Cardiac muscle an involuntary muscle found only in your heart. It pumps blood around the body.
Skeletal muscle a voluntary or involuntary muscle that is attached to your bones for movement. It also helps protect your inner organs.
Voluntary muscle action muscle action that is under your control

Resistance exercise a great way to strengthen skeletal muscles. People work against the weight of an object in this exercise.
Aerobic exercise a steady, moderately intense activity. This kind of exercise mostly strengthens the heart and increases endurance.
Strain an injury in which a muscle or tendon is overstretched or torn. It often happens because a muscle has not been warmed up or is worked too hard.
Tendinitis People who exercise too much can hurt their tendons. The body can’t repair an injured tendon before the next exercise session,so the tendon becomes inflamed.
