What kind of product is it?
Elevate your performance and redefine your edge with the Strong Fit Zip Up Tank — where function meets fashion in every stitch. This top is made for women who move with purpose and wear their strength like a second skin.
The clean, structured stand-up collar adds dimension, while the sturdy front zipper delivers both bold style and functional ease. Quick to slip on, quick to power up — this detail-forward design gives you control and cool all in one.
Engineered with contrast stitching from armhole to waist, these flowing lines visually contour the body, highlighting the waist and enhancing natural curves. The result? A flattering silhouette that boosts confidence with every rep.
Designed for freedom, the sleeveless cut ensures full range of motion — perfect for weightlifting, running, or any upper-body intensive training. The design subtly balances broader shoulders and adds a dynamic visual edge, making it as empowering as it is performance-driven.
The classic racerback style not only enhances ventilation but also shows off your upper back definition, letting your hard work shine through.
Crafted from our exclusive MUSPRO™ performance fabric — a premium double-sided 220G nylon blend (69% Nylon, 31% Spandex) — this tank offers strong, supportive stretch with moisture-wicking capabilities that keep you cool and dry. Durable, responsive, and soft to the touch, it's made to move with you.
A subtle yet sleek heat-pressed logo on the chest adds to the minimalist power aesthetic, enhancing brand recognition without disrupting the clean lines of the design.

Just received my order and the packaging looks great. Everything feels high quality right out of the bag. Super excited to wear these pieces — Firm abs never disappoints!

These camo leggings look amazing and feel even better. The military vibe is so cool, and the pockets are super practical. Squat-proof, comfy, and always get me compliments — my go-to pair for gym or daily wear.

These denim cargo leggings are super comfy and stretchy. The pockets really stand out and make them different from other leggings. True to size, very flattering on the waist and butt. A friend recommended them and I’ll be back to try more styles.

I wasn’t sure about the hollow design at first, but it looks amazing on and still feels super supportive. The fabric is soft and breathable, and I can lift or run without having to fix it all the time. Honestly one of the most stylish bras I own, and still totally functional.
I’ve shopped at Firm abs more times than I can count. Every order proves why I keep coming back—unmatched quality, fit, and style.

Wore these through squats and cardio—no sliding, no see-through. Super comfy, soft, and the scrunch detail really gives a nice lift. Definitely my go-to leggings now.

I’ve been a Firm abs customer for years and every package reminds me why I keep coming back—great quality, perfect fit, and styles I love.

These leggings hug in all the right places, super flattering and comfortable for both workouts and daily wear. The color is stunning and I get compliments every time I wear them!

Love this brand so much, the quality of the material is really thick and the shape of the clothes fits my physique really well.

I have the black set and love it, but this gray color is just as stylish. Comfortable, supportive, and easy to wear for workouts or daily outfits.

Wore these from riding in the morning to errands later—super comfy, not see-through, and the pockets keep my phone safe. They hold their shape even after a full day, which makes them my new go-to leggings.

Really like this bra, super comfy and the cut-out makes it look different. Good support for workouts, and my jacket from here matches so well too.

These pants are way better than I expected! The waistband is super comfortable and adjustable, so they fit just right without digging in. I love the drawstring cuffs — I can wear them loose or cinched for a sportier look. The fabric is lightweight and breathable, perfect for warm days, yet still feels durable. Plus, the pockets are actually functional (finally!). Stylish, comfy, and practical.

I’ve tried so many leggings, but these are on another level. They stay in place during squats and cardio, and the high waist gives me extra support. I wear them for my workouts, and they don’t slide or roll. The sports bra is super supportive too – perfect for both gym and yoga.

I absolutely love Firm abs! This green jumpsuit is super comfy and looks amazing, and my new package just showed up too. The quality and styles never disappoint — I keep coming back for more.
I’m such a fan of these zip up workout tops that I keep ordering more. They fit so nicely and the cut of the tops are so flattering. I have bought about 8 of these amazing tops. I’m so obsessed with these tops that I check their website for new colors and styles that I don’t own yet 🤭 I just ordered the cargo highwaisted workout pants in black with the red on the pocket but they were out of my size so I clicked for them to let me know when my size is available 🤞 I 💯 recommend this company’s clothes because what I have received and wore , I love the fit and quality of their products. ⭐️ ⭐️⭐️⭐️⭐️
Both the white and black tops of this item are outstanding. Well made, great fit, and sexy if you wear it that way. My wife LOVES them!
