Much less volume of poop
I've been noticing ever since I took structured training since a month ago, my daily poop amount started getting less and less in volume. Just by looking at it, it looks less than 50 grams daily average. Otherwise, there's no sign of any health issues nor constipated from the looks and hardly makes any smell.
And then yesterday, I did the longest ride I this year, most of it in the mountains. I did not poop yesterday but I ate A LOT of food yesterday, before, during, and after the ride. That includes lots of carbs and meat. So I skipped a day of poop, ate incredible amount of food. I should be pooping a lot, right? Today (rest day) I pooped but still made less than 50 grams despite all the food I ate! Again, the stools show no sign of issues and not constipated. I even looked at the bathroom mirror and saw my tummy is totally flat like I have eaten nothing. So where did all those poop went? Is this normal to anyone quite physically active?
