Drinking Water During Exercise

How Much Water Should I Drink When I Work Out?

  • 32 oz an hour is too much! Even though your body might lose 32 oz of water per hour, it cannot process that much and you'll wind up with stomach discomfort, possible cramping or other side effects. It's a myth that you should "consume what you lose" during a workout. Depending on your weight you should replenish 10-16 oz per hour for vigorous exercise. Our bodies can handle a temporary loss of hydration, but it's important to continue drinking after exercise over the next few hours to slowly replenish what was lost. - 5/22/2009 10:36:54 AM
  • When I am running on the treadmil, I slow down to drink water, usually by the end of my run , I have drank 16ozs of water. Then after, I feel very thristy, and drink about 16ozs. - 5/15/2009 2:07:58 PM
    I definitely can't drink 3 or 4 cups of water WHILE working out for an hour, I would feel so sick... And most days, I'm at the gym first thing in the morning, so I don't have an hour or two to start hydrating beforehand. I just sip at my water during the workout (finishing between 1 and 2 cups in an hour) and then make sure to drink as much as possible the rest of the day. - 4/27/2009 10:01:20 AM
  • I was surprised at the amount. Time to drink more water... - 4/14/2009 8:09:27 PM
  • Love this article, but I get HORRIBLE cramps from drinking water before I workout. I understand getting the right amount of fluids is important, but any recommendations as to how I can get rid of the cramps? - 4/14/2009 12:16:39 PM
  • I didn't realize you lost that much water!! Geez! I don't drink enough water, I know, but this article did help me realize I need to drink more. I do drink water during a workout at home when I'm doing DVD's, but I put it in a glass with ice and drink through a straw, that way I'm not gulping so I can avoid nausea. - 4/2/2009 11:48:41 AM
  • I had a mouth full or 2 b4 going on an hours run today. Couldn't figure out why I was struggling so much....Aaaaaa ha! I do now - 3/31/2009 11:33:42 PM
    Great article - a quart - holy smokes! However when I drink water while I exercise I get side pains that bother me so much I feel like jumping off the treadmill. Anybody else have this problem? If so do you know any ways to combat this...I would love to keep jogging instead of getting off until my side pain goes away, and my motivation with it. - 3/31/2009 5:46:35 PM
    Sometimes it helps to flavor the water with a dash of unsweetened lemon juice. The little bit of flavor makes it something to look forward to -not to mention what ever minute vitamins it might add. Sweetened things make one's body require even more water to dilute and process a solution, but a tiny bit of tartness,for some reason, is thirst quenching. I really put this to the test on more than one occasion when I was doing 50+ mile bicycle rides and needed water more than I had realized...
    *On the other hand, I've read some negative things about lemons squeezed into water glasses at restaurants: something about the bacteria on waiter/waitress hands being transferred onto the lemon skins. - 3/31/2009 4:38:01 PM
    I use a squirt bottle while running on the treadmill. It was hard to get in all the water that we are supposed to have, I'm getting better at carrying a water bottle around with me. - 3/31/2009 12:53:27 PM
    I have to drink about 4 ounces every 2 hours to get it to go down... too much at one time and I get nauseated. - 3/31/2009 10:59:43 AM
    I agree, can't drink before a workout when you workout first thing in the morning, but I do keep a glass by the bed and if and when I wake up during the night I have a drink. When I get up I have a drink then too. During my workout I find I'll sip through that too because I'm feeling parched. - 3/31/2009 10:48:30 AM
    How on earth do you drink DURING a workout? - 3/31/2009 9:02:10 AM
  • "Start paying attention to your fluid intake 2-3 hours before you are going to exercise. "

    What about those of us who workout first thing in the morning? Like 6AM? Surely I don't have to set my alarm for 4!

  • When you first start drinking more water, your body is like a dried up plant: the water runs through the soil until the soil is saturated enough to begin holding the water. For those of you who are concerned about too many potty breaks, it will get better if you keep drinking the water. - 2/24/2009 9:12:35 AM
