Do you weigh more or less after a workout?

I have a 5-6 pound drop after cardio when i burn 800+ calories. Water weight no doubt.

ops ....

Me personally, I weight usually one - two pounds less after working out. I workout for 45-60 min, sweat heavily, drink lots of water. Cardio or weights (which are a fast rate circuit for me)

For my most accurate measurements, I always weigh myself first thing in the morning after voiding body wastes, unclothed.

Keep in mind the many many things that can make one appear to weight heavy, just a few are :
-water retention related to hormones,
-fluid retention in sore muscles when you have increased or changed exercises,
-water sodium related retention due to diet excess the day before (fast food, Chinese food, Free day meals that are carb or sodium heavy)
-PMS or menstruation
-Additives in some supplements (fillers in many products such as createn, drink mixes, pre workout drinks)
-certain medications that effect fluid balances
-food or liquid in your system from recent meals, drinks


So when gauging weight loss, use size of clothing or fit changes, tape measure readings, and overall weight trends over a few weeks. Not changes from one week to the next, which can be less accurate.

doesn't necessarily matter cause it's water and the scale will go back up again within that same day, but for me w/ cardio I weigh less

Immediately following a work-out, I weigh less (I'm assuming it is from water weight I'm losing due to sweating). However, my weight tends to go up a few pounds the following day and for up to 4 days after a heavy workout.

Haven't got a clue...I only weigh first thing in the morning.

Exactly!!

Also even day to day fluctuations should be ignored you should be concerned with trends over weeks and months. If you are worried about you weight fluctuation during the day you may need to rethink your relationship with the scale

This is the deal, it's just fluid. If you could measure the amount you sweat and add that back in and then measure the amount of water you drank and subtract it out, your weight really wouldn't have changed. Make sense?
People who don't really sweat during a workout and drink a lot of water will appear to weigh more.
People who sweat a ton and don't drink a lot will appear to weigh less.
If you take in exactly what you put out, water-wise, you will weigh the same.

Very well said. A running coach I work with recommended that when I'm training and doing long runs, I occasionally weigh myself before and after workouts to ensure proper hydration--weighing significantly less after a workout might indicate that I'm not drinking enough water.

I've never bothered to check. I only weigh myself once or twice a week, first thing in the morning. I know fat isn't burned or gained instantly so what I weigh after a single workout or meal isn't important. Weight fluctuates so much throughout the day there's really no point in focusing that closely on it.

More. I drank lots of water during the work out.

Exactly, and this is why I weigh myself before and after each workout. It helps me make sure I'm drinking enough water while working out. If I don't drink any water I usually sweat off 1 - 1.5 pounds.

Okay, if anything you would always weigh less after any type of training. For one, assuming you drink no water, you wouldn't weigh more due to water retention. You'd end the workout with the same amount of water, if not LESS, than you began. Assuming you drink water during training, you would for one sweat and two surely not drink so much water it would become measurable on the scale. So, if anything you'd weigh less after training, for a short period.

cant honestly answer I only weigh myself once a week

I weigh more. I drink a lot of water, even up to a gallon. No amount of sweating is going to undo that.

Usually sweatin bullets, so less.
It's only water though. I just drink back what I lost.

Just like ROBO and others have said. It's just water. I gain, but lose later when I go to bathroom. Others will lose, but gain when they drink.

If you look at the physiology of exercise, you cannot "weigh more" after a workout than before the workout. You will burn calories in either type of workout. One pound = 3500 calories. The scale may tell you that you weigh more, because of water retention, etc., but since a calorie is a measure of heat, heat that you created during your workout, you lost weight that will not return until you consume replacement calories.
