Two things determine the size and shape of your butt: the size of your butt muscles and how much fat you have in the butt area. While numerous exercises, products, and machines claim that they have the secret to a bigger booty, some are effective and others simply are a scam.
If you want a bigger butt, you have to increase the size of your butt muscles- the gluteus maximus, gluteus medius, and gluteus minimus. As lunges have become a popular butt exercise, some suggest that lunges may flatten and tighten your butt, while squats make them rounder and firmer. To get the best results, you should do both. Squats will shape, tone, and increase the size of your butt, while lunges will keep everything tight.
