The Thermal Workout Vest is uniquely designed to insulate the heat and stimulate fat & water loss in the waist area. It works as a mobile sauna suit for your waist, burn your belly fat and make weight loss more effective. It can also help improve blood circulation & get rid of toxins by promoting sweating while exercising.

The Thermal Workout Vest provides:

  • instant abdominal compression
  • lumbar support while clinching and slimming your waist
  • increases and traps body heat to the abdomen area which results in more sweating for burning belly fat.

You’ll instantly lose up to 3 sizes off your waist as soon as you secure the trainer. For lasting results, wear it for 6-8 hours daily for 4 weeks, and you’ll lose up to 4-inches off your waist. Simply slip on the trainer every day, and watch the sexiest version of you emerge.

We here at Lu Bella Fashion understand the frustrations of correct sizing. So here’s our guide to the best fit. To get the best fit possible place measuring tape one finger (👉🏾) above the belly button and around the waist area. If you fall in between sizes you may order the size down! Sizing may vary depending on cut and style. Please use the guide below to determine the most accurate size for your fit.
