Thanks for your question -
You've hit on three different categories of improving your contour -
Exercise
Exercise is an important part of looking and feeling great. However, there is no such thing as targeted weight loss. This means that as you lose (or gain) weight you don't lose or gain it from a specific area - but instead lose it from everywhere. The ratio of how you lose it can be different and can change as you age.
Liposuction (any technique)
Liposuction surgery removes fat from specific areas. So if your concept is to improve your contour by reducing certain areas this can be very effective. Liposuction has some limitations if you have excess skin or are significantly overweight.
Brazilian Butt Lift
This surgical technique takes the benefits of liposuction (in reducing areas of prominent contour) and adds the ability to increase areas that need additional profile.
I hope this helps.
