There are two types of muscles: Voluntary and involuntary. Voluntary muscles work when they get a signal from the brain to do work like pulling. Involuntary muscles work without the brain telling them what to do. When we exercise our voluntary muscles, they function more efficiently. When they function efficiently, it becomes easier for us to do our work. The first lesson of exercise and the muscular system is that the muscles will function with greater ease and efficiency when they are exercised regularly.

Muscular exercise

Nerves inside muscles relay messages to and from the brain. Blood vessels bring food to the muscles which do the work that the brain has ordered. When they are exercised, muscles convert a food substance called glucose into energy. As the exercise is completed, carbon dioxide is given off as a waste product and heat is produced.

Benefits of exercise

Exercise makes sure your muscles are working hard. The harder muscles are exercised, the more they can do. The muscles need the proper intake of food (protein, complex carbohydrates and fats) along with water to do the maximum amount of work. Each contraction of the muscle makes it a more efficient tool to use. Each contraction with resistance helps the muscle grow and increases its capacity to do work.
