Is losing 5 lbs. during a workout normal?

I'm 6'3". I swim. :shrug:

1. That must have been one hell of a workout.

I've heard of wrestlers drinking a gallon of water before weigh to meet the requirements. I guess if you were full to begin with and lost a lot of water weight, maybe.

4. I swam 30 football fields...

then sat in a jacuzzi for 20 minutes. Then lifted weights for another 45 minutes.

And did pee.

But didn't drink any water. If it's water weight, does that mean I lost 4 lbs. of sweat? BTW the scale is deadly and depressingly accurate to the nearest tenth of a pound. It cuts both ways.

5. Weigh yourself again tomorrow.

After you are re-hydrated and about the same time after you last ate today.

I know someone who is losing almost a pound a day through intense dieting and working out, 5 lbs in one workout can't be all fat.

6. You're absolutely right

I chronicle it, actually. Yesterday I lost 4+ lbs, and gained it all back today, same time.

Today, it just happened to be 5 lbs. I'm just wondering how from a physiological sense, do 5 lbs evaporate in 2 1/2 hours? Anyway...appreciate any insight. Thank you.

7. YW

Being surrounded by water, you probably don't realize how much you are perspiring while in the pool and jacuzzi. 1 gallon of water is 8.3 lbs. So you lost a bit over half of that. That doesn't sound unreasonable for a intense 2 1/2 hours of exercise.


GL with your workouts.

2. It is unlikely that you burned 17,500 calories in one workout.

It is probably due to water loss. Or a dysfunctional scale.

3. Did you pee and sweat 1/2 gallon+?

That sounds like a lot, but as long as you're staying hydrated I wouldn't worry about it. (Note: I have absolutely zero knowledge or expertise on which to base that claim.)

Are you sure someone didn't 'adjust' the scale during your workout?

8. Only if body parts have fallen off. n/t

9. At 6'3", I would guess that weight fluctuations within 5lbs are normal

It is most likely water weight that you lost - not fat burned. tho - I'm sure with that workout you did burn a lot of calories, still, 5lbs in one day is mostly water weight/normal fluctuation. My weight fluctuates within 5 lbs regularly and I'm only 5' 3".

10. If you stop after a few laps to take a massive dump, sure.

11. My thoughts exactly!
