Where does punching power come from?
I heard that it comes from the shoulders, and partially the legs, but others say its from practice and gradually getting stronger at throwing punches.
Whenever i get in (street) fights, i notice that i have muscle soreness in parts of my back. Is this from using muscle that hardly get used or just from moving strangely?
Are there any excersizes to improve punching power?
Any answers would be great!
