1- Strengthens heart muscle.

-    -      Strengthens heart muscle.

-          When exercising the level of intensity increases our heart rate. Imagine as we do squats our quadriceps fill up with blood like a sponge, and then as we contract the muscle it pushes all this blood up to our heart. This blood then needs to be absorbed by the heart as it enters the right atrium and through to the right ventricle. At this stage the right ventricle fills up with blood like a sponge but then needs to pump all of this blood out into our lungs for re-oxygenation. The more blood that is pumped into the heart from the other muscles during exercise the more the muscle belly of the right ventricle fills up. This means that it is under a greater resistance to push the blood out and complete the cycle. Our heart muscle is much like the rest of our skeletal muscles. In order for our muscles to improve in strength we need to exercise them against a greater resistance. In the case of our heart, this increase in blood flow is the resistance to improve our hearts strength. As this cycle repeats, our skeletal muscles (like our Quadriceps) are now requiring more blood and thus our heart will become stronger to supply our quadriceps will the amount of blood and oxygen it requires. A stronger heart will improve all areas of health and fitness in our body, proving to be a great reason as to why we should exercise.
