FAQs

Always follow our sizing guide and measure your waist at its narrowest point. If you’re between sizes, we recommend sizing up for comfort. A well-fitted trainer should feel snug but not restrict your breathing.

If you’re just starting out, begin with 1–2 hours a day to let your body adjust. Over time, you can gradually increase wear to 6–8 hours daily for best results. It’s important not to wear your waist trainer for 24 hours straight or while sleeping, as your body needs time to rest. Consistency is key — regular use combined with healthy lifestyle choices helps you see results.

Yes, you can! Many people choose to wear their waist trainer during workouts to enhance sweating, improve posture, and support core engagement. However, it’s best suited for low- to moderate-intensity workouts like walking, strength training, or light cardio. For high-intensity exercises that require deep breathing, like HIIT or running, you may prefer removing it for maximum comfort and safety. Always listen to your body — if you feel short of breath or restricted, take it off.

We don’t recommend sleeping in your waist trainer, as your body needs time to rest and breathe freely overnight.

That’s up to you! Most people wear their trainer under fitted clothes for a seamless look, while others prefer over a light top for added comfort. We can recommend wearing it over a fitted top to prevent rubbing against the skin.

Hand wash in cold water with mild soap and air dry. Avoid machine washing or drying, as this can damage the fabric and structure.

Many new moms find waist training helps with posture and support during postpartum recovery. Always consult your healthcare provider before starting waist training after childbirth.

Strength training, walking, cycling, and light cardio pair well with waist training. Always listen to your body and adjust as needed.
