We all know that we should be trying to drink 2 litres of water a day - right?
Did you know that, for every 15 minutes if brisk exercise we lose 150ml of water through perspiration and breath!? So for an hour of exercise we need to take on board an additional 600ml.
Its tough to remember to do it though and we tend to remember, gulp down a pint and then rush to the toilet.
Here's a tip, fill up a 2 litre bottle and sip throughout the day so that you are left with a glassful for bedtime. Add to this a separate bottle for your workout.
Gulping down the stuff is like over watering a dry plant - it just pours through the soil - better to drip feed it until the soil has absorbed it all - we're just the same!
