Losing an incredible 117lbs (53kg) has been utterly life-changing for Zrinka.

Now she is strong, confident and happy again after years of uncontrollable weight gain which left her feeling depressed and ‘worthless’.

Zrinka had struggled alone with her weight for years, gaining more than 99lbs (45kg) over five years.

The 34-year-old sales director was 275lbs (125kg) at her heaviest point, was eating over 4,000 calories a day, and was desperately unhappy with her body and the way she felt.

Nothing she tried ever worked. Ketogenic, vegetarian and juicing diets had all failed, and she just felt lost and helpless of ever achieving a long-term solution to her weight loss struggle.

Constantly tired, lethargic and low on energy, she feared she had thyroid problems or diabetes.

What doctors found were dangerously high cholesterol levels.

With a family history of heart problems and diabetes, Zrinka made a commitment to change her life and her health for good.

Sixteen months later and Zrinka is unrecognisable from her old self after completing a body transformation at Ultimate Performance.

More than 110lbs (50kg) lighter, healthier and looking stunning with a whole new wardrobe, Zrinka is thrilled with the lasting lifestyle changes she has made with the help of U.P.


  • We show you the best, we don't show you the worst.
  • We show you people who follow the plans, not those who are all talk.
  • We show you those who inspire even us with their commitment to their results.
  • You cannot get results exactly like these. You are unique and that means you can only get your own best possible results.

  • Oftentimes the lower your starting point (poor fitness, terrible body composition) the better your results.
  • We cannot do the work for you and the results you see here are a testament to the work ethic of our clients.
  • Our reputation is that we are the best trainers in the world for helping you to unlock your potential, & we can lead you to the door, give you the key, even turn the handle and push the door open, but we cannot walk through it for you.
