Science says there's a reason to splurge on a cool pair of printed leggings or a stylish tank top: It can actually help motivate you to work out. For real!

It's called "enclothed cognition," which is a fancy way of explaining the mental shift you experience when you wear certain clothing. One study suggests clothing can influence your behavior and attitude because it carries symbolic meaning (think: an actress putting on a costume to get into character). If what you wear can subconsciously change the way you act, simply slipping on gym clothes can give you that extra push to bust out a quick work out.

So gear up for the New Year with these 13 items—they'll give you that mental boost you need to break a sweat in 2017.

Under Armour Gym Bag
You'll need a way to tote all your new gear around. Whether you're headed to work or to work out, the bag's special compartments—such as a side stash pocket for valuables and a padded laptop sleeve—will keep you organized. 
Available at underarmour.com, $54.99.
Sweaty Betty Yoga Leggings
Two for the price of one? You had us at "two." But it's also worth mentioning the high waist and high-quality fabric of these tights hug you in all the right places.
Available at sweatybetty.com, $52. 
C9 Champion Plus Size Tank

Regular trips to the gym mean you need enough tank tops in your arsenal to get by between laundry days. Stock up with an affordable yet still high-performance option, like this sweat-wicking top.
Available at target.com, $18.99.

C9 Champion by Anna Kaiser sleeveless hoodie
This twist on a classic hoodie is a fun way to wear the style. Wear it alone to show off your hard-earned arms or throw it on over a long-sleeve for a cool, layered look. 
Available at target.com, $24.99.
Nike Running Shorts
You can't go wrong with black running shorts (they match everything), but this pair is anything but basic, thanks to the flash of reflectivity on each leg.
Available at nike.com, $45. 
Old Navy Pullover
The funnel-neck hood and bright neon color caught our eye, but it's the high-tech fabric, which keeps you warm and dry during outdoor runs, that made this a new fave. 
Available at oldnavy.com, $18-$32.
Brooks Running Sports Bra
Let's be real: You're not going anywhere until the girls are secured. This bra, especially beloved by big-busted women, holds up through high-impact workouts. The customizable clasp and adjustable straps let you dial in the fit so you can move comfortably. 
Available at brooksrunning.com, $65.
Eddie Bauer Light Jacket

The whisper-thin jacket is a multitasking top layer: Wear it alone on a windy day or layer it over a fleece for warmth and protection from the elements. It rolls up to the size of a fist, so it's the perfect piece to toss in your bag when traveling.
Available at eddiebauer.com, $50. 

Reebok Strappy Bra
Gone are the days when bra straps were meant to be hidden. We'd stick to low-impact workouts when wearing this bra, but its weblike design will make you feel like a total badass.
Available at reebok.com, $50. 
Montiel Backless Shirt
Further proof that bras aren't meant to be hidden: open-back tops. Not only does this design completely eliminate the part of the shirt that gets the sweatiest (ick), but it was also strategically intended to be worn outside the gym. Swap your sneakers for moto boots, and you're good to go for the day. 
Available at montiel.com, $48. 
NB x J. Crew long sleeve

This special collaboration combines the performance of New Balance gear with the style of J.Crew. Small details such as reflective trim and ruching on the sleeves mean this is not your average raglan.
Available at newbalance.com, $44.99. 

American Giant Joggers
What do you toss over shorts or capris on your way to the gym? A warm pair of track sweats like these. They come in eight colors, so there's an option for every taste, and a modern fit means they never look frumpy. 
Available at americangiant.com, $59.
Athleta Headband
Hair should never be a distraction from crushing your workout. Slide on a headband like this. The elastic grippers will ensure the headband and your hair stay in place. 
Available at athleta.com, $12.
