Water?
 

.

drink if you want to.
dont drink if you dont want to.
drink whatever temperature you want.

You should drink before, during and after working out. During exercise it is perfectly ok to take sips of water but I wouldn't think that filling your belly up with water and then doing some heavy cardio is a good idea. As for the temp of the water, there are all sorts of myths out there about it. Personally I prefer cold water after cardio and in the summer time and room temp water when doing weights or anything else. It's really an individual and personal choice...

I drink water while I work out if I feel the desire to do so. Replenishing my fluids is important, and like the others, the temperature of my water is personal preference - sometimes cold, sometimes room temperature.

I carry a water bottle with me and use it all day long. It is an easy way to stay hydrated.

If I don't drink regularly while working out I get horribly dehydrated and get a headache. This is especially true with cardio but I drinking while lifting too.

I drink more with lifting than I do with cardio. Never thought about it before.

This.

Really--there's no magic. Listen to your body.

I usually sip on water throughout my workouts. My preference is ice water but it may not be for everyone :D

It's pretty individual. I read running advice about not needing to take water with you unless you go more than, I don't remember, was it 45 minutes or something like that? Anyway, I always took water with me, and drink it from the beginning (in sips). I feel thirsty! It's most definitely not ice water in the winter! Maybe cooled water in the summer, but even then not icy when I'm running.

I try to drink water throughout the day. It makes me less thirsty when working out and I believe keeps me better hydrated than trying to get a lot of water in during a workout.

I'll sip water when I feel the need during weight training. When I go run I don't carry water with me. I only run 2-3 miles, though. I've heard when you get to the point of 5 miles + you should bring some fluid with you.

YMMV

This is what I do. I drink 71oz of water every day (3 water bottles full).

i drink about 8 glasses or more of water a day...before i work out, i drink half a cup, during exercise (an hour cardio) i drink the whole bottle, and after i drink a cup.
i find that when im exercising, i feel more replenished and energized with ice cold water...

I drink small sips of water when working out. If I drink too much I feel "weighed down" and sluggish. After my workout, I usually drink a whole 16oz bottle.

I also prefer mine ice cold. :D
