All of us are aware that we need to replenish our body with fluids to keep it supple and healthy. Dehydration occurs when the body loses more fluids than the amount taken. A 24 hour fitness program can be followed but keep in mind to replenish your body with water and other fluids like a low calorie fruit juice or yoghurt, energy drinks and so on. Any kind of physical exercise will drain out the fluid content in your body. It is important you do not overdo the fitness program and get into any serious health challenges. Always follow the guideline as given by your instructor.
