Just a lil throwback! I used to me addicted to this song! We should totally have a HIIT workout to it yeah? And I should dress up! Fun fun! Who else should be in the throwback line up?

<3 Cassey

  • Amber

    I love this song, but in the mix I’d like some faster based beats like NSYNc dirty pop may be a good one? Oh and this wasn’t true popular probably but I love the song Space Jam haha

  • Amanda

    Obsessed with this! I sent it to Tone It Up!

  • Danielle

    MMBop by Hanson. But it could be MMPop Cardio ;)

  • Belinda

    You should do NSYNC “I want you back” and have it target the lower back/muffin-top area! Orrrrr NSYNC “BYE BYE BYE” and do a bye bye bye to cellulite in your inner and outer thighs video! Love you and your workouts! Best shape (inside and out) in my life!:)

  • Maggie Crowson

    I’m a newby to your site and I am in LOVE. Love me some throwback songs-would definitely look forward to those :)

  • Lani

    YESSSS. Britney! And BSB and Nsync too! Love the idea of a throwback! And would love more dance cardio, just did Gangnam style a bunch of times!

  • steph

    Spice girls!

  • Brooke

    I’m sorry but if you do a workout to this song you’ll just never be able to top it. It would literally be the most perfect thing I ever laid my eyes on.

  • Jessica

    OMG! I was and always will be a Britney fan! This song takes me back to high school. A HIIT workout would be awesome to this song!

  • Maria

    Hi, Cassey!

    Please do a challange or something and use the song “Wonder ” by Naughty Boy ft. Emeli Sandé!
    Today when I was sad I gave this song a listen and it really cheers you up in an instant!

    Hugs from Sweden <3

  • Catt

    Crazy In Love!
    Me & You (maybe for stretching!)

  • Ashley G

    I have never commented on your blog before, but yes! You have to do some throwback videos for sure:)

  • lena

    i’m in ! oh gosh, i was addicted too ! but i’ll be in martinique in the caribean islands so i don’t know how u can get me in the line lol

  • Kelly

    I second all the suggestions above! It would be totally fun!

  • I was thinking some Christina! We could get a little Dirty or I think you could do something awesome to Candyman

  • C.

    Hiit me baby one more time is such a must! the title asks for a hiit workout!
    other ideas:
    ‘n sync: “i want you back” (how about a i-want-that-pre-baby-bod-back workout?)
    or: backstreet boys: “everybody” (rock your body workout)
    or of course: spice girls: “wannabe” (i wanna really really really wanna have a nice butt) ;)

    • Lisa

      THIS. I second all of these. Plus, Christina’s “Genie in a Bottle” or “Come on Over.” 5ive’s “When the Lights Go Out.” Spice Girls’ “Spice Up Your Life.” Britney’s “Oops I Did it Again.” Seriously…late 90s pop is my soul music.

  • Naomi

    And No doubt is a must!!

  • Shana

    I think The Spice Girls should be included in the throwback!

  • Thank you for bringing this song back into my life! Put ya hands up if you were ever B-Spears for halloween!

  • Anaa

    hey cassey check this out! you’ll probably wanna try it.

  • Elle

    lovin’ the No Scrubs suggestion – that would be hilarious!

    And I’m totally feeling Cher’s Believe. DIVA!

  • ash

    OMG yes please to this!!! (!!)

  • Emily

    YUP! Do it! I agree with some Destiny’s child! Throw in some No Doubt! Can’t wait.

  • Val

    Christina Aguliera: Genie in a bottle
    TLC: No Scrubs
    Destiny’s Child: Independent Women

  • Sarah-Jane

    Backstreet Boys for sure ^.^/
    Oh and maybe also Five :p My guilty pleasures as I am more of an Avenged Sevenfold/Bullet for My Valentine Girl now a days lol

    • Rose

      Yeeeeeees! Five would totally motivate me as I was a huge fan of them as a teenager :D But HIIT me baby one more time owuld also be great!

  • Carla

    a Destiny’s Child medley

  • ME! ME! ME! Do it! Pleeease!

  • Sam


  • Rae

    Yesss oh my goodness Britney Spears was a goddess when I was in grade school, awesome throwback song! Those pink puffy ponytail holders will always remind me of that music video.
