15 Celebrity Workout Clothes Photos Featuring Gym Gear You Can Actually Buy IRL

Next time you’re due for a workout, take note: Activewear is no longer comprised of a simple tank top and shorts. Recently the treadmill is its own runway, and we’re looking to celebrity workout clothes photos on Instagram for our fit and style inspiration. Of course, if a band tee from high school and soccer shorts are your jam, that's totally cool — but some studies have shown that wearing "fancy" workout gear can actually make you more motivated.

Activewear has increased its cool factor, as brands such as Lululemon, Under Armour, Nike, and more are providing us with neon colors, fun patterns, and pieces to mix and match that make working out feel as expressive and luxurious as the outfits our everyday wear. In fact, a lot of it is literally becoming everyday wear, as the athleisure trend continues to go strong in 2015.

Who better than to advertise this oh-so-fabulous workout gear than super hip celebrities, am I right? Below are 15 celebrities whose enviably gym wardrobes are actually totally attainable.

1. Rumer Willis

Willis is constantly in workout gear, thanks to practice for Dancing With the Stars. After all, I'm sure it takes a lot of core work to master those lifts with dance instructor and regulation hottie Val Chmerkovskiy. This look was styled by Amazon Fashion Activewear, which offers gym separates at just about every price point.

2. Kris Jenner

Momanager was on top of her fit game Monday morning thanks to a little encouragement from son Rob, showcasing her newest pair of kicks from Athletic Propulsion Labs.

3. Rosie Huntington-Whiteley

This Victoria's Secret model puts in the work for her heavenly shape. Above the angel works out at a Body By Simone studio in New York City, flaunting footwear courtesy of Nike.

4. Lena Dunham

Making sure to balance work and her workouts, Lena Dunham paused for a selfie documenting her efforts. Always promoting positive body image, Dunham looks nothing but fierce in her sports bra and patterned leggings styled by Bandier Fit.

5. Janel Parrish

Having been a finalist on Dancing With The Stars last season and playing the role of Pretty Little Liar's villain-turned-heroine Mona Vanderwall, it's no surprise that Janel Parrish stays active. Here Janel looks fab in a set of stylish sweats, compliments of Material Girl by Madonna and Lola.

6. Karlie Kloss

Hitting the streets of the Big Apple upon her return, Karlie Kloss went for a run in black and white Nike sneakers and leggings.

7. Julianne Hough

Julianne Hough takes a locker room selfie, flexing her bicep and showing her appreciation for DWTS runner-up Amy Purdy's Element Eden activewear line.

8. Lea Michele

Dancing lessons weren't all Lea Michele got out of working with Kate Hudson on the set of Glee! The co-star supports fit wear brand Fabletics as she sips a green smoothie post-workout, simultaneously providing Hudson with some free exposure.

9. Whitney Carson

Whether she's beasting it winning Mirror Balls on Dancing With The Stars or working up a sweat in rehearsal, I find it extremely challenging to find a reason not to crush on Whitney Carson. Practicing with The Bachelor's Chris Soules, Carson looks adorable in a Onzie hot pink sports bra and FunKeys Clothing pants.

10. Demi Lovato

Demi Lovato has made strides to recover from her unfortunate past of eating disorders and body dysmorphia and continues to encourage those suffering to embrace self-love and body positivity through posts all over her social media accounts. Catching her in action, Lovato lunges on to her couch sporting a pair of Skechers.

11. Kate Hudson

Once you get past the fact that Kate Hudson isn't actually working out in the picture above and instead shooting a commercial to advertise her activewear line Fabletics, you probably don't care because you're too busy obsessing over all the perfection in her black and white track jacket and her friend's purple and pink patterned leggings.

12. Kylie Jenner

Hate it or love it, I think we can all agree that Kylie Jenner has some interesting taste when it comes to her style. And while her top is not what I would consider gym-appropriate, the Reebok ZPump sneakers on her feet are definitely a runner's dream. Mine included.

13. Alessandra Ambrosio

Brazillian model and VS Angel Alessandra Ambrosio prepares for a red carpet event by engaging in a quick yoga session outdoors, naturally looking flawless Victoria's Secret active gear. Standard.

14. Gisele Bündchen

Though she may have (or may not have) retired from the runway, we highly doubt we'll see the day when supermodel Gisele Bündchen retires from fitness. Who wouldn't want an excuse to wear these Under Armour goods every day?

15. Ashley Graham

Last, but far from least, Sports Illustrated model Ashley Graham is all kinds of inspiration. You can look as fabulous as Ashley Graham compliments of Nike, and feel as good as the model, following along with her partnered line of webisodes with Net-A-Porter entitled "Curvy Fit Club."
