The Bikini Series kicks off this Monday, April 24!

This Bikini Series is all about taking it back to where it began. After scouting exotic locations in July, we decided to bring it home, Manhattan Beach. This is the place that brought us together, where we became best friends, and where we started chasing our dream to create the #TIUcommunity. So as we’re about to embark on this Bikini Series, we’re taking a moment to look back at how it all started.

Okay…so we know this is so crazy, but we came up with the idea for the first Bikini Series the night before we shot it!! That’s actually how most of our ideas happen. We remember thinking–we need to do a long series of workout videos that motivate the community for summer. So we called Leckrone up, and told him we were going to shoot 8 videos in front of our house. In the morning, we went to the store and grabbed some pineapples, watermelons, and packed up our floppy hats and we made our way to the beach! Some of the best ideas β€” the ones that change your life and the lives of others β€” can come out of the craziest, most unexpected moments. Anyone else feel this way?? Comment below!!! We shot the entire first Bikini Series the week before it was released. And just as we were about to send our first email about it, we thought, β€œWouldn’t it be fun if we named our morning workouts Booty Calls…like when we call on our girls to work their booty?” Just like that, inspiration struck and the Booty Call was born! πŸ‘

Tone It Up Bikini Series 2017 Karena Katrina

Not much has changed since that first Bikini Series, but the good news is, we don’t shoot our workouts the week before anymore!! We actually decided to shoot in Manhattan Beach in July and shot this Bikini Series this past fall, because we wanted to make sure everything was perfect and on point for you. In the beginning of ToneItUp, we only had one workout video and one recipe per week. Now, we have so many editions of the plan, tons of new workouts, Beach Babe videos, thousands of recipes to choose from, and inspiration and advice every single day. We’re also able to connect with you in real time every day on Instagram Story and Snapchat. We’re always working on creating even more new, exciting videos and tools to help you succeed, all the time! We’re so grateful that you are our constant motivation, our drive, our inspiration, and our #1 supporters to keep working hard every day. Thank you!

We can’t wait to start this Bikini Series with you! We’re all starting together Monday!! Sign up HERE and let’s do this, girl!

  14. So sweet the throwback! You girls’ friendship & the love for health & fitness you share is just amazing! And since “you’re going back to where it all first started”, I think it would be great if you include some of the workouts from your first bikini series into the weekly schedules too! Maybe a throwback Thursday?πŸ˜€πŸ˜†πŸ’ͺπŸ’ͺπŸ‘πŸ‘πŸ‘™πŸšπŸΉπŸŒž

  26. Hi! I haven’t received the Bikini Series Nutritional Plan in my email yet. Can you please try to resend?

  27. I haven’t received the Bikini Series Nutritional Plan in my email yet. Can you please try to resend?

  28. Aw! This video makes me so emotional! It is so amazing how far your girls have come, and how much everything has evolved. Thank you for all your hard work as always! This year is going to be amazing!

  29. Funny! Back in the mid 1980’s, the days of the VCR, I had the idea to shoot a workout video, but I just didn’t have the means to get it out to the public…lol…thank you to you both and your team for making things happen !!πŸ‹πŸ€—πŸ™ŒπŸ»β€οΈ

  30. So I’m pretty new to this community, but I honestly have never felt so JOYFUL about taking on a (diet/exercise/lifestyle) challenge like this in my life. (Granted, I’m pretty scared about failing my own expectations here too, but that’s another story.)

    Girls talked about “feeling all the feels” above watching the vid, and I gotta say, I’m feeling them too. There is something freeing, happy, light, Cali-dreaming about it, and this whole TIU thing (that’s #TIUthang), which already feels wonderful… and right. XOXO

  31. I’m so excited to start this journey as a new member! I’ve been doing the free workouts since January, but I’m finally in! So excited to be on this journey with you all! Especially being a south bay girl myself (Grew up in Redondo and now living in Hermosa Beach) I found this the most fitting Bikini Series ever! Here’s to a new chapter! <3

  32. So excited to begin!! Had a rough winter and I can’t wait for monday! One of the reason I love TIU is because you girls are so real!! You just live your dream and share everything with generosity. You are not perfect and assume it. You even laugh about it! I love that! ;P Thank you for all you do for us! :D

  33. Commiting to the entire challenge! Where is that white one piece bathing suit Karena is wearing in the video from? I love it!

  34. Love this song! Did some research to add it to my playlist… for all those wondering it is “Rewind” by Wingtip :)

  35. I’m so excited to be part of this community. I have never been able to stick to a home workout. I love the motivation that you guys always provide. As a busy mom, I need all the encouragement I can get. I’m so exited for my first bikini series!

  36. LOVE LOVE LOVE what you ladies have done. Thanks so much to you and your wonderful team for all the help this week with getting everything working and on track to go!!!! You guys are amazing :)

  37. This is the best! So so fun!!! How do you girls keep getting better with age? …. bootycalls and bikini seriesπŸ’•πŸ˜Š

  38. This video has me pumped for the #bikiniseries! I cannot wait to try all the new recipes too. YUM! What are some of the brands of clothing you have featured in the videos? I’m always looking for good workout clothes and y’all’s are are always amazing!

  39. Yes!! TY for putting together this amazing program and spear heading a movement of women supporting women! I’m a long time member…but will be my first bikini series that I am totally committing myself too! Can’t wait! πŸ’—

  40. I am so excited to have found ToneItUp! I love waking up to see what workout you have put together for us. It is almost like Christmas every day. It feels so good when I realize I can do an exercise that I couldn’t before. I love feeling strong, and ToneItUp helps me feel that way! <3

  41. I love this video! The music, the present and past clips and of course you two! It’s got the spirit of what attracted me to Tone It Up and keeps me here — vitality, fun, friendship, the ocean, the beach. I love the surfing footage. Thank you for creating a community where one woman’s victory is another woman’s happy dance and motivation, and one woman’s struggle is received with care and love and returned with encouragement to not give up. Thanks for the love, Katrina and Karena and TIUHQ!

  42. Video is awesome and so motivating! Can’t wait to start tomorrow — my 15 year old happened to catch the video and is now doing the program with me! Thanks again – she’s excited, too!

    1. Aw that is so sweet! Tell her we say hi! That’s the age I really got into working out and eating healthy too :) So empowering as a teen!

  43. AWESOME video!!! What an inspiration you two are and so proud to be part of this community you made! I think I’ll have the bikini series video on repeat while I meal prep today:) Thank you for the changes of the plan too~I love them!! Definitely will help me stay more consistent. Now to get my new workouts downloaded:) XOXOXO!!!

  44. Omg this made me so nostalgic! I remember the FIRST bikini series! You girls have been such an inspiration to me and have completely changed my life :) Can’t wait for this year’s bikini series!

  45. This honestly made me tear up! I joined TIU the night before the first Bikini Series and this bought back all the feels!! What a journey we have all been on. I was watching this and just had Kelley Jame’s ‘Summertime on my Mind’ playing in my head. Cheers Bikini Series Babes! Here’s to the best 8 weeks of the year <3 <3

  46. Happy 5th Bikiniversary to everyone at TIU, but especially to our precious and fearless leaders, K & K!!! Love y’all!

  47. So happy about the throwback! It’s why I became a TIU girl in the first place. (Fun fact – my husband proposed to me 25 years ago on Manhattan Beach to the right of the Pier).

    P.S. I’m a 45 year old with back issues – I can’t do all the moves, but I adore the joy you Ladies (and your crew) put into every video, the food from your meal plan is pretty and tasty, and the protein powder is the only one I drink now! While it’s been fun going along to the exotic locales of the last few Series – Manhattan Beach is the best. Please take us on video tours of the streets and little shops one day please – film a walking workout along the strand and up and down the hill to the Beach. Such goodness in your backyard – no wonder you two are so Happy!
    Thanks K & K for having such a fun business.
    Oh and those classic workouts that can still be found on the internet are golden! Good then, good now. <3
