So yes bhai, what happens is, if the session is short, then there's no problem because we get sodium from the food we eat. So you can drink normal water. But if the session is long, then whenever you do a long session, you should measure your body weight before the session and after the session. If there's more than a 1 kg difference, that means it was a serious session. And for every 1 kg of water loss, you need to drink 1.5 litres of water with electrolytes. So 1.5 litres with electrolytes, okay? You can drink some of it with electrolytes and the rest can be normal water as well. So that's the concept. – at Noida, India
