Hello-new here as well...
I am 30 years old and just had my second baby 9 weeks ago. I also had just lost about 30 pounds and gained it all back and then some. My son had some serious medical problems after birth so I am just now starting my workout routine. I would really like to get back into the 130's by this summer, but I am finding it is really hard to find time to work out with 2 kids now. I go back to work from my maternity leave in two weeks which is going to make it even harder.
I know that the only way that works for me is going to the gym at least 5x/week and decreasing my sugar intake which is so hard for me-I LOVE SUGAR! That is awesome that you are working out with a trainer. I did my first body pump class on monday (first in 9 months) and I still can't sit down my legs are so sore.
Anyways good luck to you, keep up the hard work!

Hope we can keep each other motivated, I know I need it.
