I'm considering waist training I want to get down to an 18" waist but I'm scare if it's realistic how long it can stay that size and if it's unhealthy? I'm really skeptical. But like currently I like having a 22" waist. I just want to get smaller because I'm a smaller person I feel like I look better with a smaller waistline. I want to at least get down to 20. Would this help? And when would I get results?
