Cardio can be used as a great way to help anyone get into better shape. It is a good way to burn calories, and it improves your cardiovascular health. Many people out there are wondering what the best form of cardio is that will help to get them ripped. Some people might think that sprinting is the best form of cardio, while others may think that it is walking.
I am here to tell you that there is no "best" form of cardio. It is really just a personal preference on what it is that you like to do. If you like to go out for nice walks around your neighborhood, then that is your best cardio. This is because you will stick to it and not quit, you will be consistent with it so to speak. If sprinting is not enjoyable to you and you hate it, then you will likely end up quitting and not doing any cardio at all.
Some of you still might be thinking that sprinting is better than walking or jogging because it burn more calories. This is actually not true. If you walk, jog, or sprint 100 yards, you will burn the same amount of calories. The only difference is the time factor. You will spend a lot less time if you sprint or jog the 100 yards as opposed to walking it. This is why some people out there like to do high intensity interval training (HIIT) because it can burn a lot of calories in a short period of time. Doing HIIT is absolutely fine as long as you stick to it. On the other hand, if HIIT is too intense for you and you have the extra time, then you can walk and burn just as many calories.
It is also true that HIIT releases free fatty acids into the bloodstream. If you then followed the HIIT with a slow steady state cardio like jogging or walking, you would then burn off those free fatty acids released into the bloodstream. This is a great way to do cardio, but it will only work to burn fat if you are in a caloric deficiency at the end of the day. This is why it does not matter if sprinting exercises more fat burning hormones. If you are not in a caloric deficiency, then any form of cardio will not do you any good. This is why I like to think of cardio as a tool that you can use to get in shape. Cardio is not a crutch that you have to rely on at all times. If you have a solid diet plan, then you can get in shape without cardio. At the end of the day, the best form of cardio is the cardio that you like and will continue to do.
