I wear a pedometer every day. Have you heard of the 10,000 steps a day program? I have been doing this for 5+ years. I try to get between 10 and 15,000 steps a day. I also do pilates or core secrets between 3 and 5 times a week. I have slacked off a little and I have had a lot more back and shoulder pain (lifting DD at 75 lbs contributes to that!)
I totally understand about the clothes not fitting how they should. That is one of the things that got me started. Also, knowing that I needed to be able to lift and care for DD has been a motivator. I can't really go to a gym, so I have to be my own monitor on this.
Oh and how tight my jeans fit!
