|Hi, I'm 23 years old, and 5'7 tall, and I'm getting married in 3 months. To fit into my wedding dress I need to lose 4 inches in my waist, 2 inches in my hips, and 2 inches in my bust. I also have some back fat that I want to get rid of. I'm not sure what exercises to do to help with this; I heard that sit ups don't do anything?? Please help, I need to get started!!! Also, I would prefer to do this at home is possible. HELP!!
