Gym Underthings

Ooooh la la….

Lulu thong

One of the frequently-asked questions when I post workout pics or a video:

How do you avoid panty lines?

So the secret, friends, is the picture above! Feel free to sing that Sisqo song, even though I was, like, 5 when that came out. 

The answer is thong underwear. If you’re not a fan, you might not be wearing the right type or size, but for workouts, I tend to stay away from the pure cotton or lacy variety and have two drawers: one fancy/nice and the other for workout/comfy. I used to keep them mixed together but after the great silly-bow-sticking-outta-my-pants incident of 2008 (it was a gift, it was also 2007), I realized that some things in life are not multipurpose.

Here are some faves for workouts:

The lululemon Light as Air thong (above). At $16, they’re kind of pricey for what they are (as is everything at lulu) but the quality is great and like the name suggests, feels like you’re wearing nothing at all

 VS No Show Sport Panty ($12.50 or 3 for $33). For the comfort and fabric, these are a great deal. Bonus: they come in cute colors, too.

Favorite sports bras:

Flow y

lululemon Flow Y bra ($42). This is my favorite “everything” bra. Perfect for weights, yoga, light/moderate cardio, teaching, lounging, sleeping, everything. It’s seamless with stretchy, comfy fabric. It also manages to escape the uniboob look that many sports bras create so beautifully.

Sports bra

Champion Smoothie Bra ($38). This is now my go-to sprinting and race bra. The straps are so comfy and can easily be switched to a racerback, the cups are soft and SUPER supportive- keeps the girls in place. 

So spill, friends: what do you wear under your workout gear? Any faves? Thongs or nay?

I’m excited to read your answers!

    I have never considered wearing (or even buying) thong work out undies. I have a few pairs of regular thongs for when I need to wear them – but I just don’t like wearing them that much…ever.

    I have a couple of pairs of workout undies that are not cotton. I can’t wear cotton underwear when working out – it just rubs me the wrong way (ha!). I don’t really care if I have panty lines – I haven’t even checked in the mirror to see if I do have them..opps?

    • Carolyn on December 20, 2012 at 1:38 am

      Rebecca I am soooo right there with you! I really don’t like thongs…at all. I just feel…uncomfortable? I’m not sure.. just don’t like them. So I stick to m victoria secrets lace and cotton undies.

      And sometimes I wonder, as I am running on the treadmill facing the window with lines of people behind me staring in that same general direction, whether I have really obvious panty lines. But then my speed interval kicks in and I am so focused I completely forget the thought.

      And if I’m not thinking about it, no on else is! Right? Ha, it is like the lie we told ourselves as kids “If I close my eyes, no one can see me.” 🙂

  2. Ashley M. [at] (never home)maker on December 19, 2012 at 7:38 pm

    A thong while working out sounds like madness to me! Hahaha. I don’t wear anything. I thought that’s why shorts come with the built-ins? And if I’m out running in the cold in my tights, I don’t really care about panty lines. As for bras — this has become an issue since I started breastfeeding. I used to be able to wear whatever, but now I need more support. I have some Lulu tanks and bras and they are great despite the $$$.

  3. Stephanie on December 19, 2012 at 8:05 pm

    Maybe I’m old school but the thought of leaving the house without ANY underwear on seems kind of gross to me. Not judging, just had NO idea so many of you worked out without underwear. Moving on, I wear a thong because I also would feel like I had a diaper on trying to workout with full underwear on. To each his own I guess. And lastly, whoever could spin Gina’s post about comfy underwear to workout in into a debate have waaaayy too much time on their hands….

    I think everyone should do the 26 random acts of kindness… This world needs it!

    • Fitnessista on December 19, 2012 at 10:47 pm

      agree <3

  5. Fitsouffle on December 19, 2012 at 9:20 pm

    Have you ever tried the brand commando for thongs? They are a little pricey too, but they are seamless and so comfy!

    • Fitnessista on December 19, 2012 at 10:47 pm

      no, i’ve never heard of them! will check it out 🙂

  6. Karen @ Runner Girl Eats on December 19, 2012 at 9:28 pm

    I workout commando…TMI? If I do decide to wear something underneath my shorts/tights, it is definitely a thong. Too much bunching with briefs. As for sports bras, I have yet to find a bra that doesnt need to be doubled up to fully support the girls.

    • Kristy @ Kristy's Health Revolution on December 20, 2012 at 9:44 am

      Exactly. I really don’t understand why people think going commando under workout clothes is gross…that’s kind of the point, right? That’s why they put hygienic liners in most workout clothes! Plus, I think it’s WAY more gross to be constantly picking at underwear that are bunching, sagging and riding up!!

      • Christine on December 20, 2012 at 7:51 pm


    • Heather on December 20, 2012 at 2:42 pm

      Lulu’s Ta Ta Tamer is the only sports bra I found that can support my ladies fully. Totally worth the money 🙂

  7. Heather on December 19, 2012 at 9:31 pm

    I love the 26 acts of kindness idea! Thanks for passing it on. I will be participating now, too! <3

  8. Nikki on December 19, 2012 at 10:46 pm

    Commando is the only way to go! 🙂 Love this topic Gina

  9. Jenn on December 19, 2012 at 10:52 pm

    I have tried many types of undies for working out and I too have a separate drawer for workout stuff including my workout undies. I have a few different Lululemon style thongs and I find some of them sit too low for my liking and don’t feel comfortable. I have some cheap cotton ones that I usually wear. I’ve also tried some Lulu full-backs that aren’t supposed to show the lines, but they aren’t comfortable.

    For bras, I had to buy the Ta-Ta Tamer from Lulu when I had my son in August. I’m breastfeeding and needed the extra support. I can run in that sucker with milk-filled boobs and it holds the ladies in tight with no flopping. You can switch the straps to racer-back, which is how I wear it all the time since all my tanks are racer-back.

  10. Michele on December 19, 2012 at 10:57 pm

    I wear thongs every day and also for working out. They are so comfortable to me. Once you have worn them for a while, it’s hard to wear regular underwear. To not wear anything under pants just seems icky to me. Also, depending on the workout, I may wear the pants more than once and IMO you could not do that if you didn’t wear something underneath them. I don’t spend a lot on my undies though. I usually get Maidenform on sale at Kohl’s and just wear whatever I grab.

  11. Roselyn on December 19, 2012 at 11:01 pm

    The only thing that offends me about this post is that you made me feel old when you said you were 5 when the Thong Song came out. I was in college…and old enough to drink! Gah!

    But really, I haven’t figured out my undies situation yet. Nothing seems comfy to me! I’ll try the thong thing. 🙂

    • Fitnessista on December 19, 2012 at 11:13 pm

      i was in high school! i just said i was 5 because i thought everyone would be able to tell i was joking haha

      • Emily on December 20, 2012 at 9:46 am

        When I read “5” I was slightly distressed…I’m 28 so I was in high school (and on Spring Break the first time I heard that song). Anyway, I was thinking, “please tell me she’s joking, and how old is sheeeee!? 5?!” Hahaha…glad to know my irrational fit of feeling old was just that…irrational 😉

      • Amy M on December 20, 2012 at 4:02 pm

        I totally had to look up the year that song came out! I was like no way!!! LOL.. I was 19 when it came out.. and I know yo are younger.. but I did not think you were that much younger! 😉

  12. Kate on December 19, 2012 at 11:14 pm

    Thongs all the way, my friends. Wear them to the gym, to yoga, even when I’m riding my horse. I’ve been wearing them for years though – my riding coach had me in thongs to prevent visible underwear lines through my breeches. Hanky Panky makes my favourites – they’re costly, but worth it.

    • Lisa on December 20, 2012 at 10:04 am

      Hi fellow horseback rider! I always wear boyshorts to prevent underwear lines in my breeches. Also, I wear breeches that are like two sizes too big so they are pretty baggy (I hate riding in tight clothes…weird I know).

  13. @pluvk on December 19, 2012 at 11:40 pm

    Thank you for sharing the 26 random acts of kindness link. All those ways that people are showing their love and appreciation for one another is amazing! 🙂

  14. Alyssa on December 20, 2012 at 1:19 am

    Thanks Gina, what bras did you find offered the most support while breastfeeding?
    BTW, I dont seee anything wrong with wanting to look good in work out clothes. Everyone wants to be the girl in the gym that looks hot! 🙂

    • Sarah on December 20, 2012 at 4:26 pm

      Being “the girl in the gym that looks hot” is the least of my concerns…

    • Fitnessista on December 21, 2012 at 12:50 am

      i wore a tank with a shelf bra in it, and a sports bra OVER that. sounds totally weird, but it worked for me!

  15. Laura on December 20, 2012 at 2:01 am

    Kind of off topic from this post but would you consider doing a review of the Pop Pilates DVD? Would love to know your thoughts about it before purchasing 🙂 Love your blog!

  16. Elise on December 20, 2012 at 8:35 am

    The only beef I have with this post is that Gina has a better butt than me 🙂 Write on, Gina! Great post!

  17. Becca on December 20, 2012 at 9:16 am

    I’m super late to the game here, but I used to wear thongs to the gym for years. (I had a drawer of “workout thongs” from target and a drawer of “real thongs” from VS or wherever.) But then I spent a year abroad at the end of college in a VERY VERY dry environment and (total TMI here) dry environments + excessive sweating = chafing in areas that are very sad to have chafing. So, I just stopped wearing underwear. All and all it feels about the same, just less adjusting 😉

    Also, this is a totally okay topic. People who have issues with this clearly have other insecurities. Its nice to be able to talk to other women/fitnessistas about stuff like this. Who else are you going to talk to about it??

  18. Reghan on December 20, 2012 at 9:31 am

    Always thongs for working out or just every day wear. I hate panty lines! I wear full bottomed underwear to bed at night and that is the only time. I think thongs are the comfiest things ever lol

  19. Missy @ Life After Morning Coffee on December 20, 2012 at 2:38 pm

    When I want to prevent panty lines, I wear boy shorts. But for working out, I usually go commando (if I’m wearing running shorts with built ins) or just wear whatever underwear I’m wearing that day. It also depends on what I’m doing. If I’m running or doing cardio, I want something that won’t chaff (spelling?) but if I’m just lifting weights, underwear doesn’t matter too much to me.

    I have yet to find a sports bra that isn’t supportive enough. I don’t feel like I have ginormous boobs where I should have a problem. But I do. Whenever I do jumping jacks or running, I feel like a bimbo! Ugh! 🙁

  20. Katy Widrick on December 20, 2012 at 3:12 pm

    I was a C(+) before pregnancy and as a nursing mama I am a D — maybe a DD. OUCH!

    So, I double up on the sports bra (the Moving Comfort Fiona is $$$ but can be used as a nursing bra!) and yes, I too am a thong-tha-thong-thong-thong girl.

  21. Kim on December 20, 2012 at 7:30 pm

    Thongs always give me UTIs, and I’d rather sport a panty line than a camel toe… so briefs it is! 🙂 I always thought my sister & mom were so odd for sleeping in thongs and then complaining about chronic UTIs, seems like a clear connection to me.

  22. Natalie on December 22, 2012 at 7:06 pm

    Just wanted to say thanks for sharing the 26 acts idea. As a new mom, too, the Newtown tragedy hit me hard, and one layer of the mourning was helplessness. Already, my first 7 acts have helped me feel like I am in control, and not the fear or grief that resulted from that devastating loss. There is still good left, and we can all be a part of it!

  23. Awkward Camel Toe on December 28, 2012 at 2:58 pm

    I’ll never understand why ladies worry about panty lines and camel toes.
