For example you could be super in shape from a muscular perspective but have really bad cardio and vice versa.
How is cardio different from physical shape and what exactly happens in your body that makes you have more cardio?
In: 368
Anaerobic exercises (weight lifting, etc) increase the size of the “tank of gas”. Aerobic exercises improve the efficiency of “the engine”.
When you increase your cardio, you work all the systems that help replenish oxygen & fuel to your cells. That includes increasing red blood cell count, increasing vascular strength, increasing heart health, working your diaphragm which improves lung capacity, improves capillary growth, and especially at beginner levels your form improves a lot which gets you a ton of free endurance by just doing the exercise efficiently
