Waist trainers have really taken off over the past several years, with celebrities like Kim Kardashian, Christina Milian and Beyonce wearing one to help them achieve that classic hourglass figure.

However, waist trainers can be used for more than just shapewear. If you are looking to shred a few pounds at the gym, waist trainers can potentially help to reduce lower belly fat as the tight belt or vest makes you sweat more.

This buyer's guide explains what a waist trainer is, how it works, and whether it is safe to use.

What is a waist trainer?

A waist trainer is a modern version of the corset, a device which became popular during Victorian times. This undergarment is made from thick fabric and hard metal boning. It is worn around the midsection and cinched up with a lacing system, hooks, or Velcro. It is intended to be worn much more tightly than shapewear to give you a smaller waist.

Do waist trainers actually work?

Despite some people wearing a waist trainer to get a smaller waist, it is unlikely to work for that.

Dr Galyna Selezneva, a medical doctor at the Dr Rita Rakus clinic in London, told the Huffington Post: "Formal corset training takes a year of dedication and is not a quick fix to achieve a small waist. People such as Dita Von Teese have spent years training their body and waist through proper use of corsets."

If you wear one underneath your clothes, it may enhance the curve of your waist. However, it will show, in this case, you are better off wearing shapewear instead of a waist trainer.

Are waist trainers safe?

Like most health and fitness trends, there are some factors to be cautious about when looking into the best waist trainers for women. Wearing one will take some getting used to and may not be for everyone. One thing to be particularly aware of is your overall lung capacity and if wearing a waist trainer impacts your breathing. If you can't breathe properly, take it off.

Mary Jane Minkin from the Yale school of medicine says: "Once you take the garment off, your body will return to its usual shape. It's also uncomfortable, restricts your movements, and if you wear it really tight, it can even make it difficult to breathe and theoretically could cause rib damage."

"Medically, it doesn't make sense that cinching your waist tightly will make it permanently smaller," says Mary Jane Minkin, M.D. clinical professor of ob-gyn at Yale School of Medicine.

Naturally, it's not really a comfort garment, so be careful and stop using it if your body tells you to stop. It would be best if you also were cautious wearing it while working out at home or at the gym. Whenever you're doing physical activity, you rely on breathing correctly so you don't get injured, again don't wear your trainer if it's impacting your ability to breathe.

Generally, as long as you are not addicted to your shapewear and are not wearing it all the time, you should feel free to enjoy it. However, remove it if it starts to hurt you or restrict your breathing.

Sizes available: 3XS-6XL 
Colours available: 2 (black and beige) 
Review: "I found my size on the chart, which would have been a size large, and decided to size down one size to a medium. I secured the waist trainer on the largest hooks right away. Had I not been able to, the trainer graciously included a size extender. The bones are rigid and hold their form but do not restrict your movement. I feel very held when wearing this. I own a much more expensive waist trainer that the Kardashians were peddling a few years ago. I feel very confident wearing this under most outfits when I go out. I'm so happy with my purchase. I will gladly repurchase in a smaller size when needed."

I bought this product after rave reviews, and let me just say this is one of the best decisions I've made. My chiropractor recommended that I straighten my posture, and already after one day of use, I feel an instant improvement.
