I love this trainer! This is my second one buying I went from a medium to small within three weeks! At first i did not believe it would help me throughout my fitness journey and it did! I workout in the morning and after i get ready for my day I wear The Waist Trainer for about 4-5 hours a day, i noticed when i eat with the trainer on it helps me control the amount of food i consume, it also helps with my posture! I will be buying my 3rd waist trainer very soon!
