I used to watch the show and felt motivated at times to push myself to extremes then to give up. I would start getting discouraged that this is who I was meant to be....large.
They push people hard and you see the struggles. I have always worried about those that felt the same as me....like they couldn't do it and just decide to give up without trying.
I'm so thankful for shows like "I lost it" and "X-weighted," I was so motivated when I started watching the show that I made it a point to exercise everyday while the show was on (1 hour). I started with my Wii Fit Step workout, where I could watch the show as it was tracking my steps. From there I did other stuff as I was able to move better.
Now I use my treadmill as I watch the show. My dh tells me that I don't need that show anymore but I still find the motivation I need to not fall back to old habits.
