Being Molly's mom is the greatest joy I've ever known. However, I've learned over the past 4 months that my time really isn't my own anymore and that can make it difficult to do things for myself – like working out. Heck, if I thought I didn't have time to workout before, I DEFINITELY don't have time now. That said, after gaining 40 lbs during my pregnancy, I knew I wanted to make fitness a priority. Not just because I wanted my pre-body body back (although that was definitely a motivator), but because I want to be as healthy as I can so I can live as long as possible to be here for Molly. So today on the blog (click link in bio), I am sharing my fitness tips (like this @Withings Steel activity & sleep tracking watch!) for everyone reading this who has very little time but wants to get shape! Making little changes my life, helped me get fit and I know it can help you too! Hope my blog inspires you all to be a little bit more active in your lives! P.S. there is also a code on my blog for 20% off @withings fitness products!
