My cardio days: 3 sessions between Friday to Thursday, then Friday, Saturday, Sunday. So 6 to date in the last 1.5 weeks.
I've heard that many people lose a lot of weight their beginning weeks, especially that first week of water weight. So I stepped on the scale (Friday) a week after my first weighing + 3 cardio sessions, and it was up - OK, I had just actually eaten something not too long before, so I figured it would probably go down once the food was digested. Then I got on the scale the next morning (after going to the bathroom, very effectively might I add

) and thought, well maybe I'll see something! But again, no change, just back to what it was when I first started. Sunday I got on the scale and I'm half a pound above what I was when I first started.
I'm trying to take it easy, and I'm doing all right mentally because I know I ate an all right number of calories that week (based on the types/amounts of foods I ate, not calorie counting) - not too great but not a huge amount, so I don't think I could have gained somehow, if that makes any sense (I'm exhausted, sorry if it's a bit confusing). I haven't done any weights, but when I've done cardio I've felt my muscles having a real work-out just to enable me to keep moving on the machine. Could I have somehow gained a little bit of muscle during that short time and have that kept the scale constant? Or did the exercise just not add up to enough to make me lose even a pound?
