Waist Shape & Train

The Slimtum® PRO waist trainer has been developed from first principles for waist shaping during exercise. Every layer and component complement this philosophy and the result is better waist training, better support, better range of motion, better comfort and better durability. Previous designs for gym waist trainers were just medical back braces that happened to shape the waist. The Slimtum® PRO is the first waist trainer designed as both a waist trainer and a supportive belt for the gym… that’s why the ALL the top pros wear it.

Fitness Ready Chic

Our expert designer is no slouch when it comes to style! Blackened chrome metal accent, mélange detailing, soft rich sheeny blacks, subtle logos and lineal details elevate any gym set. We chose a monochrome palette to go with any colorway you wear so you’re never out of step.

Gym Tested Durability

Tested and tortured by IFBB pro athletes, the Slimtum® PRO is a serious piece of gym equipment. The demands of exercise routines for gym waist trainers far exceed those of regular waist trainers. That’s why we designed and tested this belt together with pros, to give you a waist trainer that will truly last the distance. Our high durability and abrasion resistant materials ensure lasting quality.

Support in the Gym

The PRO features our cleverly designed, high density H pad back support with an inner comfort liner. This special pad has just the right density and shape to provide optimal support in the gym, while maintaining comfort and range of motion for exercise. The elastic bands lock the pad in place during wearing to provide maximum security without interfering with the PRO’s waist training performance.

Freedom for Fitness

What good is support without freedom? Our design team balanced the concerns of gym goers around support and freedom of movement. You can squat, plank, burpee, crunch, run or do just about any exercise you can think of in freedom while wearing our PRO. What’s more, we specially designed this waist trainer to stay in place on you while you exercise, so you don’t need to constantly adjust!

Superior Waist Shaping

Our design team are experts in waist training. Bringing their knowledge from years of working with latex waist trainers and elastic shaping bands, they were able to design a waist trainer for the gym that puts waist shaping first. Every layer works together to improve the shaping performance of the PRO. There are no useless materials in this trainer – only pure shaping performance in every layer.

Waist Train in Comfort

Developed with comfort in mind, the PRO waist trainer has flexible and elastic elements throughout the design. Every layer stretches and molds to your body providing the best comfort possible. From the outer binding, to the support pads, to the base layer (which is just stiff material in other “gym waist trainers”), to the top bands: everything is made to move with you in comfort.

We use single measurement sizing for our waist trainers – measured around your small of waist. 

To find your size, wrap a measuring tape around your small of waist (as shown in the image). Look up your small of waist measurement in the SMALL OF WAIST column in the chart. Find the range your measurement fits in. Your PRO waist trainer size is in the SIZE column to the left of the appropriate range. 

NOTE – WE HAVE SIZED OUR WAIST TRAINERS ACCURATELY to work for your current small of waist measurement. Please order the size of waist trainer shown as smaller sizes will not fit.

NOTE – OUR PRO WAIST TRAINER DOES NOT MATCH THE SIZING OF OUR OTHER WAIST TRAINERS. Please size your PRO separately.

Want to put your waist trainer in the washing machine? No problem with the PRO! Simply put your PRO waist trainer in a washing bag and throw it in. We designed this trainer to be wash and wear ready, with low water absorbent materials and sturdy machine washable construction. Hand washing your waist trainer is a thing of the past with the Slimtum® PRO.
