1. Gymshark Flex Legging Review


  • Sizing: True To Size
  • Fabric: 56% Nylon, 39% Polyester, 5% Elastane
  • Coverage: 95% squatproof

Description: Gymshark Flex Legging

The Gymshark Flex legging is one of the OG Gymshark leggings and still popular till today! You can easily tell the Flex leggings apart from other Gymshark bottoms by the heavy branding on the backside of the waistband.

Fabric & Fit

The Flex legging fabric is super stretchy with a rough textured feel . These leggings have a subtle contouring on the backside that actually makes your booty pop!

Although the Flex legging is thick and compressive, they’re still flexible enough to move with you through your workouts.


The waistband is thick, ribbed, and extra compressive for support. Trust me when I say that this waistband is not rolling or slipping anywhere! 

Are The Flex Leggings Squatproof?

It’s easy to pass these leggings off as 100% squatproof until you get under some real lighting. I stick a white tag and bright pink tag underneath my leggings and bend over in front of a bright fluorescent ring light (that’s really the only thing I use my studio ring light for ha!).

I found that all of the Gymshark leggings I tried were not really 100% squatproof. I give them a 5% negative squatproof rating because with nice brightly colored panties and perfect fluorescent lighting (like at a gym), and the right booty angle, your underwear will be spotted.

You’ll need nude or dark-colored underwear for your Flex leggings, but luckily, the thick and textured legging fabric will hide any panty lines.

Gymshark Flex Sizing Review

For reference, I’m a 27″ waist, 32″ bust (DD cup), 38″ hip, 5’8″ tall, 31″ inseam, and US clothing size 4-6.

Flex Legging Sizing Tip: “The Flex legging fits true to size, so I recommend going with your waist size on the size chart. These leggings are super compressive so I don’t recommend sizing down.”

2. Gymshark Vital Seamless Legging Review

The Vital Seamless legging is another Gymshark staple and definitely one to consider if you’re looking to invest in your first pair.  


  • Sizing: True to size
  • Fabric: 55% Nylon, 33% Polyester, 12% Elastane
  • Coverage: 90% squatproof
  • Features: DRY technology

Fabric & Fit

The Vital seamless legging is the dream: soft, stretchy, and flexible with a high compression fit.The Vital Seamless fabric compression is comparable to the Flex legging, although the fabric is not as thick. It’s also softer and stretchier than Flex and Ultra Seamless.

I’m raising a camel-toe alert for these leggings. I thought the seam-free front design would prevent that but I guess not.


The waistband is about 4″ wide, ribbed, extra compressive, and sits right above my navel. These leggings will hold you in without squeezing the life out of you. Plus the waistband stays in place through everything- squatting, walking, sitting on the couch- you won’t have to tug on your leggings! 

Are the Vital Seamless Leggings Squatproof?

The Vital seamless leggings are almost 100% squatproof. As long as you stick to dark or nude-colored underwear you’ll be safe. Also, since the fabric is on the thicker side, you won’t have to worry about panty lines and folds.

Vital Seamless Legging Sizing Tip:
“The Vital Seamless leggings fit true to size, so I recommend going with the size chart. However, the fabric is stretchy enough to get away with sizing down.”

3. Gymshark Ultra Seamless Legging Review

The Ultra Seamless legging is the Spanx of Gymshark leggings: it has a super high rise fit; compressive waistband; a sculpting/shaping yet comfortable fit, and gives you a figure that’s to die for!


  • Sizing: True to Size
  • Fabric: 54% Nylon, 38% Polyester, 8% Elastane
  • Coverage: 95% squatproof
  • Features: Shaping

Fabric & Fit

The fabric is thick, textured, and stretchy with a high compression fit. The Ultra Seamless legging texture and compression feel very similar to the Flex legging,which makes sense since they have almost the same fabric composition.

Also, I was very surprised to find that the waistband does not roll, which is very unusual for super high rise leggings.

Is The Gymshark Ultra Seamless Legging Squatproof?

Like most of the other Gymshark leggings, the Ultra seamless legging is not 100% squatproof, but it’s pretty close. You’ll need dark-colored underwear but the thick fabric will hide panty lines and folds.


 Gymshark Ultra Seamless Sizing Review

Ultra Seamless Legging Sizing Tip:”This legging fits true to size so I recommend going with the size chart. It’s stretchy enough (more than Flex) to size down if you want a more compressive fit, but I think it fits perfectly as is.”

4. Gymshark Speed Legging Review

The Gymshark Speed Legging is a newer addition to Gymshark’s many items and a great go-to pair for working out and everyday wear!


  • Sizing: Runs small
  • Fabric: 80% Nylon, 20% Elastane
  • Coverage: 95%
  • Features: Pockets

Fabric & Fit

The Speed legging fabric is stretchy, mildly compressive, and probably the softest Gymshark legging I’ve ever tried. FYI, these leggings run small and the waistband is really snug, so you may find yourself struggling to get them on!

After I finally got into the Speed legging and saw my brand new butt – thanks to the heart-shaped waistband and booty contouring seams- I pulled off the tag. Then I proceeded to take a nap in them and woke up with my leggings almost completely greyed out from lint.

This fabric will attract a lot of lint, so if you have a pet beware. I still love the leggings though even if I have to take a lint-roller with me wherever I go!


The Speed leggings have a widish 3.5″ waistband which may sit at your belly button depending on your torso length. The waistband is secure and fits snug around my waist- no gaps, no rolling, no slipping.

The pockets are surprisingly deep and can fit an iPhone plus without pulling the leggings down.

Is The Gymshark Speed Legging Squatproof?

Like the other leggings, the Speed leggings are almost %100 squatproof, but you’ll need dark-colored or nude seamless underwear. Also, you should know that the Speed legging fabric is thinner and clings to your body, so it shows panty lines and folds.

Speed Legging Sizing Tip:
“The Gymshark Speed leggings run small so if you prefer a relaxed fit, I recommend sizing up. On the other hand, if you prefer a tight/comrpessive fit, stick to your true size. I definitely don’t recommend sizing down!”

5. Gymshark Sculpt Legging Review

The Gymshark Sculpt Legging is another great workout and everyday legging and is really similar to the Speed legging.


  • Sizing: Runs small
  • Fabric: 80% Nylon, 20% Elastane
  • Coverage: 95%
  • Features: Pockets

Fabric & Fit

The Sculpt legging fabric is super soft and stretchy with a medium compression fit.

Also, the Sculpt leggings are baby scrunch leggings- they have a subtle ruching in the backside designed to accentuate your booty. Although, the ruching in these leggings don’t really give that booty-shaping effect that the Speed legging has.


Much like the Speed legging, the Sculpt legging waistband fits really tight.The top seam digs into my waist and the front dips lower than I’d like.

The waistband is firm, but the narrow waistband means you only get low midsection support. Plus the waistband slides down a bit so the coverage is even less.

If you need leggings that can hold your life together while you workout, then the Sculpt leggings might be a match for you. There are two side pockets that can fit a larger iPhone. 

Is The Gymshark Sculpt Legging Squatproof?

The Sculpt leggings are almost 100% squatproof, but you’ll need dark-colored or nude seamless underwear. Like the Speed legging, these leggings have a thinner fabric that clings to your body and shows panty lines and folds.

6. Gymahark Lustre Legging Review

The Gymshark Lustre legging is another stylish new addition to the Gymshark stock, although it’s not my favorite fit.


  • Sizing: Runs small
  • Fabric: 87% Polyester, 13% Elastane
  • Coverage: 95%

Fabric & Fit

The Lustre legging fabric is soft and stretchy with a medium compression fit. The narrow V-front style waistband falls at my navel and fits so snug that you may struggle to get into them.

These leggings are not particularly flattering in my opinion, but I love the embossed tiger stripe pattern and the slight sheen to the fabric.

I did notice that the embossed part is more flexible than the plain parts of the legging, so you’ll notice more stretch from the waist to mid-thigh than the lower leg area.

Is The Gymshark Lustre Legging Squatproof?

Like the other Gymshark leggings, the Lustre leggings are almost 100% squatproof. You’ll need dark-colored or nude underwear but the fabric will hide panty lines and folds.

If you’re looking for more midsection coverage, the Lustre legging may not be the best option.Like the Sculpt legging, the Lustre legging has a smaller waistband (2.5″) and will barely get to your navel depending on your torso length.

How To Care For Your Gymshark Leggings

Most Gymshark leggings fabrics are pretty sturdy so they don’t need much TLC. But if you follow these basic guidelines, your leggings should last you a few years!

Avoid excess heat from washing in hot water, tumble-drying, or ironing as this can affect the strength of the fibers and degrade the fabric features.

Instead, wash your leggings in cold water, and use a drying rack. If you plan to use a dryer, set to the lowest heat for 10-20 minutes depending on how much you have in the dryer. Also, avoid using fabric softener since it can seal the fabric, causing the fabric to become less breathable.

Place your leggings in a mesh bag before throwing them in the washer. This will ensure that the fabric doesn’t get snagged by parts from other clothing.

Air out your workout clothes after each workout session to prevent bacteria from ruining your activewear fabric. You don’t need to wash your leggings after each wear, but don’t dump your damp leggings in the laundry basket.

Follow these steps to keep your Gymshark activewear in pristine condition!
