Peter Kraus is still in the running for Rachel Lindsay's heart on The Bachelorette's thirteenth season.

On The Bachelorette's premiere last month, Peter, a 31-year-old personal trainer and business owner from Madison, WI, stepped out of a limo first and also received the first rose at the Night 1 Rose Ceremony. 

Rachel and Peter's romance quickly heated up when they enjoyed a one-on-one date to Bark Fest together with the Bachelorette's dog Copper. Peter bonded quickly to Rachel and her dog, and it was clear Rachel had butterflies for the suitor.

A group date followed in which Peter was asked to take his shirt off and dance for women in The Ellen DeGeneres Show audience.

Peter didn't exactly feel comfortable stripping his clothes off for a rowdy crowd, but he admitted he'd do just about anything for Rachel. Curious to learn more about him?
