“It’s kind of like a music festival, except we’re doing it a little more healthy,” says Booth. “Everybody can work their butts off, come with their friends, have a good time and enjoy some drinks afterwards.”

“Everybody’s got their own style of working out,” he adds. “I’ll be doing myBoothcampworkout that I do across the country from my Boothcamp app. So we’ll be doing full body, HIIT-style — just getting after it for about an hour.”

And while he spends most of his time focusing on his fitness these days, Booth says he still manages to squeeze in a few hours watchingTheBachelorandThe Bachelorette. So what’s his advice forBecca Kufrinwhen she goes public with her fiancé after next week’s finale?

“Because you don’t even see any of that when you’re on the show, right?” he continues. “You just assume you’re the only guy, even though you know there are other people there. It’s always extremely tough, so they’ve just got to trust and support one another.”

The Bachelorettefinale airs Monday at 8 p.m. ET on ABC.
