Today we are going to talk a little bit more about fitness. In today's video I have received two questions. The first was regarding Vitamin D deficiency and the second one about extreme workouts.   Although they are not discussed as much as they should be, they are two really important topics that we need to talk about.   Vitamin D deficiency is becoming more and more frequent nowadays, especially due to the lifestyle we are adopting.   Extreme workouts are also becoming more frequent, due to the rise of the crossfit modality and, in fact, it can cause you more harm than you've imagined.   So, wanna know more about these two topics?
