more muscle = less stamina
Recently I've been dieting and was thinking about the effects that weight has on stamina.
Basically, the heavier you are, the more energy it takes to move your body. How much of that energy you have is your stamina. When you gain muscle, it adds more weight and also the muscle uses more calories/energy.
So say we're doing number of punches to measure your stamina and you can keep your stamina consistent through every situation.
If you gained a lot of muscle in a short period, your power would increase but total repetitions decrease because every punch would be using more energy. This is due to both being heavier and the muscle uses more energy.
Therefore if you lost weight, it takes less energy to move(because of less muscle & weight) and thus you should be able to do more punches.
Is my logic wrong? Am I missing anything here?
If you did stamina training, you will increase endurance. However, if you only did heavy weight lifting, shouldn't your stamina decrease?
