It is important to drink plenty of water before and during a heavy workout because keeping hydrated

We depend on water to survive. Every cell, tissue and organ needs water to function.  Our body uses water to regulate our body temperature, aid digestion, transport nutrients, lubricate joints and remove waste.

Water is needed for good health and a strong performance in the gym or when training anywhere. We lose water over the course of the day, not only from going to the bathroom but from sweating and breathing! We will lose water even faster when it’s hot or we are physically active so we need to replenish to stay hydrated.
