At least 8-10 water bottles a day.
My trainer tells me to aim for drinking half my body weight in ounces.
Truly, there is no one answer to this. All recommendations are based on an average person, but no person is average. For example, if you sweat a lot, obviously you need more water than someone who doesn't. If you exercise a lot, you need more water than someone who doesn't. If it's hot you need more water than when it's cold. Etc. The longest lasting recommendation has always been to drink when you're thirsty, but if you're cramping it's a sign you're either drinking too little or not getting your electrolytes. It's also true that different cultures have very different theories of water -- Oriental medicine isn't that keen on water, whereas in the West, where water is a commodity, the recommended amount keeps going up regardless of the person's individual nature. Curious, eh?
The total body water represent 60% of the body
So the water is so important
They say 2L to 4L is essential per day
For me I go with 2.5L , at the beginning u will see it that hard to drink that amount of water but try to divide ur day into intervals and u can drink 1 bottle in each one, there is small bottles which almost 330ml or medium one with 650 or 700ml for me I choose the smaller one so u can drink it easily and quickly without pushing ur self
Thanks I hope that is helpful
Around 3 to 4 litres a day
