The benefits of exercise are vast. Better health, posture, balance, strength, endurance, mental agility, and reduced risk of heart attacks and strokes, osteoporosis, diabetes, depression and disease are just some of the rewards of engaging in regular exercise.

The specific systems of the body that benefit from exercise are the muscular and skeletal systems, cardiovascular or circulatory system, nervous system, digestive system, endocrine (hormone) system and immune systems.

The muscles, bones and joints of the muscular and skeletal systems increase in strength, endurance, size and stability as a result of consistent exercise

The cardiovascular system, also known as the circulatory system, is comprised of the heart, blood and blood vessels. Consistent exercise lowers both resting and exercising heart rates, decreases blood pressure and LDL “bad” cholesterol levels and increases HDL “good” cholesterol levels.

The nervous system is made up of the brain, spinal chord and nerves. Exercise increases the flow of blood, oxygen and glucose to the brain. In addition, the activity in the muscles keeps the synapses of the brain stable. This increase in flow combined with stability of synapses results in improved memory, concentration, co-ordination, mental agility and focus. The nervous system also controls the communication between the cardiovascular system, renal system and muscular system. This process of communication is valuable for stress reduction.

The digestive system is responsible for the ingestion, digestion and extraction of nutrients from food and ultimately the removal of waste products. Most exercise has a positive effect on the digestive system by helping to suppress the appetite and increase metabolism.

The endocrine system is made up of a group of glands that produce the body's hormones. Hormones are chemicals that control body functions such as metabolism, growth, and sexual development. The hormone insulin is responsible for regulating sugar levels in the blood. The most common cause of diabetes in North America is the decrease of insulin sensitivity in the body. Regular exercise increases insulin sensitivity.

The immune system defends the body against infections and diseases. Organs, tissues, cells, and cell products work together to respond to dangerous organisms (like viruses or bacteria) and substances that may enter the body from the environment. Moderate exercise helps boost the immune system.

The benefits of exercise are evident in all systems of the body. Combining safe, consistent exercise with proper nutrition is the best way to get optimal performance from your body. Always consult with a physician before beginning any exercise program. For help with exercise routines that are goal specific and safe, consult with a Certified Fitness Professional.
