Started Beachbody (sorry long story)

Hello everyone I am new to this group and already I have really liked seeing alot of your progress photos, it gets me motivated! I just had my daughter in June and while I was pregnant I gained alot, I was 170 prepregancy and then I reached my highest at 255 at 9 months. After I had my daughter in June I automatically lost 10 pounds so I was down to 245 but stayed that way till August when I started slim fast replacement shakes. I drink one each morning and now i am down to 210 so I lost 35 pounds so far but still in order to be at my healthy weight for my height I need to be 130. I haven't been 130 since I was 18 and now I am 33. After I had my oldest daughter, who will be 5 next month I remember looking at photos of myself 2 years after having her and was disgusted with how I looked. I ended up doing Medifast and lost 30 pounds but still I was at 170 and just stayed at that weight till I got pregnant with my youngest. I dont want two years to go by again and still weigh 200 pounds. I started beachbody yesterday and boy did it kick my butt. I am excited to do it today but the problem I always run into is being to tired to workout eachday and I wish I didn't feel that way. How do you guys stay motivated to workout eachday, so it helps me stay motivated? I am excited to share my progress with you guys so please help encourage me, thank you! ❤
