Nick, 36-year-old software salesman from Waukesha, WI, was selected as the star of The Bachelor's 21st season after three failed attempts on the franchise -- two on The Bachelorette and one on Season 3 of Bachelor in Paradise.
However, with every passing season and broken heart, Nick became more and more buff.
He began his The Bachelorette journey back in Season 10 as a bit of a nerdy and modestly built guy, but over time, he has transformed himself into quite the muscular, stylish and confident hunk.
To achieve the body he has now, Nick must have spent countless hours in the gym and followed a strict healthy diet, so now it's time to see the results and appreciate the hard work Nick has put in.
