Biohazard vocalist and bassist Evan Seinfeld addressed the fitness habits of metal fans in a recent appearance on Trunk Nation With Eddie Trunk. He discussed the launch of his new fitness app, Full Metal Fitness.
Seinfeld explained why he decided to create the app, noting that many longtime fans of the genre share similar lifestyle habits as they’ve aged alongside the music.
“All my fans, the guys like you and me who grew up listening to [Judas] Priest and [Iron] Maiden and [Black] Sabbath and Metallica, are all our age,” Seinfeld said. “They’re in their 40s, 50s, 60s. And I gotta be honest and call it how I see it. It seems like 90% of the fans of metal are out of shape, overweight, eating toxic food, not exercising, not working out.”
Seinfeld was careful to clarify his intentions behind the comments, framing them as motivation rather than criticism.
“And [I’m] not like saying it in a judgmental way,” he continued. “I’m here to inspire, and I’m here to help. I really got into helping people. This is like my new thing that gets me excited.”
Full Metal Fitness is more than a passing mention on a podcast — it’s a fully built platform that Seinfeld has been developing to give his message real structure and staying power.
The app blends at-home workouts, meal planning, and accountability tools designed specifically with longtime metal and hardcore fans in mind. Members get a customized workout program along with an easy-to-follow meal plan built around fitness and longevity, rather than quick fixes or fad dieting.
Seinfeld has built a personal touch into the platform as well. Members training virtually can join a weekly Full Metal accountability video call led by Seinfeld himself. Those who sign up for the platinum and diamond membership tiers get one-on-one video coaching directly with him.
Full Metal Fitness also offers a free at-home workout option for fans who want to try it without committing to a paid tier. The option requires nothing more than a set of five- or 10-pound dumbbells and a yoga mat or soft floor space, giving Seinfeld an accessible entry point designed to lower the barrier for fans who haven’t exercised in years.
The app is as much about community as it is about fitness. Seinfeld has said he wants Full Metal Fitness to bring together “badass metalheads and hardcore fans” working toward getting in shape together. The platform turns a shared love of heavy music into shared motivation for a healthier lifestyle.
