I had a baby a year ago and also had my tubes tied. I am ready to get back into shape I am in the 3rd week of p90x and I also do zumba a few days a week. I am at 129.2 goal weight is 115. I am more concerned into gaining muscle then anything else. But would like to have a lean muscle mass. If anyone is doing p90x as well add me. We can motivate each other!
