Never used Corset waist trainer made specific to Adam Bonilla's requirements after years and years of using squeems and other waist trainers that simply didn't get tight enough. This corset waist trainer is adjustable in size by many inches, unlike other waist trainers that get loose over time defeating the purpose of wearing them. It's small enough to sit specifically in the area that needs cinching above the iliac crest (hip bone) and below the ribs for ultimate tightness on the waist without any bones holding the cinching back. The system used by Team Elite Physique for waist training is specific waist training techniques the last 4-6 weeks before a show and wearing the corset as such: 5 weeks out 2 hours per day plus a leather belt tight during workouts 4 weeks out 3 hours per day plus a leather belt tight during workouts 3 weeks out 4 hours per day plus a leather belt tight during workouts 2 weeks out 5 hours per day plus a leather belt tight during workouts 1 week out 6 hours per day plus a leather belt tight during workouts
