Tummy tuck vs. liposuction for more defined waist?

I’m 42 years old, 5’3” tall and weigh 130 pounds. I run and work out 4-5 times a week and eat healthfully. I had one child naturally 19 years ago. The scar in the picture is from a partial colectomy 2 years ago, but it does not bother me. I just want to feel comfortable and look good in my clothes. I would love to have a waist line and not a spare tire around my middle, but I’m not sure what is reasonable to expect and whether I need a tummy tuck or lipo.
