Thank you so much!! You should start a journal! It's a great thing to do so that you can track your progress and other people can follow it. If you don't have a training partner I'm sure there are lots of people in the gym willing to take a short video for you
I'm health conscious when it comes to the boys as well but I try to introduce them to a large variety of foods and they get treats here and there as well... No food allergies for them luckily. Sounds like your training is going well and you're right about the diet, you can only make so much progress if your diet isn't on track. Have you used any of the Biotest supplements to help you with your goals? They are AMAZING! When you finish breastfeeding and get your regular diet back on track I would highly recommend to try indigo and Se7en (if you haven't already), the fat will be melting off!! I am in love with these, I set a goal infront of my eyes in regards to fat loss and conditioning and I'm reaching these goals so much faster than ever before.
I've heard a lot of good things about Bret Contreras and I hope the program will work well for you, it sounds like you are definitely gaining strength back... I'm sure you'll be back in shape sooner than you think, just keep plugging away at it and you'll reach your goal. It's not the easiest thing in the world when you're a mother of two and I have major respect for you to be so motivated to get back at it. I can't stress enough how you SHOULD take lots of pictures now because you need to see your starting point or else you won't be objective to notice the changes that are happening with your body. You'll want something to look back on. I wish I would have taken more photos but I didn't like how I looked then and wanted to wait until I got back in shape so I regret this now.
Good luck and keep me updated with how everything is going! If you start a journal let me know, I'd love to follow your fitness journey with you!
