Waist trainer?

Has anyone ever tried using a waist trainer while working out? Does it help at all? Does it help with your results any faster? I’m debating on getting myself one but didn’t want to spend the money if it doesn’t actually help or show any results any faster than working out like normal. I still workout regularly but if a workout waist trainer will help me get results faster or better then I’m all for it! However, I’m on the fence about getting myself one. No shame, I’m just curious an am seeking some advice on the product! Thank you all in advance!! 💕
