Trying to make sense of some fluctuations I'm seeing (not bothering me, just trying to find the triggers for retention). I noticed that when I do my strength training in addition to cardio, my weight pops up a couple of pounds the next day, then goes back down when I do just cardio. I'm thinking it's water-weight maybe -- is it possible that my body is temporarily holding on to fluid from being pushed to work in ways it hasn't been doing? I've only been doing this for a week or so, so I'm pretty much brand new to the machines.
The other possibility is diet, but I noticed this happened regardless of what I ate the few days I measured it.
Just wondering if it's a possibility.
(And yes, I know weighing every day isn't something you necessarily want to do with weight loss, but I'd like to get an idea of what my body's natural cycles are with regards to weight, so I'm watching it for a while).
