I was working out earlier and found something intresting about my body. I was able to divert strength from my legs into arms and make my muscles stronger. I could feel it in my arms. My muscles grew tenser for the impact. This is muscle memory right? And if it is then could the mind literally tell the body to do amazing things? Like divert energy to jump 10 feet in the air? Don't get me wrong it wiped me out. I am very very tired now. I just want peoples opinions on the subject. Just be nice please. No need to call me any names. I know this is out there.
