And more importantly, should you??

Tom Brady, quarterback of the New England Patriots, widely considered to be one of the greatest quarterbacks of all time, has a message for you: drink more water.

A lot more water. In fact, if you want to keep up with Brady’s own water intake, you’re going to need to consume 37 glasses of water per day.

That’s a lot of water.

How much? For context, imagine a gallon jug of water. Imagine you’re holding a gallon jug of water in each hand. Imagine that you drink BOTH of those gallons — and then you drink another third of one, just for kicks.

Or, if you’ve ever seen an office water cooler, complete with a blue five-gallon reservoir mounted on top? Imagine pouring out half of that — and then drinking the entire other half.

Where’s this come from? In a book he wrote in 2017, the Patriots six-time Superbowl champion stated that he drank ‘half his body weight in ounces [of water] each day, and double that amount when exercising.’ Brady states that he drinks up to 300 ounces of water each day when he exercises — that’s about 2.3 gallons.

Now, this definitely seems to be working for Brady; I don’t have even a single Superbowl ring, so I can’t challenge him on his results.
