I’ve been a big girl my entire life, and I’ve also always been a babe who loves to move her body. Especially boutique fitness workout classes, HIIT workouts, dance classes, hip-hop hiking, you name it I’ve done it. In 2025, I took 288 workout classes, walked millions and millions of steps (I have the oura ring data to prove it) and prioritized moving my body in ways that made me feel good. I took 100+ bar three classes over 50 Pilates classes and even filmed 20+ YouTube workouts for plus size women, and explored new workout formats I’d never tried (hello, F45).
So needless to say, I am very opinionated on the best activewear for plus size women. I want to take a workout class and wear a cute set that makes me feel confident comfortable and allows me to move and flex through any workout. So these are the best five brands for plus size activewear.
Best Plus Size Activewear Brands (Tested After 288 Workouts in 2025)
Let’s get into it.
1 | Vitality
jumpsuit (2x) | grippy socks | water bottle
I’m just going to say it, you could honestly stop right here and ignore all of my other plus size activewear recommendations because Vitality is the absolute best for plus size activewear. Think really cool color ways, interesting patterns, and the most comfortable activewear you will ever try.
jumper (3x) | sneakers (tts) | water bottle | water bottle bag
And what I love most is that they are a 100% inclusive site, meaning that every single piece they create comes in sizes XS-4X! A huge win, and such a rarity when it comes to clothing companies in general.
2 | Spanx
I’m sure when you think of Spanx, you likely don’t think of activewear… You think of great shape wear, and their iconic lounge collection, right?! And while yes those things are amazing, so too is Spanx activewear and IMO it’s one of the most underrated brands for plus size in general. Especially if you are like me and you’re both plus size and petite. Spanx creates petite lengths for plus size babes, and this includes their activewear too! Truly ingenious if you ask me.

The quality is exactly as you would expect from Spanx, it’s impeccable. And I personally love the fit and the fabric. These pieces are top notch on all fronts and I’ve worn them to literally everything.

I’ve worn my Spanx sets hiking up sand dunes in Peru, to countless barre3 classes, and all of my hot girl walks with my pups. Spanx activewear seemlessly transitions from a workout to everyday for me, and I just love their pieces so much.
3 | P.E. Nation

I learned about P.E. Nation a few years ago when I was perusing the very limited plus size section at Revolve, and fell in love with the brand. I especially like P.E. Nation activewear for HIIT style workouts, running (which I rarely do), barre3, and pilates classes. What I love most, is that the majority of their leggings have a drawstring which means I don’t have to worry about them rolling down. Their pieces are a much more classic activewear feel rather than the more buttery soft “brushed cotton” feel that is very popular right now.

My only qualm with P.E. Nation is that their sizing is very limited and things tend to sell out very quickly. So if you like something and it’s available in your size, you’ll likely need to purchase it right away. I can’t tell you how many times I’ve waited to purchase a piece from them, to find it gone the next day.
4 | Athleta
similar tank | leggings (2x)
I’ve been a major fan of Athleta ever since they launched plus size back in 2019. Fun fact: they were one of the first activewear brands I worked with when I started influencing (photo above, is from my favorite project I’ve ever done with them). They have the most variety when it comes to plus size activewear: hiking pants, a variety of leggings for any workout occasion, and they even have some incredible loungewear and work wear pieces too. While we are on the topic of work wear pieces… thank me later if you grab these for yourself, they are the most spectacular pair of wide leg trousers I’ve ever tried. More details on this in this post.
I personally am a huge of Athleta’s Salutation collection. It’s what I wear most to my workout classes, and also really love their Ranier collection which is a more technical collection for outdoor running, hiking and walking. They kept me super warm on my winter hikes when I was living in Colorado.
5. Beyond Yoga

Beyond Yoga is known for their buttery soft leggings, and they are seriously, deliciously soft. These leggings have the lightest amount of compression, so if you are looking for something that won’t squeeze you, the Beyond Yoga is your girl.

When it comes to sizing, I wear my true to size leggings, however their tops tend to run a little smaller for me so I do recommend you consider sizing up. Especially if you’re a bit bigger in the chest area.
Honorable Mentions
OLD NAVY: TBH Old Navy activewear is more of an honorable mention for me, and I am including it because it’s the most affordable brand to buy plus size activewear. It’s hit or miss for me but if you are new to fitness or don’t want to drop over $100 on a workout set, then Old Navy is the place for you.
PELOTON: This brand is super new to me, I’m talking I just got my hands on a set less than a month ago. Spoiler, it’s really really good. But I haven’t worn it enough, or tested out any other sets from their collection to put it in my top recommendations.
ADANOLA: I own a few pieces from Adanola, and while I do like them, I have to caution you because their sizing runs small and their pieces are quite snug on me. It’s not a fully inclusive brand, but if you are on the smaller side of plus (size 20 or lower) then this brand could be one for you to consider.
Okay, if you’re a plus size babe like me I’d love to know where you are shopping for activewear. I’m always looking for new brands to try that make me feel confident and comfortable no matter what workout I’m doing.
