 'metaphysical' but that's the same look we have against electricity/lightnings from wayback. There will be a time where these type of stuff can be explained, studied and engineered for our own use.

if spiritual energy could do that then could it change things in the body?and also how would you even get that spirtual energy?meditating?
human
Yeah, as long as you give enough energy. But every change in body takes time to actualize. 

There's an infinite amount of energy in universe. We regularly digest it through breath and chakras daily, but it isn't enough so we need to sleep. While sleeping regeneration speed is higher. Meditation also helps too.

Problem isn't regeneration but capacity. Base humans have a low capacity for energy. Moment you reach your %80 limit or something soul stop accumulating energy and just spends it on random things. You can increase your capacity through meditation and similar practices. Just like workout, it takes time and to reach the top you need to devote your life into it like athletes. Casual practice is good for the common man just like exercise.
