Skeletal muscles are the muscles found in your legs and arms and throughout the body. The skeletal system is different from the smooth muscle system in organs like your liver and the cardiac muscle in your heart because the skeletal muscles contract voluntarily.
Increased storage of glycogen and fat. Resistance training is where your muscles have to deal with the stress that is put upon them. Increased muscle strength is a result of long term exercise because when your muscles are overworked (overloaded) this puts more weight on the muscles. Over time your muscles will deal with this resistance (weight) by increasing in size and helping you deal with the weight (this increases muscle strength).
