what are some concepts that were a game changing?

one thing that helped me a lot is focusing on both elbows, both knees and waist positioning while doing some moves, a lot of power comes from them and not the exterior part, like hand and feet, for example when I punch, I focus on the position of the elbow and try to get it close to the chest as if I am doing butterfly machine, this makes me use the chest muscle and give a lot of power to punches,elbows and hooks, another thing for foot is when I kick I try to position my knee first to where I am kicking then actually kicking, I noticed alex periera and jon jones fo that a lot, this moves makes you front thighs, which is a big and strong muscle, for the waist I combine it with letting my legs off, so the body weight is in the puch or kick more

another part I noticed is shoulder movement, if you possesionyour elbow to you shoulder level and just push with your shoulder, it could give an advantage in close situations, also in rowing and pulling using traps and back shoulders are incredible

what other tricks do you guys have or know?
