Should I get butt implants? How should I improve the look of my body? (Photo)

There is no single best weightlifting exercise for the glutes, but there are a number of highly effective ones. Being a dedicated weight lifter, you have very slender thighs and are very familiar with the best exercises to tone your buttocks: squats, dead lifts, hip thrust, glute-ham raise, and lying side hip aduction. Implantech produces a contourflex gluteal round implant which is gentler on tissues and easier to use than most other profiles.
Measurements need to be taken, and your anatomy should be assessed with an exam by a board certified PS. In the interim, consult with a board certified PS via email or Skype.

Thank you for your question. You are an excellent candidate for buttock augmentation with implants. I prefer the 2 incision approach which allows a much quicker and easier recovery with intra-muscular implants. Best wishes to you.

Typically a combination of sculpting the waistline with liposuction and augmenting the buttock with implants +/- the hips with implants provides the best chance for a long lasting and desirable "hour-glass" figure. However, please keep in mind that a physical exam is always first necessary before providing any final surgical recommendations. Based upon your photos, a Stanton Anatomic shape buttock implant may serve you best. Rib removal is rather drastic and considered a “long run for a short slide” outcome. Please also keep in mind that an extremely few number of board certified plastic surgeons perform buttock implants on a regular basis so please make sure to seek consultation with a reputable buttock implant specialist. Glad to be of help.

you seem to be an excellent candidate for a buttock implant procedure. Be sure to choose a board certified plastic surgeon who specializes in this procedure and is well known for it.
