Best Waist Trimmer Reviews

Isavera Fat-Freezing Waist Trimmer

Our Rating


Why we love it: Backed by science, doesn’t require exercise when using, 90-day money-back guarantee. 

The Isavera Fat-Freezing System waist trimmer is one of the most popular waist trimmers we’ve picked due to its very unique way of helping you lose weight. There are two powerful ways in how it helps shed fat; first is through fat freezing wherein the wrap causes fat cell apoptosis (cell destruction) and second is through cold thermogenesis, this is where the cold temperatures burn calories and shrink fat cells. 

It’s designed for waist trimming but can also be worn on the thighs and arms to help reduce cellulite in those areas. There’s quite a bit of science behind their approach to “freezing fat” with this system and it does work if you’re patient. 

Included in the pack are three of the ice packs, a massager, and calipers to measure circumference and body fat percentage. It’s important to note that you don’t wear this one while working out though. Instead, you wear it while you’re doing stuff around the house like cleaning or watching Netflix. It also comes with a 90-day guarantee so if you try it out for 3 months and don’t like it, you can send it back. Overall, it’s a great waist trimmer and definitely worth using.

What makes this waist trimmer special?

  • Backed by science
  • Doesn’t require you to work out
  • 90-day money back guarantee
  • Very comfortable to wear 


  • Science-backed waist-trimming system
  • Dual-action Gel packs 
  • Cold-insulating Neoprene Shell
  • Anti-slip inner lining 
  • Product dimension: 7 inches wide and 52 inches length

SHAPERX Waist Trainer Belt

Our Rating


Why we love it: It gives you an instant hourglass figure, stays on, and has built-in support for your lower back. 

The SHAPERX Waist Trainer Belt gives you an instant hourglass figure the moment you put it on. What we liked about the SHAPERX is that it’s breathable but that’s also somewhat of a downside because generally, you want to sweat when you’re wearing them. The breathable fabric also absorbs sweat so it takes a little more effort to clean which isn’t necessarily a big deal but something to consider. 

What we also liked about this waist trimmer is that it has 4 acrylic “bones” built-in which aid in core stabilization and lower back support. The bones are somewhat flexible so you can still bend and move while you exercise without interference so this wouldn’t substitute for a weight belt. This extra support also makes it a good belt to wear during the day to keep your posture on-point while you work.  

When wearing it during a workout, you’ll notice it’s pretty low profile under a loose shirt. It also doesn’t bind up or slip around. When you put it on, it stays snugly in place and doesn’t stretch out or loosen up after sweating. What we did find is that the sized run a little large though. So, if you’re a medium according to their size chart, you probably want to order a small. 

Lastly, this waist trimmer also helps new and recent moms to get their figure back. If you just had a baby, you can also use this to support your tummy and help you with postpartum recovery. 

What makes this waist trimmer special?

  • Built in acrylic “bones” for additional back support
  • Breathable fabric
  • Multiple colors available 


  • Double strong velcro adjustments
  • Stretchable and breathable
  • Available sizes (Small, Medium, Large, X-Large, XX-Large)

Venuzor Waist Trainer Belt and Waist Trimmer

Our Rating


Why we love it: Excellent support, not just a waist trimmer, but a trainer belt too. 

The Venuzor waist trainer and trimmer is made out of comfortable, adjustable, and stretchable fabric that provides excellent support. It features a double hook and loop closure that really stays in place no matter what you do. The first is on the inside of the belt and the second is a larger, wrap-around that’s less likely to get sweaty and ensures that even the most demanding workouts won’t cause it to come off. 

It’s made from latex-free neoprene fabric that stays in place both under and over your clothes and it doesn’t pinch or irritate your skin which is always nice.

Many women choose to wear this one as part of their postpartum recovery and report that it’s hands down the best solution. They say the support is the best you can get. That being said, we didn’t have any postpartum ladies to test it with so we can’t say for sure. At the time of this writing, it’s very affordably priced and comes in sizes ranging from small to XXL so you can find one that’s just right for your waist.

That being said, if you have a longer torso, this is only 7” in width so it may not cover your entire stomach area. The best thing to do is to measure the height of the area you’re hoping to cover. If 7” won’t cut it, then opt for one of the other options on the list. 

What makes this waist trimmer special?

  • Excellent support with a double hook and loop closure
  • Lots of colors available
  • Affordably priced at the time of this writing


  • Available sizes: Small, Medium, Large, X-Large, XX-Large
  • Lots of colors available 
  • Provides a tummy tuck and back support 
  • It is super functional and can be used as a corset as well. 

Sweet Sweat Premium Waist Trimmer

Our Rating


Why we love it: It’s made from premium materials and is very effective for weight loss!

Get ready to get back in shape as the Sweet Sweat premium waist trimmer is specifically designed to help you sweat more during workouts. It comes in a variety of sizes ranging from small to XXL so no matter what your size, you can find one that fits your waist. Furthermore, it’s flexible so it adjusts to your shape and size while you move and it’s contoured to make it that much more comfortable. 

On the effectiveness side of things, it comes with a special gel that you put on your stomach to activate sweat production. The gel seems like a gimmick at first but it really does work and you WILL sweat. Speaking of sweating, the latex-free neoprene belt has a grid lining that’s non-slip and repels moisture so it doesn’t slip or bunch up during your workout. It’s also easy to clean and doesn’t smell after wearing it. To clean it, you just run it under some water and wipe it down. Super simple.

Another necessary feature for us is the visibility of the belt. You don’t want something that’s noticeable and screams “I’m wearing a waist trimmer belt”. When wearing the Sweet Sweat under your clothes, it keeps a low profile. If you wear a moderately loose fitting shirt, nobody can tell that you’re wearing it. 

Overall, it’s an excellent belt that’s affordable and comes with a few perks like the sweat gel and a carrying bag. 

What makes this waist trimmer special?

  • Double Velcro Closure
  • Includes a sweat enhancing gel
  • Comes with a free carrying bag


  • Product sizes: 
    • Small (8 inches width x 35 inches length)
    • Medium (8 inches width x 41 inches length)
    • Large (9 inches width x 46 inches length)
    • X- Large (10 inches width x 51 inches length)
    • XX-Large (10 inches width x 60 inches length)
  • Free Bag and Sweet Sweat gel
  • Double velcro for Extra support
  • Durable Overlock Stitching
  • Non-slip surface and grid lining that absorbs moisture

ActiveGear Waist Trimmer Belt

Our Rating


Why we love it:  Perfect for bigger men and women, affordable, several velcro straps for added security.  

The ActiveGear waist trimmer belt is a lightweight, wrap-around training belt with a neoprene lining that stays in place under or over your clothes. Like several of the other belts, it’s built to fit you even as you lose weight. This is thanks to the velcro strap that secures anywhere on the belt. And unlike the Mcdavid or Perfotek, the ActiveGear has two velcro straps to keep it in place. The one that sticks out from the end of the belt and another sewn into the belt itself. This provides a good level of grip and holds up well during your workout. 

Another perk is that it comes in two sizes. The medium is 8″ wide and 42″ long, and will fit up to a 48″ waist, while the large size has an extra-wide design at 9″ wide and 46″ long, and it will fit up to a 52″ waist. 

In our experience, it was easy to clean with a little soap and water. It didn’t get any mildew smell or anything like that. Just make sure you hang dry it and don’t leave it wet and bunched up. 

What makes this waist trimmer special?

  • 42″ & 46″ lengths for smaller and larger users
  • Multiple velcro straps for a tighter wrap


  • 2 sizes available: medium and large
  • Anti-slip technology
  • Designed to repel moisture and bad smells
  • Additional Velcro Strip

Mcdavid Waist Trimmer Belt

Our Rating


Why we love it: At the time of this writing, it’s one of the most affordable options. 

The Mcdavid Waist Trimmer belt is made up of high-quality breathable fabric with a non-slip neoprene lining. The lining does a good job of keeping the trimmer in place while you’re working out and works equally well whether you wear it under or over your clothes. However, the lining does feel a little cheap and there were many reports of the lining tearing during workouts. We didn’t experience this issue but you can tell it’s not built to last a lifetime. 

Additionally, it has a “one size fits most” size. The idea being that it’ll fit you now and as you lose weight because it wraps around you and has a large velcro strap to secure it anywhere.

However, in our experience, one velcro strap can wear out after a few months so we would like to see a little more security. That being said, at the time of this writing it’s one of the most affordable options. It’s simple to use, it’s unnoticeable when worn under clothes, and adjusts to your size as you lose weight. 

What makes this waist trimmer special?

  • Breathable fabric
  • At the time of this writing it’s the cheapest option


  • One size fits most – up to 40” 
  • Breathable and lightweight 
  • Adjustable strap 
  • Aids posture improvement

Perfotek Waist Trimmer Belt

Our Rating


Why we love it: Very similar to the Mcdavid and also very affordable. 

The Perfotek waist trimmer is very similar to the Mcdavid above and has very similar features. It’s a one size fits most design with a single velcro strap that can be secured anywhere. It’s made with a neoprene, latex-free inner lining that stays in place on your skin or over your clothes so it doesn’t move around when training. That being said, much like the Mcdavid, the Perfotek has some flaws. You can tell it isn’t built for longevity and indeed there are several reports of it tearing after a short time. 

That being said, it’s not all bad. When you wear it during a workout, you can hardly feel that it’s there. You’ll also sweat like crazy so take it off in the bathroom if you don’t want sweat getting everywhere. The fabric is also breathable and it’s easy to clean with just some warm water and soap. Overall, it’s a toss-up between the Perfotek and the Mcdavid because they’re very similar in pretty much every way. The main difference is that the Perfotek can fit up to 42” while the Mcdavid only goes up to 40”. So if you’re slightly larger, opt for this one. 

What makes this waist trimmer special?

  • 42″ length for larger waists
  • Breathable fabric and an anti-slip neoprene coating


  • Easy to Clean
  • Can fit up to 42 inches
  • 100% Neoprene Material
  • Fully Adjustable Velcro Closure

What is a waist trimmer and who should buy one?

A waist trimmer is a kind of belt that is fastened around your waistline. This helps to reduce the excess fat in the midsection and allows your body to sweat the excess water which contributes to weight loss and a leaner appearance. Waist trimmers also help with posture, new moms that just had a c-section, or anyone who wants to burn fat fast should get a waist trimmer. It’s very effective and it fits the budget as well.

How to choose the best waist trimmer

Comfort & material

Most waist trimmers are made from latex-free neoprene material that’s sweat-resistant and prevents the belt from slipping and moving while you’re wearing it. The materials all relatively consistent with the primary differences being whether or not they have support bones and how they’re fastened. You want one that has at least a few velcro straps and a hook and loop closure. 


Waist trimmers are stretchable but it doesn’t mean that it fits every body shape. You want to make sure that size that you’ll get has an allowance enough to cover your waist and to be comfortable while wearing it. Be mindful of the length and the width because you might have a long torso so you’ll have to pick a waist trimmer that has a wide belt for your midsection to be fully covered. Lastly, check the thickness of the waist trimmer. You don’t want to look bulky while wearing it and you might not feel comfortable if it’s too thick.


Most waist trimmers are cheap so you don’t need to worry about spending much. The exception being the unique trimmers like the Isavera that uses fat freezing technology. If you’re not ready for the Isavera level waist trimmer, opt for something that’s mid-range. Not the cheapest because these tend to break down and cost you more in the long run. 

Read reviews

Checking other customer reviews is always useful. That’s where you’ll know if the waist trimmer is worth the price. You’ll also know how durable it is, how flexible, and how comfortable it is from the people who have already used it. And of course, you’ll see how effective the waist trimmer is and you might even find some inspiring photos. 

Know how the product works

Not all waist trimmers work the same so you have to know how to use it. There are instructions provided in the package to help you set it up and will show you all the details including the maximum time that you should wear it. And because some of them include gel and other accessories, you’ll need to make sure that you follow the instructions.

Waist Trimmer FAQ’s

What size should I get?

To make sure that you’re getting the right size for your waist, you can measure it using a measuring tape. For example, if the size of your waist is 30″ the advisable size for your waist trimmer would likely be a medium. You want it to fit snugly with the straps fully in place. 

Can you wear the waist trimmer under your clothes?

Some people opt to wear their waist trimmer over their clothes which is perfectly fine. However, you can also wear it under your clothes if you prefer. Just make sure that you’re wearing a relatively loose-fitting shirt because a tight shirt will show through. We recommend that you clean your waist trimmer before wearing it against your skin as well. There can be residue left over from manufacturing that may irritate your skin otherwise. 

Will it come off or slide down during exercise?

Waist trimmers are made from non-slip material and are designed for exercise. So they should stay in place even on your most intense workouts. Just make sure that you lock it up just right to prevent it from moving.

Do you have to exercise for it to work?

It depends on the product. The Isavera, for example, is designed to be worn around the house and not when you exercise. However, most of the other belts are designed to increase sweat while you workout, and as you already know, you should follow a good diet and exercise regimen for the best results. 

How long should I wear a waist trimmer for each day?

It is not recommended to wear it all day as it may cause discomfort or irritation after a while. You also don’t want to sweat all day so it’s better if you take a break. Each waist trimmer has a recommended time that you wear it for each day which is written in the manual. Generally, it’s about an hour per time but some people wear them several times per day so check the manual and use your judgment.
