A new all-in-one digital platform will begin offering certified, trainer-led live group fitness classes in tandem with personalised nutrition programming and wellness tracking.

Called Openfit, the new platform is the brainchild of Jon Congdon, one of the co-founders of at-home fitness and nutrition group Beachbody.

Among the services offered is Openfit Live, a group fitness element with more than 350 weekly live trainer-supervised workouts broadcast via digital streaming.

Classes will be capped at 40 attendees and trainer's will be able to offer real-time feedback, motivation and coaching to the subscriber through optional use of the user's phone camera.

Openfit will also feature hundreds of on-demand workouts featuring celebrity trainers – including Andrea Rogers, Devin Wiggins and Tough Mudder X Champion Hunter McIntyre.

Openfit will at first be made available on Openfit.com, alongside devices using iOS, Android and Roku operating systems.

Congdon – who will lead Openfit as CEO – said the ability for trainers to provide personalised motivation and guidance to those taking part at home in a similar way to a small group boutique studio is a "technology first" for the fitness sector.

"We developed Openfit to be an all-in-one platform for healthy living,” Congdon said.

“Members can now access live and on-demand workouts and personalised nutrition plans and tracking all within one app, removing common barriers to success and making health goals achievable for everyone.”

Selina Tobaccowala, Openfit chief digital officer, added: "Our goal is to democratize this experience, and make it possible for everyone to benefit from the accountability, community and results that come from having a live trainer providing immediate feedback in a tech-enabled small group setting."
