Exercise does much more for you than its effects on the heart directly.
Yes it improves your heart health if you are doing a cardio workout, but tt prevents heart disease in other more significant ways. Here are what I believe to be the most important:
Exercise is the biggest weapon to fight stress. Stress leads to many conditions including heart disease. When you are stressed, your adrenals react by releasing cortisol. Cortisol tell your body to increase blood sugar, which subsequently tells your body to increase insulin.
In the presence of insulin, your body cannot metabolize fat, but rather stores it. This is an environment where vLDL is produced aka triglycerides. Triglycerides are what form the plaque within your arteries which lead to heart disease.
2. Speeds up TCA cycle.
Why does this matter? Well I just outlined how blood sugar and insulin lead to heart disease. Your TCA cycle is the ability to convert sugars into energy. When you overload your body with carbs, your TCA cycle gets backed up. To work faster, it converts the carbs into the vLDL that was just mentioned.
Exercising makes the TCA cycle run much faster, which helps prevent weight gain and vLDL production. Most people think exercise makes people lose weight because of the calories it burns.. couldn't be farther from the truth.
