✓Make An Inspiration Area

It’s also amazing to create a space devoted just to you and your spiritual goals. Whether it’s for your yoga practice, goal setting, or meditation, make a space just for you. Frame some of your favorite pictures and inspirational quotes to hang on the wall (I have a chalkboard where I write all my intentions).

✓Organize Your Gear

Think about what outfits make you feel the most confident. What inspires you for your workout? What will motivate you to run that extra mile or do that extra rep? Put those clothes front and center! Create a space in your closet where you can set out your fave yoga pants, tanks, sports bras, sneakers, and socks. This makes it so easy to grab your gear when you’re running out the door for your Booty Call!

  8. We are all so happy for you Kat, and you’re going to be the best Aunt Karena!!!
    Are we only going to have access to the specific Bikini Series workouts through the app?? If we can’t get the app since you’ve only made it available to IPhone users, is there anyway we can purchase the workouts separately like we have done all the years before? I’m just a little confused…

    1. Thanks so much babe! Awww love that idea! I can’t wait to share my journey and tips with you 💖

  10. I’m sover the moon about all this news. Katrina and Brian are going to be great parents and Karena is going to be the best auntie. This baby has no idea the level of love he/she has already. Huge congrats!

    1. I’m over** the moon about all this news. Katrina and Brian are going to be great parents and Karena is going to be the best auntie. This baby has no idea the level of love he/she has already. Huge congrats!

      1. I would have to agree on the love. I am already jealous that I am not the TIU baby with all that love that is going around. Jk….well kinda ;) BUT I’M SO EXCITED FOR THEM!!!!

  11. My heart is full of many joys but the biggest one is that you are starting to expand your family! Hooray for TIUBABY!!!!! Congrats Katrina & Brian ….also Auntie Karena :) The Bikini Series is just a bonus too ;)

  12. First of all: CONGRATULATIONS! From the moment I learned about Tone it up, at the beginning of this year, you’ve given me so much inspiration, a positive boost and so much focus on the important things in life (living and enjoying it to the most – which I’d strangely forgotten)…Just imagine, if you can do that for someone who doesn’t even know you in person, how much of an inspiration you’ll be for your child(ren), those who’ll get to feel your positive vibes first hand. With all the love you (all of you) send in to the world, I am sure your little one couldn’t have chosen a more loving family to be born in. <3 Enjoy every moment!

    Now…I do still have a question; every day I work out in studio Tone it Up, it's so motivating to see and hear all the moves explained to you, and to feel the energy of all you trainers. I however struggle with the daily moves (basically because no-one is talking me through it). For the success of the bikini series; is it necessary to do the daily moves AND a studio class? Or can I just do take the classes? Orrrr, do you suggest I take two classes to make up for not doing the daily workout? I come from a place absolutely hating to work out, so I'm not really good at intuitively feeling what's right for me to do :/

  13. I feel like I have been waiting soooo long for you to have a baby!!! haha! I remember sitting in Miami at the retreat when it was brought up! So excited for you all! Babies are amazing!! #Momof3 #TIUhelpsmelosethemombelly ;P

    1. Yes!! Your clean, plant-based, non-GMO Tone It Up Organic Protein ships internationally! You can grab it HERE!

  14. I’m so excited for the bikini series, this will be my first time ever. I just purchased myself the new lifestyle kit yesterday.

    By the way as a member where do I see the bikini series for this year? Will it be emailed or do I have to check here on my TIU?

    1. Hi babe! So excited to start your first Bikini Series with you and for your new lifestyle kit! You’re going to LOVE it! We’ll be emailing you your new 8-week Bikini Series Edition a few days before the challenge kicks off and you’ll also be able to find it here under “My TIU” 🤗

      1. Last question

        For the bikini series workout will it only be available for the TIU app subscribers? (I do have the app but I haven’t subscribed to the studio yet)

        Where do members get the bikini workouts? Or will it come along with the meal plan that you guys will be emailing the members?

  15. Congratulations Kat!!! So exciting!! I cant wait for this Bikini Series! We are all going to be looking and feeling like bombshells!

  16. WOOOOOOWWW!!! Congrats from Germany for these great news!! This is sooooo special and you two will be absolutely great parents, don’t worry! :) It is really funny, I never met you guys in person, but it is as if a girlfriend of mine told me she is pregnant and I’m absolutely happy :) Have a great pregnancy and enjoy every Moment! Lots of Love! <3

  17. Congrats Kat and family! I started TIU exactly 1 year ago – when I was about 20 weeks pregnant! I absolutely loved doing the workouts and did them up unit the night before I gave birth to my beautiful little boy. TIU was key in helping me have a healthy pregnancy and being a fit mamma. Wishing you the very best in your pregnancy, Kat!
    PS: Bryan, you should read The Birth Partner by Penny Simpkin, it’s amazing and will help you give Kat all the loves during labor!

  18. Congratulations Kat and Brian!!! Your seriously going to be soo cute prego! I do have a question though. I’m all about health and fitness but sometimes there are times that I don’t have time to cook or meal prep and I turn to a frozen meal. I know they have tons of sodium but what would be your recommendation for the best/healthiest frozen microwavable meal out there?

  19. Hi, I am a member however did not get the starter packet for the bikini series in my email yet though I signed up for the bikini series…thanks!!

  20. Hi! I need help please! My hands and fingers are damaged so I can’t hold dumbbells. Anyone knows if I can replace them with wrist weights instead for the daily moves? Many many thanks, I am really excited about the Bikini Series 🍍🍍🍍☀️☀️☀️❤️❤️❤️xxxxx

    1. Hi babe! You can absolutely modify moves and we recommend reaching out to your doc or physical therapist just to make sure it works best for YOU!! xxo

  21. The number one thing I need to know from this post….. Where did those pink and palm swim suits come from?!?!!?!?!

  22. HI! I just bought the Lifestyle Kit- where can I access the Bikini Series Guide for this challenge? It looks like the one in my downloads is from last year.

    thank you!

    1. Hi babe! We’ll be sending you your new Bikini Series Edition next week before the challenge kicks off. Keep an eye on your inbox! xxo

  23. I finally did it (after many years of just browsing on this website :() ! Joined the bikini series and nutrition plan program! Nervous but still excited! lol

  24. A TIU baby is SO exciting!!!!!! Congrats to Kat & Brian!! 💕You’ll make amazing parents!!!
    So excited to start my 4th Bikini series! {& May 7th is my 39th bday~so better yet!!😉}
    Can’t wait to rock this one!!!

  25. Can’t wait for the Bikini Series!! Would love a new kettlbell workout as well if possible!!

  26. Quick Question!!
    What’s the difference between just the Lifestyle Kit ($67) and the Nutrition Plan + Lifestyle Kit ($170)? Do they both come with the book of recipes?

  27. Right now, I just cannot afford the Studio (I wish I could… ugh… priorities). Will there be anywhere else to get the videos that go with the daily moves? Thanks babes!!

  28. This will be my first TUI challenge and I’m super excited to get started!! When will the Vegan plan be available?

  29. I can’t wait for the Bikini Series this year! I just signed up for the nutrition program! I was reading through the whole kit and and wanted to know if you would recommend prepping the Meta-D or Bombshell Spell ahead of time for the week or if mixing it fresh each morning is the way to go?

  30. Excited for the Bikini Series! Quick question: can you make Meta-D / Bombshell Spell ahead of time? (e.g. with meal prep on Sunday)?

  31. Will there be bikini series video downloads available for purchase like in the past? The app is a great idea but i just can’t afford a monthly payment right now.
    The bikini series is so fun! Thanks girls!
    And congrats Kat and Brian on the new baby!!!

    1. Thanks babe!! Totally understand ~ as always, we’ll have free workouts every Tuesday during the Bikini Series for Tone It Up Tuesdays! PLUS more bonus days this year!!! Keep a lookout 🤗 And always, we have complimentary workout options every day on your Weekly Schedule and Daily Workout page. xxo

  32. How do you prep or batch the Meta D or Bombshell? Is it just a matter of making more of the recipe, or are there some ingredients to wait and add the day of?

  33. Hello! I have started to work out a week ago so I will be finishing the bikini series a little later than you. I have a question though. Is it normal to blow up like a balloon after a week of working out and following a healthy nutrition plan? I was not working out at all before so I am hoping I will get back to normal after a couple of weeks or so. Is that right? Am I doing something wrong??

    1. Hi beautiful! Bloating is completely normal and happens to all of us as women. To de-bloat, make sure you’re always sipping on water. It’s SO important. Staying hydrated raises your metabolic rate and flushes out toxins. We also like to sip on detoxifying ginger tea and eat lots of de-bloating foods like asparagus. Journal your meals to hold yourself accountable and check in with your TIU community for support. We’re always here for you and we love you 💛
