Not getting results

I started exercising again.  Last week, I started doing one 10-minute segment of a pilates workout each morning.  The video is called Weight Loss Pilates, and I am doing it more for a workout than for weight loss (breastfeeding has always eventually gotten the weight off for me, so I am not obsessing about that).  The third day, I did the third segment, and the video ended.  I had completed 3 days of 10-minute workouts.  Hannah, who had, of course, been observing my workout, said, “That’s the end?”  I told her it was. 

“I don’t think you lost much weight.”
