Why warm up & cool down??


Warm Up

The main purpose and benefit of warm up exercises is to slowly increase your heart rate. This increase in heart rate helps to raise your body temperature and to increase the blood flow to your muscles.


This increase in blood flow properly oxygenates your muscles and prepares them for the upcoming more strenuous aerobic exercise. With your body properly warmed up, you can easily and safely perform the needed stretching exercises to ensure proper flexibility and range of motion for your exercise routine.

A warm-up helps you prepare both mentally and physically for exercise, and reduces the chance of injury. During a warm-up, any injury or illness you have can often be recognized, and further injury prevented. Other benefits of a proper warm up include:


  • Increased movement of blood through your tissues, making the muscles more pliable.

  • Increased delivery of oxygen and nutrients to your muscles. This prevents you from getting out of breath early or too easily.

  • Prepares your muscles for stretching

  • Prepares your heart for an increase in activity, preventing a rapid increase in blood pressure

  • Prepares you mentally for the upcoming exercise

  • Primes your nerve-to-muscle pathways to be ready for exercise

  • Improves coordination and reaction times


Cool Down


Although many people skip warming up and cooling down, the cool down step is probably the most overlooked piece of an effective exercise routine. The benefits of cooling down are just as important as warm up period but bring you different benefits than the warm up routine.During an aerobic exercise routine you are working your heart within your target heart rate zone. The main purpose of cooling down is to bring your breathing, body temperature and heart rate back to normal slowly.


During the cool down routine you are allowing the blood to properly redistribute itself to the heart. This redistribution helps rid the muscles of lactic acid which can build up around the muscles during an aerobic workout.


If you stop your aerobic exercise abruptly and do not cool down, the blood can pool up around your muscles in the legs. This can cause insufficient blood flow and oxygen to the brain giving you a light headed and dizzy sensation. Dizziness, nausea and feeling worn out are common symptoms of an improper or no cool down period.
