![]() However, performing an extremely high-intensity exercise, such as weightlifting, can deplete our ATP stores extremely fast. These differences in average speeds are all due to the body's ability to produce sufficient supplies of ATP, as our bodies are only able to produce so much in a certain amount of time. Basically, the intensity must lower as the duration increases think the 100m sprint, 5k run, and marathon. Literally, every single muscle contraction must have ATP to power it and if there's none to spare, muscle contractions stop.Įveryone knows that there is an inverse relationship between the intensity of exercise and its duration. Even when you see athletes eating during long races, those nutrients will be broken down through a series of reactions until they eventually produce ATP. ATP has been given the title of "our bodies energy currency" as it's our bodies' true source of fuel at the molecular level. When we train with high intensity, we can significantly reduce our bodies' stores of a compound known as adenosine triphosphate, or ATP for short. It's so important to know why we rest so that we can start taking this interval seriously. I’m not really sure (nothing wrong with being honest!)Īnd to be clear, this is not to make fun of wrong beliefs this is to point out the mass confusion that surrounds a critical training variable that can significantly affect the outcome.This question can actually invoke a lot of different answers. ![]() So how long should you rest between sets? Well, that depends on several factors, but before that, we need to understand WHY we rest. On the other hand, it was believed that longer rest breaks were needed for strength and power training as the body required greater time to recover from using heavier loads. This would then result in more repair being needed, which would mean more significant growth. For example, it was thought that shorter rest breaks for hypertrophy training allowed a trainee to "break down" the muscle to a greater extent. These rest periods were initially given as it was believed that they were needed to optimize the training. Regardless, none of that even matters as no one ever explains why we rest for those periods, and when it is, the answer is usually wrong. Now to be clear, the above times are just to give you a basic idea, and they could differ depending on who you speak to. Traditionally, rest periods looked a little something like this: "Rest" is a training variable that dictates how much time we wait between sets.
