Cut back on . Pack lunch a few days a week. Prioritize self-care (for real). Many of us are working our way toward healthy goals like these, starting this week. And while you may think celebrities, with their super luxe lives, don't catch the same new-year-new-you bug, think again! The famous women below have vowed to get fitter, exude confidence, spread positive energy, and more in 2017. Even better, their Instagram accounts offer A+ motivation for anyone who could use a little spring in her step. Take a look for yourself, and get inspired to finish whatever it is you're starting this year.

If you want to stay on track with exercise…

Start by checking out Kate Hudson's Insta feed. The actress and Fabletics creator has promised to document her first 10 days of the new year as she gets back on track with her healthy routine. You'll also find evidence she's human: Day 1 involved Bloody Marys.

Day 2 she geared up to sweat it out on a Peloton bike.

#rainbows have always been my sign that great things are coming. At first it was just a teeny splash of color-I prayed God would show me a full one & he did. 2016 was filled w/highs and lows -we all have them..from getting engaged to my partner @undergaro of 18+years on the @sternshow to my mom being diagnosed w/stage four glioblastoma. As @tonyrobbins says "life is happening for us not to us." It is truly only the dark moments that allow us to see the light. Even my worst nightmare has shown many blessings. We all approach a new year with hope & excitement..it's a great reset, we can start fresh. I go into 2017 with a mission-to help my mom get healthy & strong first & foremost , get married, start a family, take some risks & help fellow females gain further success, strength & happiness. I want a creative & free 2017, surrounding myself with like people who lift me up & see me for who I am. my mission is to be unapologetically me in 2017! I have an amazing team assembled. we are gonna do some exciting things that you wouldn't expect that I believe will benefit all- especially women. We need to lift each other up-and will. Just wait. Remember-Everything we want is on the other side of fear. Or a 🌈 😀 go to Maria Menounos.com to register for our conversations with Maria newsletter.
